COVID-19 Updates

ANAHEIM – A wide range of factors can cause myocarditis; most often viral infections cause myocarditis in children and teens, according to Ryan Butts, MD, medical director of the pediatric advanced cardiac care program at the University of Texas Southwestern Medical Center and Children’s Health of Texas.

Dr. Butts provided an overview of what pediatricians and other clinicians caring for children and teens should know about myocarditis at the annual meeting of the American Academy of Pediatrics.

The important new things that attendees may want to take away from this for their practice are improved recognition and diagnostic workup for acute viral myocarditis, making sure cardiology follow-up occurs after an admission for the condition, enhanced evaluation of the child before they return to competitive sports, and the availability of written or verbal education for patients relating to COVID vaccine–associated myocarditis, Dr. Butts said.

He also provided a set of key takeaways:

• Myocarditis is rare.
• The most common viruses causing myocarditis are always changing.
• Myocarditis is most common in infants and teenagers but it has different clinical patterns in each population.
• MRI is becoming the diagnostic tool of choice.
• IVIG frequently is used but good evidence for the therapy is lacking.
• Patients may go home on cardiac medications but have good long-term outcomes.
• Patients must have a 6-month restriction on competitive sports after diagnosis.

Frank Han, MD, a pediatric cardiologist at OSF Medical Center and Children’s Hospital of Illinois in Peoria, said he found the most helpful parts of Dr. Butts’ presentation to be the diagnosis and triage of myocarditis in the major age groups.

“Myocarditis can have variable presentations, and its cause may influence how the myocarditis behaves,” Dr. Han said. Pediatric cardiologists, he said, are uniquely positioned to triage and diagnose myocarditis.
 

Epidemiology and presentation

Just 0.05% of admissions from 28.6 million U.S. pediatric ED visits every year are for myocarditis, Dr. Butts said. While viruses are the most common cause of myocarditis, bacterial infections and noninfectious causes, including hypersensitivity reactions, systemic disorders, and toxic substances, can also cause the condition. The dominant viruses causing myocarditis have shifted over the years as well. Coxsackie B was the most common cause in the 1980s, but adenovirus became more common in the 1990s and parvovirus B19 in the 2000s. Why some kids develop myocarditis while others don’t is unclear, but the host-immune response to the virus likely plays an important role.

Research has shown two substantial spikes in the incidence of myocarditis children: infants under 2 years old and teens aged 14-19. Although myocarditis refers to any inflammation of myocardium not caused by ischemia, the signs, symptoms, and lab results vary according to patient’s age group. The only constant is that diaphoresis is rare across all ages.

Infants are more likely to show respiratory distress (68%) and an enlarged liver (40%) but can also present with gastrointestinal symptoms (24%). Vomiting without fever or diarrhea should arouse clinical suspicion of myocarditis in infants, although fever and diarrhea can occur.

In young children, who have the lowest incidence, fatigue presents in about one-third, with 20% presenting with chest pain and 20% with hepatomegaly. The most common symptom in teens by far (80%) is chest pain. About one-third also have respiratory distress but gastrointestinal symptoms are less common (20%).

When should a clinician suspect myocarditis in a teen presenting with chest pain? “If the chest pain is reproducible and if you can localize it, they don’t need further evaluation,” Dr. Butts said. “After that, it’s a lot about the history.”

In terms of lab results, ventricular function measured by brain natriuretic peptide is significantly depressed in infants and young children but often near normal in teens. Inflammatory markers (C-reactive protein) tend to be low in infants but elevated in young children and teens. And troponin levels, denoting myocardial injury, are minimal in infants and young children but elevated in teens. Median ejection fraction on echocardiograms, about 55% in normal hearts, will often be low in infants and young children, around 30%-33%, but is near normal (54%) in teens.
 

Diagnosis and management

Cardiac MRI increasingly has been replacing endomyocardial biopsy for diagnosis, with MRI exceeding biopsy use between 2009 and 2010, Dr. Butts said. The advantage of endomyocardial biopsy is that it’s specific, if not very sensitive. The test is invasive, however, requiring sedation and carrying the risk of tricuspid injury. The most common finding on cardiac MRI is late gadolinium enhancement (80%) while early gadolinium enhancement is less common (55%).

Although Dr. Butts mentioned the Dallas diagnostic criteria from 1987, he advocated for the more recent Lake Louise Criteria, which require clinical suspicion of myocarditis and at least two of three findings on MRI: T2-weighted myocardial abnormalities, T1 early or late gadolinium enhancement, or regional wall motion abnormalities or evidence of pericarditis

Point-of-care ultrasound can be useful for detecting myocarditis, but its success depends on whether the user can pick up on the subtle changes in ventricular function. “Just because someone has a point-of-care ultrasound that’s normal or thought to be normal, it shouldn’t rule out the diagnosis,” he said.

Learning the etiology of viral myocarditis often is difficult, and etiology doesn’t affect management of the condition, Dr. Butts said. Even in cases of myocarditis confirmed by biopsy, the virus may be identified in only about 60%-70% of cases with myocardial polymerase chain reaction. In clinical cases, the virus can be determined only about 25%-30% of the time with serum PCR.

Prognosis is usually good, with 80%-90% of children and teens going home transplant free despite most arriving critically ill and 50%-80% initially being admitted to ICU. Two-thirds of those discharged go home with heart failure medications, but only one in six are readmitted within a year.

The strongest risk factors for poor prognosis are younger age and being critically ill at presentation but other risk factors include female sex, poor ventricular function, poor perfusion on exam, increased dilation on echocardiogram, and a need for ECMO or inotropes or mechanical ventilation.

That said, Dr. Butts cautioned attendees not to ignore normal function. In one study of 171 patients, among 75 who presented with normal function, 15% went home with inotropes, 12% required mechanical ventilation, 9% had arrhythmia, and 5% needed extracorporeal membrane oxygenation.

A big question in treatment is whether to give IVIG or not and the evidence is murky, Dr. Butts said. He reviewed a couple studies on IVIG, including one that suggested better ventricular functional recovery with the treatment but those who received IVIG were also more likely to be on an ACE inhibitor.

“Was it the ACE inhibitor or was it IVIG? We don’t know,” he said. Different cardiologists may give different opinions on IVIG. “It has nothing to do with the actual evidence behind it.”

IVIG has drawbacks: It’s very expensive and it involves risks that include serum sickness and interstitial nephritis.

“Pediatricians typically aren’t going to directly decide on giving or not giving IVIG,” Dr. Han said. “Typically, the ultimate choice comes from a group discussion between the hospital cardiologist – perhaps the hospitalist pediatrician if they are involved – and the family. We acknowledge the ambiguity of the evidence and decide based upon the severity of the initial disease process.”
 

Return to competitive sports; Follow-up critical

Experts are much more confident, however, about when teens admitted with viral myocarditis can return to competitive sports. But Dr. Butts said he suspects the guidelines for these children aren’t followed as closely as they should be. The American Heart Association recommends waiting 6 months after discharge and ensuring the athlete has a normal echocardiogram, Holter monitoring, and stress test.

“It’s incredibly important to have them come back and see the cardiologist 6 months after admission,” Dr. Butts said. “The only patient I’ve ever had who died 6-7 months post myocarditis is somebody who, during their stress test, had increasing ventricular ectopy. I told him not to do sports. He didn’t listen to me and unfortunately passed away – I’m assuming from arrhythmia.”
 

COVID and vaccine-associated myocarditis

Vaccine-associated myocarditis is substantially milder than viral myocarditis, Dr. Butts said. A small study from a single center in Atlanta found that ejection fraction at admission was normal, around 56%, in those with vaccine-associated myocarditis, compared with 45% with non-COVID viral myocarditis and 50% with multisystem inflammatory syndrome in children or myocarditis from COVID-19. All patients with vaccine-associated myocarditis had normal function at discharge, compared with 73% of those with viral myocarditis and 93% with COVID-associated myocarditis.

While 22% of those with vaccine-associated myocarditis were admitted to the ICU, twice as many (40%) with viral myocarditis were, and three times as many (68%) with COVID-associated myocarditis ended up in intensive care.

Dr. Butts also noted a Morbidity and Mortality Weekly Report from the Centers of Disease Control and Prevention that found teen boys had two to six times greater risk of heart complications after COVID-19 infection than after COVID vaccination.

In terms of direct comparisons, vaccine-related myocarditis occurred about 12-18 times per 100,000 doses for boys ages 5-11 years, compared with cardiac involvement in 93-133 cases out of 100,000 COVID-19 infections. Boys aged 12-17 years experienced 12-21 cases of myocarditis per 100,000 doses of the vaccine, compared with cardiac involvement in 50-64 out of 100,000 infections.

The bottom line, Dr. Butts said, is that cardiac involvement in MIS-C is common, but typically improves by discharge. “Vaccine-associated myocarditis is a mild clinical syndrome that has a very short duration, and, in my opinion, should never lead us to ever advise anybody not to get the vaccine. I’ve had many patients, even patients in their first year post transplant, who have gotten the COVID-19 vaccine and were just fine.”

Dr. Butts acknowledged that talking with families about the risk of myocarditis with the vaccine is challenging. He often starts these conversations by sharing the statistics, but he said relatable stories are the key. He will also relate the statistics to something the parents and teen will understand, whether it’s sports or another comparison. He does recommend that teens who develop vaccine-associated myocarditis complete the series and get the booster. Their chances of developing myocarditis again are extremely low, whereas “the likelihood of them being really ill from COVID-19 is much, much higher.”

Dr. Butts and Dr. Han had no disclosures. The presentation involved no external funding.

Nirmatrelvir/ritonavir (Paxlovid) has been a game changer for high-risk patients with early COVID-19 symptoms but has significant interactions with commonly used cardiovascular medications, a new paper cautions.

COVID-19 patients with cardiovascular disease (CVD) or risk factors such as diabetes, hypertension, and chronic kidney disease are at high risk of severe disease and account for the lion’s share of those receiving Paxlovid. Data from the initial EPIC-HR trial and recent real-world data also suggest they’re among the most likely to benefit from the oral antiviral, regardless of their COVID-19 vaccination status.

“But at the same time, it unfortunately interacts with many very commonly prescribed cardiovascular medications and with many of them in a very clinically meaningful way, which may lead to serious adverse consequences,” senior author Sarju Ganatra, MD, said in an interview. “So, while it’s being prescribed with a good intention to help these people, we may actually end up doing more harm than good.

“We don’t want to deter people from getting their necessary COVID-19 treatment, which is excellent for the most part these days as an outpatient,” he added. “So, we felt the need to make a comprehensive list of cardiac medications and level of interactions with Paxlovid and also to help the clinicians and prescribers at the point of care to make the clinical decision of what modifications they may need to do.”

The paper, published online in the Journal of the American College of Cardiology, details drug-drug interactions with some 80 CV medications including statins, antihypertensive agents, heart failure therapies, and antiplatelet/anticoagulants.

It also includes a color-coded figure denoting whether a drug is safe to coadminister with Paxlovid, may potentially interact and require a dose adjustment or temporary discontinuation, or is contraindicated.

Among the commonly used blood thinners, for example, the paper notes that Paxlovid significantly increases drug levels of the direct oral anticoagulants (DOACs) apixaban, rivaroxaban, edoxaban, and dabigatran and, thus, increases the risk of bleeding.

“It can still be administered, if it’s necessary, but the dose of the DOAC either needs to be reduced or held depending on what they are getting it for, whether they’re getting it for pulmonary embolism or atrial fibrillation, and we adjust for all those things in the table in the paper,” said Dr. Ganatra, from Lahey Hospital and Medical Center, Burlington, Mass.

When the DOAC can’t be interrupted or dose adjusted, however, Paxlovid should not be given, the experts said. The antiviral is safe to use with enoxaparin, a low-molecular-weight heparin, but can increase or decrease levels of warfarin and should be used with close international normalized ratio monitoring.

For patients on antiplatelet agents, clinicians are advised to avoid prescribing nirmatrelvir/ritonavir to those on ticagrelor or clopidogrel unless the agents can be replaced by prasugrel.

Ritonavir – an inhibitor of cytochrome P 450 enzymes, particularly CYP3A4 – poses an increased risk of bleeding when given with ticagrelor, a CYP3A4 substrate, and decreases the active metabolite of clopidogrel, cutting its platelet inhibition by 20%. Although there’s a twofold decrease in the maximum concentration of prasugrel in patients on ritonavir, this does not affect its antiplatelet activity, the paper explains.

Among the lipid-lowering agents, experts suggested temporarily withholding atorvastatin, rosuvastatin, simvastatin, and lovastatin because of an increased risk for myopathy and liver toxicity but say that other statins, fibrates, ezetimibe, and the proprotein convertase subtilisin/kexin type 9 inhibitors evolocumab and alirocumab are safe to coadminister with Paxlovid.

While statins typically leave the body within hours, most of the antiarrhythmic drugs, except for sotalol, are not safe to give with Paxlovid, Dr. Ganatra said. It’s technically not feasible to hold these drugs because most have long half-lives, reaching about 100 days, for example, for amiodarone.

“It’s going to hang around in your system for a long time, so you don’t want to be falsely reassured that you’re holding the drug and it’s going to be fine to go back slowly,” he said. “You need to look for alternative therapies in those scenarios for COVID-19 treatment, which could be other antivirals, or a monoclonal antibody individualized to the patient’s risk.”

Although there’s limited clinical information regarding interaction-related adverse events with Paxlovid, the team used pharmacokinetics and pharmacodynamics data to provide the guidance. Serious adverse events are also well documented for ritonavir, which has been prescribed for years to treat HIV, Dr. Ganatra noted.

The Infectious Disease Society of America also published guidance on the management of potential drug interactions with Paxlovid in May and, earlier in October, the Food and Drug Administration updated its Paxlovid patient eligibility screening checklist.

Still, most prescribers are actually primary care physicians and even pharmacists, who may not be completely attuned, said Dr. Ganatra, who noted that some centers have started programs to help connect primary care physicians with their cardiology colleagues to check on CV drugs in their COVID-19 patients.

“We need to be thinking more broadly and at a system level where the hospital or health care system leverages the electronic health record systems,” he said. “Most of them are sophisticated enough to incorporate simple drug-drug interaction information, so if you try to prescribe someone Paxlovid and it’s a heart transplant patient who is on immunosuppressive therapy or a patient on a blood thinner, then it should give you a warning ... or at least give them a link to our paper or other valuable resources.

“If someone is on a blood thinner and the blood thinner level goes up by ninefold, we can only imagine what we would be dealing with,” Dr. Ganatra said. “So, these interactions should be taken very seriously and I think it’s worth the time and investment.”

The authors reported no relevant financial relationships.

Nirmatrelvir/ritonavir (Paxlovid) has been a game changer for high-risk patients with early COVID-19 symptoms but has significant interactions with commonly used cardiovascular medications, a new paper cautions.

COVID-19 patients with cardiovascular disease (CVD) or risk factors such as diabetes, hypertension, and chronic kidney disease are at high risk of severe disease and account for the lion’s share of those receiving Paxlovid. Data from the initial EPIC-HR trial and recent real-world data also suggest they’re among the most likely to benefit from the oral antiviral, regardless of their COVID-19 vaccination status.

“But at the same time, it unfortunately interacts with many very commonly prescribed cardiovascular medications and with many of them in a very clinically meaningful way, which may lead to serious adverse consequences,” senior author Sarju Ganatra, MD, said in an interview. “So, while it’s being prescribed with a good intention to help these people, we may actually end up doing more harm than good.

“We don’t want to deter people from getting their necessary COVID-19 treatment, which is excellent for the most part these days as an outpatient,” he added. “So, we felt the need to make a comprehensive list of cardiac medications and level of interactions with Paxlovid and also to help the clinicians and prescribers at the point of care to make the clinical decision of what modifications they may need to do.”

The paper, published online in the Journal of the American College of Cardiology, details drug-drug interactions with some 80 CV medications including statins, antihypertensive agents, heart failure therapies, and antiplatelet/anticoagulants.

It also includes a color-coded figure denoting whether a drug is safe to coadminister with Paxlovid, may potentially interact and require a dose adjustment or temporary discontinuation, or is contraindicated.

Full vaccination status against COVID-19 was associated with significantly reduced mortality among critically ill patients with COVID-19 who needed mechanical ventilation, according to results of a study that involved 265 adults.

Although COVID-19 vaccination has been demonstrated to be effective at preventing infection, breakthrough infections occur, write Eirini Grapsa, RN, of Kapodistrian University of Athens Medical School, Greece, and colleagues. The potential protective benefits of vaccination for patients who experience these breakthrough infections, especially cases severe enough to require hospitalization and the need for mechanical ventilation, have not been well studied, the investigators say.

In a study published in JAMA Network Open, the researchers reviewed data from 265 consecutive patients older than 18 years who were admitted to intensive care units at three tertiary care centers with confirmed SARS-CoV-2 infections between June 7, 2021, and Feb. 1, 2022. All patients in the study received invasive mechanical ventilation because of acute respiratory distress syndrome (ARDS). The patients were divided into two groups: 26 patients were in the full vaccination group, and 239 served as control patients. Full vaccination was defined as having completed the primary COVID-19 series more than 14 days but less than 5 months before intubation. The control group included patients who had been fully vaccinated for less than 14 days or more than 5 months, were partially vaccinated, or were not vaccinated. A total of 20 of 26 patients in the full vaccination group received the Pfizer BioNTech BNT162b2 vaccine, as did 25 of the 33 vaccinated patients in the control group.

The median age of the patients overall was 66 years; 36% were women, and 99% were White. Patients in the full vaccination group were more likely to be older and to have comorbidities. The primary outcome was the time from intubation to all-cause mortality.

Overall, mortality was lower among the patients with full vaccination status than among those in the control group (61.5% vs. 68.2%; P = .03). Full vaccination also was associated with lower mortality in sensitivity analyses that included (a) only patients who received an mRNA vaccine in the full vaccination group, and (b) only unvaccinated patients in the control group (hazard ratios, 0.47 and 0.54, respectively).

In a regression model that examined secondary outcomes, the HR was 0.40 for the association between full vaccination and 28-day mortality. No significant differences were seen in length of stay in the intensive care unit (ICU) or length of hospital stay among survivors, nor in the occurrence of bacteremia, use of vasopressors, number of vasopressor-free days, use of continuous kidney replacement therapy (CKRT), number of CKRT-free days, and the number of ventilator-free and ICU-free days.

“Our choice to take time since vaccination into consideration was based on several previous studies indicating that protection against infection from vaccination (specifically with mRNA vaccines, such as BNT162b2, which was administered to 76.9% of patients in the full vaccination group) may decrease over time,” the researchers write.

Oxygenation was higher in the full vaccination group than in the control group on the third day after intubation. Previous studies conducted before the COVID-19 pandemic have shown that oxygenation on the third day after intubation may be more strongly associated with mortality than oxygenation on the day of intubation, the researchers note. Bacteremia was higher among the control patients and could have affected mortality, although the difference between vaccinated patients and control patients was not significant, the researchers add.

The study findings were limited by several factors, including small sample size, which prevented direct comparisons of the effectiveness of different numbers of vaccine doses or vaccine types, the researchers note. Other limitations include selection bias and residual confounding variables, they say.

The results demonstrate an association between full vaccination and lower mortality and suggest that vaccination may benefit patients with COVID-19–related ARDS, beyond the need for mechanical ventilation alone, they say. “These results expand our understanding of the outcomes of patients with breakthrough infections,” they conclude.

The study was supported by a grant to corresponding author Ilias I. Siempos, MD, from the Hellenic Foundation for Research and Innovation. The researchers have disclosed no relevant financial relationships.

The COVID-19 pandemic is driving attention to clean indoor air like never before.

At a White House summit on Oct. 11, leaders from government, industry, and education came together to make a case that low-quality indoor air should warrant the same kind of outrage and action as low-quality water.

“Indoor air is that next frontier when it comes to thinking about public health for humanity,” said Ashish Jha, MD, MPH, who heads the White House COVID response team.

“This once-in-a-century pandemic has given us a moment. A moment when we can drive significant structural changes in the air that we all breathe,” he said.

The threat is immediate, Dr. Jha said, explaining that the return of influenza this year and other circulating respiratory viruses on top of COVID cases could overwhelm the health system.

“We have to bring the burden of respiratory pathogens down and the single biggest structural change we can make as a society is to do for indoor air what we’ve done for water quality,” he said.
 

Recent federal actions

Dr. Jha pointed to White House actions toward that end.

On Oct. 11, the White House launched a new website asking building owners and operators to sign a pledge for clean air and agree to four principles:

• Create an action plan.
• Optimize fresh air ventilation.
• Enhance air filtration and cleaning.
• Communicate with building occupants to increase awareness.

Those who pledge can download a badge to feature on their websites.

In March, the White House launched the Clean Air in Buildings Challenge as a call to action for building owners and operators to improve ventilation, filtration, and facilities for cleaner indoor air.

The government has provided funds that can be used in schools, public buildings, and other locations to improve indoor air quality, including $350 billion for state and local governments and  $122 billion for schools, through the American Rescue Plan.

The Department of Energy is offering one-on-one consultations to schools to drive air quality.
 

Calculate your ‘indoor age’

Joseph Allen, DSc, MPH, director of the Healthy Buildings program and an associate professor at Harvard’s T. H. Chan School of Public Health in Boston, said that the indoor environment has an outsized effect on public health.

He asked people to multiply their age times 0.9 to calculate their “indoor age.”

Dr. Allen, 47, said that for him that number is 42 years spent inside spaces.

When most people realize they spend 90% of their time indoors, a startling possibility comes into play: “The person who manages your building has a greater impact on your health than your doctor,” he said. “Think about that.”

Dr. Allen led a team that published a report on four strategies every building should pursue to reduce COVID and other respiratory illnesses:

• Give every building a tune-up. “We do this for our cars, we don’t do it for our buildings,” Dr. Allen said.
• Maximize outdoor ventilation.
• Upgrade filtration. “We need to move away from filters designed to protect equipment to filters designed to protect people. MERV 13 is the new minimum.”
• Supplement with portable air cleaners.

It’s not a complete list, he said; “It’s where you should start.”
 

Indoor air innovations

Others are suggesting innovations in schools and businesses.

Denver (Colorado) Public School Superintendent Alex Marrero, EdD, said that the system is implementing an air quality dashboard to display performance on factors such as carbon dioxide levels, particulate matter, and volatile organic compounds in schools.

“When you’re deciding what school you’re going to visit or even enroll in, you’ll have a snapshot of what we’re able to gather. Hopefully we’ll have something up before the end of the school year,” he said.

Shelly L. Miller, PhD, professor of mechanical engineering in the environmental engineering program at the University of Colorado Boulder, said that germicidal ultraviolet disinfection, used currently in water quality, holds promise for cleaning the COVID virus and other pathogens from indoor air.

“We were looking at germicidal UV way back in the 2000s for an outbreak of tuberculosis. We continue to see that it’s effective for measles. Why can’t we put a little more emphasis on these technologies?” Dr. Miller asks, acknowledging that there is a lack of expertise in designing such systems and in training and maintenance.

“It’s not for everybody, but it’s for a lot more places than we’re using it now,” she said.
 

Legislation like 1970 Clean Air Act needed?

Richard Corsi, PhD, dean of the College of Engineering at the University of California, Davis, said that education is lacking on the subject and indoor air quality is taught as a class in only a few universities, including his own.

He suggested starting the education even much earlier, in high school biology, chemistry, and physics courses.

Relative to other fields, he said, research and funding for indoor air quality “has been anemic.”

Work on outdoor air quality has seen dramatic improvements over the years because of the 52-year-old Clean Air Act, he noted.

“We need something akin to the Clean Air Act for indoor air quality,” Dr. Corsi said.

The speakers declared no relevant financial relationships.

“We have to bring the burden of respiratory pathogens down and the single biggest structural change we can make as a society is to do for indoor air what we’ve done for water quality,” he said.
 

Recent federal actions

Dr. Jha pointed to White House actions toward that end.

On Oct. 11, the White House launched a new website asking building owners and operators to sign a pledge for clean air and agree to four principles:

• Create an action plan.
• Optimize fresh air ventilation.
• Enhance air filtration and cleaning.
• Communicate with building occupants to increase awareness.

Those who pledge can download a badge to feature on their websites.

In March, the White House launched the Clean Air in Buildings Challenge as a call to action for building owners and operators to improve ventilation, filtration, and facilities for cleaner indoor air.

The government has provided funds that can be used in schools, public buildings, and other locations to improve indoor air quality, including $350 billion for state and local governments and  $122 billion for schools, through the American Rescue Plan.

The Department of Energy is offering one-on-one consultations to schools to drive air quality.
 

Calculate your ‘indoor age’

Joseph Allen, DSc, MPH, director of the Healthy Buildings program and an associate professor at Harvard’s T. H. Chan School of Public Health in Boston, said that the indoor environment has an outsized effect on public health.

He asked people to multiply their age times 0.9 to calculate their “indoor age.”

Dr. Allen, 47, said that for him that number is 42 years spent inside spaces.

When most people realize they spend 90% of their time indoors, a startling possibility comes into play: “The person who manages your building has a greater impact on your health than your doctor,” he said. “Think about that.”

Dr. Allen led a team that published a report on four strategies every building should pursue to reduce COVID and other respiratory illnesses:

• Give every building a tune-up. “We do this for our cars, we don’t do it for our buildings,” Dr. Allen said.
• Maximize outdoor ventilation.
• Upgrade filtration. “We need to move away from filters designed to protect equipment to filters designed to protect people. MERV 13 is the new minimum.”
• Supplement with portable air cleaners.

It’s not a complete list, he said; “It’s where you should start.”
 

Indoor air innovations

Others are suggesting innovations in schools and businesses.

Denver (Colorado) Public School Superintendent Alex Marrero, EdD, said that the system is implementing an air quality dashboard to display performance on factors such as carbon dioxide levels, particulate matter, and volatile organic compounds in schools.

“When you’re deciding what school you’re going to visit or even enroll in, you’ll have a snapshot of what we’re able to gather. Hopefully we’ll have something up before the end of the school year,” he said.

Shelly L. Miller, PhD, professor of mechanical engineering in the environmental engineering program at the University of Colorado Boulder, said that germicidal ultraviolet disinfection, used currently in water quality, holds promise for cleaning the COVID virus and other pathogens from indoor air.

“We were looking at germicidal UV way back in the 2000s for an outbreak of tuberculosis. We continue to see that it’s effective for measles. Why can’t we put a little more emphasis on these technologies?” Dr. Miller asks, acknowledging that there is a lack of expertise in designing such systems and in training and maintenance.

“It’s not for everybody, but it’s for a lot more places than we’re using it now,” she said.
 

Legislation like 1970 Clean Air Act needed?

Richard Corsi, PhD, dean of the College of Engineering at the University of California, Davis, said that education is lacking on the subject and indoor air quality is taught as a class in only a few universities, including his own.

He suggested starting the education even much earlier, in high school biology, chemistry, and physics courses.

Relative to other fields, he said, research and funding for indoor air quality “has been anemic.”

Work on outdoor air quality has seen dramatic improvements over the years because of the 52-year-old Clean Air Act, he noted.

“We need something akin to the Clean Air Act for indoor air quality,” Dr. Corsi said.

The speakers declared no relevant financial relationships.

The COVID-19 pandemic is driving attention to clean indoor air like never before.

At a White House summit on Oct. 11, leaders from government, industry, and education came together to make a case that low-quality indoor air should warrant the same kind of outrage and action as low-quality water.

“Indoor air is that next frontier when it comes to thinking about public health for humanity,” said Ashish Jha, MD, MPH, who heads the White House COVID response team.

“This once-in-a-century pandemic has given us a moment. A moment when we can drive significant structural changes in the air that we all breathe,” he said.

A recent piece in The Economist about masks, and how at least half of the people in Japan are planning to continue to use masks indefinitely (where there was never a mandate), prompts a deeper look into what has been the secret of Japan’s extraordinary success in the pandemic. Over time it has the least cumulative deaths per capita of any major country in the world. That’s without a zero-Covid policy or any national lockdowns, which is why I have not included China as a comparator.

Before we get into that data, let’s take a look at the age pyramids for Japan and the United States. The No. 1 risk factor for death from COVID-19 is advanced age, and you can see that in Japan about 25% of the population is age 65 and older, whereas in the United States that proportion is substantially reduced at 15%. Sure there are differences in comorbidities such as obesity and diabetes, but there is also the trade-off of a much higher population density in Japan.

Besides masks, which were distributed early on by the government to the population in Japan, there was the “Avoid the 3Cs” cluster-busting strategy, widely disseminated in the spring of 2020, leveraging Pareto’s 80-20 principle, long before there were any vaccines available. For a good portion of the pandemic, the Ministry of Foreign Affairs of Japan maintained a strict policy for border control, which while hard to quantify, may certainly have contributed to its success.

Besides these factors, once vaccines became available, Japan got the population with the primary series to 83% rapidly, even after getting a late start by many months compared with the United States, which has peaked at 68%. That’s a big gap.

But that gap got much worse when it came to boosters. Ninety-five percent of Japanese eligible compared with 40.8% of Americans have had a booster shot. Of note, that 95% in Japan pertains to the whole population. In the United States the percentage of people age 65 and older who have had two boosters is currently only 42%. I’ve previously reviewed the important lifesaving impact of two boosters among people age 65 and older from five independent studies during Omicron waves throughout the world.

Now let’s turn to cumulative fatalities in the two countries. There’s a huge, nearly ninefold difference, per capita. Using today’s Covid-19 Dashboard, there are cumulatively 45,533 deaths in Japan and 1,062,560 American deaths. That translates to 1 in 2,758 people in Japan compared with 1 in 315 Americans dying of COVID.

And if we look at excess mortality instead of confirmed COVID deaths, that enormous gap doesn’t change.

Obviously it would be good to have data for other COVID outcomes, such as hospitalizations, ICUs, and Long COVID, but they are not accessible.

Comparing Japan, the country that has fared the best, with the United States, one of the worst pandemic outcome results, leaves us with a sense that Prof Ian MacKay’s “Swiss cheese model” is the best explanation. It’s not just one thing. Masks, consistent evidence-based communication (3Cs) with attention to ventilation and air quality, and the outstanding uptake of vaccines and boosters all contributed to Japan’s success.

There is another factor to add to that model – Paxlovid. Its benefit of reducing hospitalizations and deaths for people over age 65 is unquestionable.

That’s why I had previously modified the Swiss cheese model to add Paxlovid.

But in the United States, where 15% of the population is 65 and older, they account for over 75% of the daily death toll, still in the range of 400 per day. Here, with a very high proportion of people age 65 and older left vulnerable without boosters, or primary vaccines, Paxlovid is only being given to less than 25% of the eligible (age 50+), and less people age 80 and older are getting Paxlovid than those age 45. The reasons that doctors are not prescribing it – worried about interactions for a 5-day course and rebound – are not substantiated.

Bottom line: In the United States we are not protecting our population anywhere near as well as Japan, as grossly evident by the fatalities among people at the highest risk. There needs to be far better uptake of boosters and use of Paxlovid in the age 65+ group, but the need for amped up protection is not at all restricted to this age subgroup. Across all age groups age 18 and over there is an 81% reduction of hospitalizations with two boosters with the most updated CDC data available, through the Omicron BA.5 wave.

No less the previous data through May 2022 showing protection from death across all ages with two boosters

And please don’t forget that around the world, over 20 million lives were saved, just in 2021, the first year of vaccines.

We can learn so much from a model country like Japan. Yes, we need nasal and variant-proof vaccines to effectively deal with the new variants that are already getting legs in places like XBB in Singapore and ones not on the radar yet. But right now we’ve got to do far better for people getting boosters and, when a person age 65 or older gets COVID, Paxlovid. Take a look at the Chris Hayes video segment when he pleaded for Americans to get a booster shot. Every day that vaccine waning of the U.S. population exceeds the small percentage of people who get a booster, our vulnerability increases. If we don’t get that on track, it’s likely going to be a rough winter ahead.

Headache as a symptom of COVID-19 could help predict survival for inpatients with the disease, according to recent research published in the journal Headache.

In the systematic review and meta-analysis, Víctor J. Gallardo, MSc, of the headache and neurologic pain research group, Vall d’Hebron Research Institute at the Universitat Autònoma de Barcelona, and colleagues performed a search of studies in PubMed involving headache symptoms, disease survival, and inpatient COVID-19 cases published between December 2019 and December 2020. Overall, 48 studies were identified, consisting of 43,169 inpatients with COVID-19. Using random-effects pooling models, Mr. Gallardo and colleagues estimated the prevalence of headache for inpatients who survived COVID-19, compared with those who did not survive.

Within those studies, 35,132 inpatients (81.4%) survived, while 8,037 inpatients (18.6%) died from COVID-19. The researchers found that inpatients with COVID-19 and headache symptoms had a significantly higher survival rate compared with inpatients with COVID-19 without headache symptoms (risk ratio, 1.90; 95% confidence interval, 1.46-2.47; P < .0001). There was an overall pooled prevalence of headache as a COVID-19 symptom in 10.4% of inpatients, which was reduced to an estimated pooled prevalence of 9.7% after the researchers removed outlier studies in a sensitivity analysis.

Other COVID-19 symptoms that led to improved rates of survival among inpatients were anosmia (RR, 2.94; 95% CI, 1.94-4.45) and myalgia (RR, 1.57; 95% CI, 1.34-1.83) as well as nausea or vomiting (RR, 1.41; 95% CI, 1.08-1.82), while symptoms such as dyspnea, diabetes, chronic liver diseases, chronic respiratory diseases, and chronic kidney diseases were more likely to increase the risk of dying from COVID-19.

The researchers noted several limitations in their meta-analysis that may make their findings less generalizable to future SARS-CoV-2 variants, such as including only studies that were published before COVID-19 vaccines were available and before more infectious SARS-CoV-2 variants like the B.1.617.2 (Delta) variant emerged. They also included studies where inpatients were not tested for COVID-19 because access to testing was not widely available.

“Our meta-analysis points toward a novel possibility: Headache arising secondary to an infection is not a ‘nonspecific’ symptom, but rather it may be a marker of enhanced likelihood of survival. That is, we find that patients reporting headache in the setting of COVID-19 are at reduced risk of death,” Mr. Gallardo and colleagues wrote.
 

More data needed on association between headache and COVID-19

While headache appeared to affect a small proportion of overall inpatients with COVID-19, the researchers noted this might be because individuals with COVID-19 and headache symptoms are less likely to require hospitalization or a visit to the ED. Another potential explanation is that “people with primary headache disorders, including migraine, may be more likely to report symptoms of COVID-19, but they also may be relatively less likely to experience a life-threatening COVID-19 disease course.”

The researchers said this potential association should be explored in future studies as well as in other viral infections or postviral syndromes such as long COVID. “Defining specific headache mechanisms that could enhance survival from viral infections represents an opportunity for the potential discovery of improved viral therapeutics, as well as for understanding whether, and how, primary headache disorders may be adaptive.”

In a comment, Morris Levin, MD, director of the University of California San Francisco Headache Center, said the findings “of this very thought-provoking review suggest that reporting a headache during a COVID-19 infection seems to be associated with better recovery in hospitalized patients.”

Dr. Levin, who was not involved with the study, acknowledged the researchers’ explanation for the overall low rate of headache in these inpatients as one possible explanation.

“Another could be that sick COVID patients were much more troubled by other symptoms like respiratory distress, which overshadowed their headache symptoms, particularly if they were very ill or if the headache pain was of only mild to moderate severity,” he said. “That could also be an alternate explanation for why less dangerously ill hospitalized patients seemed to have more headaches.”

One limitation he saw in the meta-analysis was how clearly the clinicians characterized headache symptoms in each reviewed study. Dr. Levin suggested a retrospective assessment of premorbid migraine history in hospitalized patients with COVID-19, including survivors and fatalities, might have helped clarify this issue. “The headaches themselves were not characterized so drawing conclusions regarding migraine is challenging.”

Dr. Levin noted it is still not well understood how acute and persistent headaches and other neurological symptoms like mental fog occur in patients with COVID-19. We also do not fully understand the natural history of post-COVID headaches and other neurologic sequelae and the management options for acute and persistent neurological sequelae.

Three authors reported personal and institutional relationships in the form of grants, consultancies, speaker’s bureau positions, guidelines committee member appointments, and editorial board positions for a variety of pharmaceutical companies, agencies, societies, and other organizations. Mr. Gallardo reported no relevant financial disclosures. Dr. Levin reported no relevant financial disclosures.

Other COVID-19 symptoms that led to improved rates of survival among inpatients were anosmia (RR, 2.94; 95% CI, 1.94-4.45) and myalgia (RR, 1.57; 95% CI, 1.34-1.83) as well as nausea or vomiting (RR, 1.41; 95% CI, 1.08-1.82), while symptoms such as dyspnea, diabetes, chronic liver diseases, chronic respiratory diseases, and chronic kidney diseases were more likely to increase the risk of dying from COVID-19.

The researchers noted several limitations in their meta-analysis that may make their findings less generalizable to future SARS-CoV-2 variants, such as including only studies that were published before COVID-19 vaccines were available and before more infectious SARS-CoV-2 variants like the B.1.617.2 (Delta) variant emerged. They also included studies where inpatients were not tested for COVID-19 because access to testing was not widely available.

“Our meta-analysis points toward a novel possibility: Headache arising secondary to an infection is not a ‘nonspecific’ symptom, but rather it may be a marker of enhanced likelihood of survival. That is, we find that patients reporting headache in the setting of COVID-19 are at reduced risk of death,” Mr. Gallardo and colleagues wrote.
 

More data needed on association between headache and COVID-19

While headache appeared to affect a small proportion of overall inpatients with COVID-19, the researchers noted this might be because individuals with COVID-19 and headache symptoms are less likely to require hospitalization or a visit to the ED. Another potential explanation is that “people with primary headache disorders, including migraine, may be more likely to report symptoms of COVID-19, but they also may be relatively less likely to experience a life-threatening COVID-19 disease course.”

The researchers said this potential association should be explored in future studies as well as in other viral infections or postviral syndromes such as long COVID. “Defining specific headache mechanisms that could enhance survival from viral infections represents an opportunity for the potential discovery of improved viral therapeutics, as well as for understanding whether, and how, primary headache disorders may be adaptive.”

In a comment, Morris Levin, MD, director of the University of California San Francisco Headache Center, said the findings “of this very thought-provoking review suggest that reporting a headache during a COVID-19 infection seems to be associated with better recovery in hospitalized patients.”

Dr. Levin, who was not involved with the study, acknowledged the researchers’ explanation for the overall low rate of headache in these inpatients as one possible explanation.

“Another could be that sick COVID patients were much more troubled by other symptoms like respiratory distress, which overshadowed their headache symptoms, particularly if they were very ill or if the headache pain was of only mild to moderate severity,” he said. “That could also be an alternate explanation for why less dangerously ill hospitalized patients seemed to have more headaches.”

One limitation he saw in the meta-analysis was how clearly the clinicians characterized headache symptoms in each reviewed study. Dr. Levin suggested a retrospective assessment of premorbid migraine history in hospitalized patients with COVID-19, including survivors and fatalities, might have helped clarify this issue. “The headaches themselves were not characterized so drawing conclusions regarding migraine is challenging.”

Dr. Levin noted it is still not well understood how acute and persistent headaches and other neurological symptoms like mental fog occur in patients with COVID-19. We also do not fully understand the natural history of post-COVID headaches and other neurologic sequelae and the management options for acute and persistent neurological sequelae.

Headache as a symptom of COVID-19 could help predict survival for inpatients with the disease, according to recent research published in the journal Headache.

In the systematic review and meta-analysis, Víctor J. Gallardo, MSc, of the headache and neurologic pain research group, Vall d’Hebron Research Institute at the Universitat Autònoma de Barcelona, and colleagues performed a search of studies in PubMed involving headache symptoms, disease survival, and inpatient COVID-19 cases published between December 2019 and December 2020. Overall, 48 studies were identified, consisting of 43,169 inpatients with COVID-19. Using random-effects pooling models, Mr. Gallardo and colleagues estimated the prevalence of headache for inpatients who survived COVID-19, compared with those who did not survive.

Within those studies, 35,132 inpatients (81.4%) survived, while 8,037 inpatients (18.6%) died from COVID-19. The researchers found that inpatients with COVID-19 and headache symptoms had a significantly higher survival rate compared with inpatients with COVID-19 without headache symptoms (risk ratio, 1.90; 95% confidence interval, 1.46-2.47; P < .0001). There was an overall pooled prevalence of headache as a COVID-19 symptom in 10.4% of inpatients, which was reduced to an estimated pooled prevalence of 9.7% after the researchers removed outlier studies in a sensitivity analysis.

About 1 in 20 people with long COVID continue to live with symptoms at 18 months, and another 42% reported only some improvement in their health and wellbeing in the same time frame, a large study out of Scotland found.

Multiple studies are evaluating people with long COVID in the hopes of figuring out why some people experience debilitating symptoms long after their primary infection ends and others either do not or recover more quickly. 

This current study is notable for its large size – 96,238 people. Researchers checked in with participants at 6, 12, and 18 months, and included a group of people never infected with the coronavirus to help investigators make a stronger case.

“A lot of the symptoms of long COVID are nonspecific and therefore can occur in people never infected,” says senior study author Jill P. Pell, MD, head of the School of Health and Wellbeing at the University of Glasgow in Scotland. 
 

Ruling out coincidence

This study shows that people experienced a wide range of symptoms after becoming infected with COVID-19 at a significantly higher rate than those who were never infected, “thereby confirming that they were genuinely associated with COVID and not merely a coincidence,” she said. 

Among 21,525 people who had COVID-19 and had symptoms, tiredness, headache and muscle aches or muscle weakness were the most common ongoing symptoms. 

Loss of smell was almost nine times more likely in this group compared to the never-infected group in one analysis where researchers controlled for other possible factors. The risk for loss of taste was almost six times greater, followed by risk of breathlessness at three times higher. 

Long COVID risk was highest after a severe original infection and among older people, women, Black, and South Asian populations, people with socioeconomic disadvantages, and those with more than one underlying health condition.

Adding up the 6% with no recovery after 18 months and 42% with partial recovery means that between 6 and 18 months following symptomatic coronavirus infection, almost half of those infected still experience persistent symptoms.
 

Vaccination validated

On the plus side, people vaccinated against COVID-19 before getting infected had a lower risk for some persistent symptoms. In addition, Dr. Pell and colleagues found no evidence that people who experienced asymptomatic infection were likely to experience long COVID symptoms or challenges with activities of daily living. 

The findings of the Long-COVID in Scotland Study (Long-CISS) were published in the journal Nature Communications.
 

‘More long COVID than ever before’

“Unfortunately, these long COVID symptoms are not getting better as the cases of COVID get milder,” said Thomas Gut, DO, medical director for the post-COVID recovery program at Staten Island (N.Y.) University Hospital. “Quite the opposite – this infection has become so common in a community because it’s so mild and spreading so rapidly that we’re seeing more long COVID symptoms than ever before.” 

Although most patients he sees with long COVID resolve their symptoms within 3-6 months, “We do see some patients who require short-term disability because their symptoms continue past 6 months and out to 2 years,” said Dr. Gut, a hospitalist at Staten Island University Hospital, a member hospital of Northwell Health.

Patients with fatigue and neurocognitive symptoms “have a very tough time going back to work. Short-term disability gives them the time and finances to pursue specialty care with cardiology, pulmonary, and neurocognitive testing,” he said.
 

Support the whole person

The burden of living with long COVID goes beyond the persistent symptoms. “Long COVID can have wide-ranging impacts – not only on health but also quality of life and activities of daily living [including] work, mobility, self-care and more,” Dr. Pell said. “So, people with long COVID need support relevant to their individual needs and this may extend beyond the health care sector, for example including social services, school or workplace.”

Still,  Lisa Penziner, RN, founder of the COVID Long Haulers Support Group in Westchester and Long Island, N.Y., said while people with the most severe cases of COVID-19 tended to have the worst long COVID symptoms, they’re not the only ones. 

“We saw many post-COVID members who had mild cases and their long-haul symptoms were worse weeks later than the virus itself,” said Md. Penziner. 

She estimates that 80%-90% of her support group members recover within 6 months. “However, there are others who were experiencing symptoms for much longer.”

Respiratory treatment, physical therapy, and other follow-up doctor visits are common after 6 months, for example. 

“Additionally, there is a mental health component to recovery as well, meaning that the patient must learn to live while experiencing lingering, long-haul COVID symptoms in work and daily life,” said Ms. Penziner, director of special projects at North Westchester Restorative Therapy & Nursing. 

In addition to ongoing medical care, people with long COVID need understanding, she said.

“While long-haul symptoms do not happen to everyone, it is proven that many do experience long-haul symptoms, and the support of the community in understanding is important.”
 

Limitations of the study

Dr. Pell and colleagues noted some strengths and weaknesses to their study. For example, “as a general population study, our findings provide a better indication of the overall risk and burden of long COVID than hospitalized cohorts,” they noted. 

Also, the Scottish population is 96% White, so other long COVID studies with more diverse participants are warranted. 

Another potential weakness is the response rate of 16% among those invited to participate in the study, which Dr. Pell and colleagues addressed: “Our cohort included a large sample (33,281) of people previously infected and the response rate of 16% overall and 20% among people who had symptomatic infection was consistent with previous studies that have used SMS text invitations as the sole method of recruitment.”

“We tell patients this should last 3-6 months, but some patients have longer recovery periods,” Dr. Gut said. “We’re here for them. We have a lot of services available to help get them through the recovery process, and we have a lot of options to help support them.”

“What we found most helpful is when there is peer-to-peer support, reaffirming to the member that they are not alone in the long-haul battle, which has been a major benefit of the support group,” Ms. Penziner said.

Nearly two-thirds of people who had persistent COVID-19 symptoms during the first 2 years of the pandemic were women, according to a new study published in JAMA.

The global study also found that about 6% of people with symptomatic infections had long COVID in 2020 and 2021. The risk for long COVID seemed to be greater among those who needed hospitalization, especially those who needed intensive care.

“Quantifying the number of individuals with long COVID may help policy makers ensure adequate access to services to guide people toward recovery, return to the workplace or school, and restore their mental health and social life,” the researchers wrote.

The study team, which included dozens of researchers across nearly every continent, analyzed data from 54 studies and two databases for more than 1 million patients in 22 countries who had symptomatic COVID infections in 2020 and 2021. They looked at three long COVID symptom types: persistent fatigue with bodily pain or mood swings, ongoing respiratory problems, and cognitive issues. The study included people aged 4-66.

Overall, 6.2% of people reported one of the long COVID symptom types, including 3.7% with ongoing respiratory problems, 3.2% with persistent fatigue and bodily pain or mood swings, and 2.2% with cognitive problems. Among those with long COVID, 38% of people reported more than one symptom cluster.

At 3 months after infection, long COVID symptoms were nearly twice as common in women who were at least 20 years old at 10.6%, compared with men who were at least 20 years old at 5.4%.

Children and teens appeared to have lower risks of long COVID. About 2.8% of patients under age 20 with symptomatic infection developed long-term issues.

The estimated average duration of long COVID symptoms was 9 months among hospitalized patients and 4 months among those who weren’t hospitalized. About 15% of people with long COVID symptoms 3 months after the initial infection continued to have symptoms at 12 months.

The study was largely based on detailed data from ongoing COVID-19 studies in the United States, Austria, the Faroe Islands, Germany, Iran, Italy, the Netherlands, Russia, Sweden, and Switzerland, according to UPI. It was supplemented by published data and research conducted as part of the Global Burden of Diseases, Injuries and Risk Factors Study. The dozens of researchers are referred to as “Global Burden of Disease Long COVID Collaborators.”

The study had limitations, the researchers said, including the assumption that long COVID follows a similar course in all countries. Additional studies may show how long COVID symptoms and severity may vary in different countries and continents.

Ultimately, ongoing studies of large numbers of people with long COVID could help scientists and public health officials understand risk factors and ways to treat the debilitating condition, the study authors wrote, noting that “postinfection fatigue syndrome” has been reported before, namely during the 1918 flu pandemic, after the SARS outbreak in 2003, and after the Ebola epidemic in West Africa in 2014.

“Similar symptoms have been reported after other viral infections, including the Epstein-Barr virus, mononucleosis, and dengue, as well as after nonviral infections such as Q fever, Lyme disease and giardiasis,” they wrote.

Several study investigators reported receiving grants and personal fees from a variety of sources.

“Quantifying the number of individuals with long COVID may help policy makers ensure adequate access to services to guide people toward recovery, return to the workplace or school, and restore their mental health and social life,” the researchers wrote.

The study team, which included dozens of researchers across nearly every continent, analyzed data from 54 studies and two databases for more than 1 million patients in 22 countries who had symptomatic COVID infections in 2020 and 2021. They looked at three long COVID symptom types: persistent fatigue with bodily pain or mood swings, ongoing respiratory problems, and cognitive issues. The study included people aged 4-66.

Overall, 6.2% of people reported one of the long COVID symptom types, including 3.7% with ongoing respiratory problems, 3.2% with persistent fatigue and bodily pain or mood swings, and 2.2% with cognitive problems. Among those with long COVID, 38% of people reported more than one symptom cluster.

At 3 months after infection, long COVID symptoms were nearly twice as common in women who were at least 20 years old at 10.6%, compared with men who were at least 20 years old at 5.4%.

Children and teens appeared to have lower risks of long COVID. About 2.8% of patients under age 20 with symptomatic infection developed long-term issues.

The estimated average duration of long COVID symptoms was 9 months among hospitalized patients and 4 months among those who weren’t hospitalized. About 15% of people with long COVID symptoms 3 months after the initial infection continued to have symptoms at 12 months.

The study was largely based on detailed data from ongoing COVID-19 studies in the United States, Austria, the Faroe Islands, Germany, Iran, Italy, the Netherlands, Russia, Sweden, and Switzerland, according to UPI. It was supplemented by published data and research conducted as part of the Global Burden of Diseases, Injuries and Risk Factors Study. The dozens of researchers are referred to as “Global Burden of Disease Long COVID Collaborators.”

The study had limitations, the researchers said, including the assumption that long COVID follows a similar course in all countries. Additional studies may show how long COVID symptoms and severity may vary in different countries and continents.

Ultimately, ongoing studies of large numbers of people with long COVID could help scientists and public health officials understand risk factors and ways to treat the debilitating condition, the study authors wrote, noting that “postinfection fatigue syndrome” has been reported before, namely during the 1918 flu pandemic, after the SARS outbreak in 2003, and after the Ebola epidemic in West Africa in 2014.

“Similar symptoms have been reported after other viral infections, including the Epstein-Barr virus, mononucleosis, and dengue, as well as after nonviral infections such as Q fever, Lyme disease and giardiasis,” they wrote.

Several study investigators reported receiving grants and personal fees from a variety of sources.

Welcome to Impact Factor, your weekly dose of commentary on a new medical study. I’m Dr. F. Perry Wilson of the Yale School of Medicine.

Have you ever lied about COVID-19?

Before you get upset, before the “how dare you,” I want you to think carefully.

Did you have COVID-19 (or think you did) and not mention it to someone you were going to be with? Did you tell someone you were taking more COVID precautions than you really were? Did you tell someone you were vaccinated when you weren’t? Have you avoided getting a COVID test even though you knew you should have?

A new study, appearing in JAMA Network Open, suggests that nearly half of people have lied about something to do with COVID. And those are just the people who admit it.

Researchers appreciated the fact that public health interventions in COVID are important but are only as good as the percentage of people who actually abide by them. So, they designed a survey to ask the questions that many people don’t want to hear the answer to.

A total of 1,733 participants – 80% of those invited – responded to the survey. By design, approximately one-third of respondents (477) had already had COVID, one-third (499) were vaccinated and not yet infected, and one-third (509) were unvaccinated and not yet infected.

Of those surveyed, 41.6% admitted that they lied about COVID or didn’t adhere to COVID guidelines - a conservative estimate, if you ask me.

Breaking down some of the results, about 20% of people who previously were infected with COVID said they didn’t mention it when meeting with someone. A similar number said they didn’t tell anyone when they were entering a public place. A bit more concerning to me, roughly 20% reported not disclosing their COVID-positive status when going to a health care provider’s office.

About 10% of those who had not been vaccinated reported lying about their vaccination status. That’s actually less than the 15% of vaccinated people who lied and told someone they weren’t vaccinated.

About 17% of people lied about the need to quarantine, and many more broke quarantine rules.

The authors tried to see if certain personal characteristics predicted people who were more likely to lie about COVID-19–related issues. Turns out there was only one thing that predicted honesty: age.

Older people were more honest about their COVID status and COVID habits. Other factors – gender, education, race, political affiliation, COVID-19 conspiracy beliefs, and where you got your COVID information – did not seem to make much of a difference. Why are older people more honest? Because older people take COVID more seriously. And they should; COVID is more severe in older people.

The problem arises, of course, because people who are at lower risk for COVID complications interact with people at higher risk – and in those situations, honesty matters more.

On the other hand, isn’t lying about COVID stuff inevitable? If you know that a positive test means you can’t go to work, and not going to work means you won’t get paid, might you not be more likely to lie about the test? Or not get the test at all?

The authors explored the reasons for dishonesty and they are fairly broad, ranging from the desire for life to feel normal (more than half of people who lied) to not believing that COVID was real (a whopping 30%). Some of the reasons for lying included:

• Wanted life to feel normal (50%).
• Freedom (45%).
• It’s no one’s business (40%).
• COVID isn’t real (30%).

In the end, though, we need to realize that public health recommendations are not going to be universally followed, and people may tell us they are following them when, in fact, they are not.

What this adds is another data point to a trend we’ve seen across the course of the pandemic, a shift from collective to individual responsibility. If you can’t be sure what others are doing in regard to COVID, you need to focus on protecting yourself. Perhaps that shift was inevitable. Doesn’t mean we have to like it.

Weeks after Jeannie Volpe caught COVID-19 in November 2020, she could no longer do her job running sexual assault support groups in Anniston, Ala., because she kept forgetting the details that survivors had shared with her. “People were telling me they were having to revisit their traumatic memories, which isn’t fair to anybody,” the 47-year-old says.

Ms. Volpe has been diagnosed with long-COVID autonomic dysfunction, which includes severe muscle pain, depression, anxiety, and a loss of thinking skills. Some of her symptoms are more commonly known as brain fog, and they’re among the most frequent problems reported by people who have long-term issues after a bout of COVID-19.

Many experts and medical professionals say they haven’t even begun to scratch the surface of what impact this will have in years to come. 

“I’m very worried that we have an epidemic of neurologic dysfunction coming down the pike,” says Pamela Davis, MD, PhD, a research professor at Case Western Reserve University, Cleveland.

In the 2 years Ms. Volpe has been living with long COVID, her executive function – the mental processes that enable people to focus attention, retain information, and multitask – has been so diminished that she had to relearn to drive. One of the various doctors assessing her has suggested speech therapy to help Ms. Volpe relearn how to form words. “I can see the words I want to say in my mind, but I can’t make them come out of my mouth,” she says in a sluggish voice that gives away her condition. 

All of those symptoms make it difficult for her to care for herself. Without a job and health insurance, Ms. Volpe says she’s researched assisted suicide in the states that allow it but has ultimately decided she wants to live. 

“People tell you things like you should be grateful you survived it, and you should; but you shouldn’t expect somebody to not grieve after losing their autonomy, their career, their finances.”

The findings of researchers studying the brain effects of COVID-19 reinforce what people with long COVID have been dealing with from the start. Their experiences aren’t imaginary; they’re consistent with neurological disorders – including myalgic encephalomyelitis, also known as chronic fatigue syndrome, or ME/CFS – which carry much more weight in the public imagination than the term brain fog, which can often be used dismissively.

Studies have found that COVID-19 is linked to conditions such as strokes; seizures; and mood, memory, and movement disorders. 

While there are still a lot of unanswered questions about exactly how COVID-19 affects the brain and what the long-term effects are, there’s enough reason to suggest people should be trying to avoid both infection and reinfection until researchers get more answers.

Worldwide, it’s estimated that COVID-19 has contributed to more than 40 million new cases of neurological disorders, says Ziyad Al-Aly, MD, a clinical epidemiologist and long COVID researcher at Washington University in St. Louis. In his latest study of 14 million medical records of the U.S. Department of Veterans Affairs, the country’s largest integrated health care system, researchers found that regardless of age, gender, race, and lifestyle, people who have had COVID-19 are at a higher risk of getting a wide array of 44 neurological conditions after the first year of infection.

He noted that some of the conditions, such as headaches and mild decline in memory and sharpness, may improve and go away over time. But others that showed up, such as stroke, encephalitis (inflammation of the brain), and Guillain-Barré syndrome (a rare disorder in which the body’s immune system attacks the nerves), often lead to lasting damage. Dr. Al-Aly’s team found that neurological conditions were 7% more likely in those who had COVID-19 than in those who had never been infected. 

What’s more, researchers noticed that compared with control groups, the risk of post-COVID thinking problems was more pronounced in people in their 30s, 40s, and 50s – a group that usually would be very unlikely to have these problems. For those over the age of 60, the risks stood out less because at that stage of life, such thinking problems aren’t as rare.

Another study of the veterans system last year showed that COVID-19 survivors were at a 46% higher risk of considering suicide after 1 year.

“We need to be paying attention to this,” says Dr. Al-Aly.  “What we’ve seen is really the tip of the iceberg.” He worries that millions of people, including youths, will lose out on employment and education while dealing with long-term disabilities – and the economic and societal implications of such a fallout. “What we will all be left with is the aftermath of sheer devastation in some people’s lives,” he says.

Igor Koralnik, MD, chief of neuro-infectious disease and global neurology at Northwestern University, Chicago, has been running a specialized long COVID clinic. His team published a paper in March 2021 detailing what they saw in their first 100 patients. “About half the population in the study missed at least 10 days of work. This is going to have persistent impact on the workforce,” Dr. Koralnik said in a podcast posted on the Northwestern website. “We have seen that not only [do] patients have symptoms, but they have decreased quality of life.”

For older people and their caregivers, the risk of potential neurodegenerative diseases that the virus has shown to accelerate, such as dementia, is also a big concern. Alzheimer’s is already the fifth leading cause of death for people 65 and older. 

In a recent study of more than 6 million people over the age of 65, Dr. Davis and her team at Case Western found the risk of Alzheimer’s in the year after COVID-19 increased by 50%-80%. The chances were especially high for women older than 85.

To date, there are no good treatments for Alzheimer’s, yet total health care costs for long-term care and hospice services for people with dementia topped $300 billion in 2020. That doesn’t even include the related costs to families.

“The downstream effect of having someone with Alzheimer’s being taken care of by a family member can be devastating on everyone,” she says. “Sometimes the caregivers don’t weather that very well.” 

When Dr. Davis’s own father got Alzheimer’s at age 86, her mother took care of him until she had a stroke one morning while making breakfast. Dr. Davis attributes the stroke to the stress of caregiving. That left Dr. Davis no choice but to seek housing where both her parents could get care. 

Looking at the broader picture, Dr. Davis believes widespread isolation, loneliness, and grief during the pandemic, and the disease of COVID-19 itself, will continue to have a profound impact on psychiatric diagnoses. This in turn could trigger a wave of new substance abuse as a result of unchecked mental health problems.

Still, not all brain experts are jumping to worst-case scenarios, with a lot yet to be understood before sounding the alarm. Joanna Hellmuth, MD, a neurologist and researcher at the University of California, San Francisco, cautions against reading too much into early data, including any assumptions that COVID-19 causes neurodegeneration or irreversible damage in the brain. 

Even with before-and-after brain scans by University of Oxford, England, researchers that show structural changes to the brain after infection, she points out that they didn’t actually study the clinical symptoms of the people in the study, so it’s too soon to reach conclusions about associated cognitive problems.

“It’s an important piece of the puzzle, but we don’t know how that fits together with everything else,” says Dr. Hellmuth. “Some of my patients get better. … I haven’t seen a single person get worse since the pandemic started, and so I’m hopeful.”

Worldwide, it’s estimated that COVID-19 has contributed to more than 40 million new cases of neurological disorders, says Ziyad Al-Aly, MD, a clinical epidemiologist and long COVID researcher at Washington University in St. Louis. In his latest study of 14 million medical records of the U.S. Department of Veterans Affairs, the country’s largest integrated health care system, researchers found that regardless of age, gender, race, and lifestyle, people who have had COVID-19 are at a higher risk of getting a wide array of 44 neurological conditions after the first year of infection.

He noted that some of the conditions, such as headaches and mild decline in memory and sharpness, may improve and go away over time. But others that showed up, such as stroke, encephalitis (inflammation of the brain), and Guillain-Barré syndrome (a rare disorder in which the body’s immune system attacks the nerves), often lead to lasting damage. Dr. Al-Aly’s team found that neurological conditions were 7% more likely in those who had COVID-19 than in those who had never been infected. 

What’s more, researchers noticed that compared with control groups, the risk of post-COVID thinking problems was more pronounced in people in their 30s, 40s, and 50s – a group that usually would be very unlikely to have these problems. For those over the age of 60, the risks stood out less because at that stage of life, such thinking problems aren’t as rare.

Another study of the veterans system last year showed that COVID-19 survivors were at a 46% higher risk of considering suicide after 1 year.

“We need to be paying attention to this,” says Dr. Al-Aly.  “What we’ve seen is really the tip of the iceberg.” He worries that millions of people, including youths, will lose out on employment and education while dealing with long-term disabilities – and the economic and societal implications of such a fallout. “What we will all be left with is the aftermath of sheer devastation in some people’s lives,” he says.

Igor Koralnik, MD, chief of neuro-infectious disease and global neurology at Northwestern University, Chicago, has been running a specialized long COVID clinic. His team published a paper in March 2021 detailing what they saw in their first 100 patients. “About half the population in the study missed at least 10 days of work. This is going to have persistent impact on the workforce,” Dr. Koralnik said in a podcast posted on the Northwestern website. “We have seen that not only [do] patients have symptoms, but they have decreased quality of life.”

For older people and their caregivers, the risk of potential neurodegenerative diseases that the virus has shown to accelerate, such as dementia, is also a big concern. Alzheimer’s is already the fifth leading cause of death for people 65 and older. 

In a recent study of more than 6 million people over the age of 65, Dr. Davis and her team at Case Western found the risk of Alzheimer’s in the year after COVID-19 increased by 50%-80%. The chances were especially high for women older than 85.

To date, there are no good treatments for Alzheimer’s, yet total health care costs for long-term care and hospice services for people with dementia topped $300 billion in 2020. That doesn’t even include the related costs to families.

“The downstream effect of having someone with Alzheimer’s being taken care of by a family member can be devastating on everyone,” she says. “Sometimes the caregivers don’t weather that very well.” 

When Dr. Davis’s own father got Alzheimer’s at age 86, her mother took care of him until she had a stroke one morning while making breakfast. Dr. Davis attributes the stroke to the stress of caregiving. That left Dr. Davis no choice but to seek housing where both her parents could get care. 

Looking at the broader picture, Dr. Davis believes widespread isolation, loneliness, and grief during the pandemic, and the disease of COVID-19 itself, will continue to have a profound impact on psychiatric diagnoses. This in turn could trigger a wave of new substance abuse as a result of unchecked mental health problems.

Still, not all brain experts are jumping to worst-case scenarios, with a lot yet to be understood before sounding the alarm. Joanna Hellmuth, MD, a neurologist and researcher at the University of California, San Francisco, cautions against reading too much into early data, including any assumptions that COVID-19 causes neurodegeneration or irreversible damage in the brain. 

Even with before-and-after brain scans by University of Oxford, England, researchers that show structural changes to the brain after infection, she points out that they didn’t actually study the clinical symptoms of the people in the study, so it’s too soon to reach conclusions about associated cognitive problems.

“It’s an important piece of the puzzle, but we don’t know how that fits together with everything else,” says Dr. Hellmuth. “Some of my patients get better. … I haven’t seen a single person get worse since the pandemic started, and so I’m hopeful.”
