The Centers for Disease Control and Prevention and the World Health Organization have dubbed the BA 2.86 variant of COVID-19 as a variant to watch. 

So far, only 26 cases of “Pirola,” as the new variant is being called, have been identified: 10 in Denmark, four each in Sweden and the United States, three in South Africa, two in Portugal, and one each the United Kingdom, Israel, and Canada. BA 2.86 is a subvariant of Omicron, but according to reports from the CDC, the strain has many more mutations than the ones that came before it. 

With so many facts still unknown about this new variant, this news organization asked experts what people need to be aware of as it continues to spread.
 

What is unique about the BA 2.86 variant? 

“It is unique in that it has more than three mutations on the spike protein,” said Purvi S. Parikh, MD, an infectious disease expert at New York University’s Langone Health. The virus uses the spike proteins to enter our cells. 

This “may mean it will be more transmissible, cause more severe disease, and/or our vaccines and treatments may not work as well, as compared to other variants,” she said.
 

What do we need to watch with BA 2.86 going forward? 

“We don’t know if this variant will be associated with a change in the disease severity. We currently see increased numbers of cases in general, even though we don’t yet see the BA.2.86 in our system,” said Heba Mostafa, PhD, director of the molecular virology laboratory at Johns Hopkins Hospital in Baltimore. 

“It is important to monitor BA.2.86 (and other variants) and understand how its evolution impacts the number of cases and disease outcomes,” she said. “We should all be aware of the current increase in cases, though, and try to get tested and be treated as soon as possible, as antivirals should be effective against the circulating variants.” 
 

What should doctors know?

Dr. Parikh said doctors should generally expect more COVID cases in their clinics and make sure to screen patients even if their symptoms are mild.

“We have tools that can be used – antivirals like Paxlovid are still efficacious with current dominant strains such as EG.5,” she said. “And encourage your patients to get their boosters, mask, wash hands, and social distance.”
 

How well can our vaccines fight BA 2.86?

“Vaccine coverage for the BA.2.86 is an area of uncertainty right now,” said Dr. Mostafa. 

In its report, the CDC said scientists are still figuring out how well the updated COVID vaccine works. It’s expected to be available in the fall, and for now, they believe the new shot will still make infections less severe, new variants and all. 

Prior vaccinations and infections have created antibodies in many people, and that will likely provide some protection, Dr. Mostafa said. “When we experienced the Omicron wave in December 2021, even though the variant was distant from what circulated before its emergence and was associated with a very large increase in the number of cases, vaccinations were still protective against severe disease.” 
 

What is the most important thing to keep track of when it comes to this variant?

According to Dr. Parikh, “it’s most important to monitor how transmissible [BA 2.86] is, how severe it is, and if our current treatments and vaccines work.” 

Dr. Mostafa said how well the new variants escape existing antibody protection should also be studied and watched closely. 
 

What does this stage of the virus mutation tell us about where we are in the pandemic?

The history of the coronavirus over the past few years shows that variants with many changes evolve and can spread very quickly, Dr. Mostafa said. “Now that the virus is endemic, it is essential to monitor, update vaccinations if necessary, diagnose, treat, and implement infection control measures when necessary.”

With the limited data we have so far, experts seem to agree that while the variant’s makeup raises some red flags, it is too soon to jump to any conclusions about how easy it is to catch it and the ways it may change how the virus impacts those who contract it.

COVID-19 hospitalizations have been on the rise for weeks as summer nears its end, but how concerned should you be? SARS-CoV-2, the virus behind COVID, continues to evolve and surprise us. So COVID transmission, hospitalization, and death rates can be difficult to predict. 

This news organization turned to the experts for their take on the current circulating virus, asking them to predict if we’ll be masking up again anytime soon, and what this fall and winter might look like, especially now that testing and vaccinations are no longer free of charge.
 

Question 1: Are you expecting an end-of-summer COVID wave to be substantial?

Eric Topol, MD: “This wave won’t likely be substantial and could be more of a ‘wavelet.’ I’m not thinking that physicians are too concerned,” said Dr. Topol, founder and director of Scripps Research Translational Institute in La Jolla, Calif. 

Thomas Gut, DO: “It’s always impossible to predict the severity of COVID waves. Although the virus has generally mutated in ways that favor easier transmission and milder illness, there have been a handful of surprising mutations that were more dangerous and deadly than the preceding strain,” said Dr. Gut, associate chair of medicine at Staten Island University Hospital/Northwell Health in New York.

Robert Atmar, MD: “I’ll start with the caveat that prognosticating for SARS-CoV-2 is a bit hazardous as we remain in unknown territory for some aspects of its epidemiology and evolution,” said Dr. Atmar, a professor of infectious diseases at Baylor College of Medicine in Houston. “It depends on your definition of substantial. We, at least in Houston, are already in the midst of a substantial surge in the burden of infection, at least as monitored through wastewater surveillance. The amount of virus in the wastewater already exceeds the peak level we saw last winter. That said, the increased infection burden has not translated into large increases in hospitalizations for COVID-19. Most persons hospitalized in our hospital are admitted with infection, not for the consequences of infection.”

Stuart Campbell Ray, MD: “It looks like there is a rise in infections, but the proportional rise in hospitalizations from severe cases is lower than in the past, suggesting that folks are protected by the immunity we’ve gained over the past few years through vaccination and prior infections. Of course, we should be thinking about how that applies to each of us – how recently we had a vaccine or COVID-19, and whether we might see more severe infections as immunity wanes,” said Dr. Ray, who is a professor of medicine in the division of infectious diseases at Johns Hopkins University in Baltimore. 

Question 2: Is a return to masks or mask mandates coming this fall or winter?

Dr. Topol: “Mandating masks doesn’t work very well, but we may see wide use again if a descendant of [variant] BA.2.86 takes off.”

Dr. Gut: “It’s difficult to predict if there are any mask mandates returning at any point. Ever since the Omicron strains emerged, COVID has been relatively mild, compared to previous strains, so there probably won’t be any plan to start masking in public unless a more deadly strain appears.”

Dr. Atmar: “I do not think we will see a return to mask mandates this fall or winter for a variety of reasons. The primary one is that I don’t think the public will accept mask mandates. However, I think masking can continue to be an adjunctive measure to enhance protection from infection, along with booster vaccination.”

Dr. Ray: “Some people will choose to wear masks during a surge, particularly in situations like commuting where they don’t interfere with what they’re doing. They will wear masks particularly if they want to avoid infection due to concerns about others they care about, disruption of work or travel plans, or concerns about long-term consequences of repeated COVID-19.”

Question 3: Now that COVID testing and vaccinations are no longer free of charge, how might that affect their use?

Dr. Topol: “It was already low, and this will undoubtedly further compromise their uptake.”

Dr. Gut: “I do expect that testing will become less common now that tests are no longer free. I’m sure there will be a lower amount of detection in patients with milder or asymptomatic disease compared to what we had previously.”

Dr. Atmar: “If there are out-of-pocket costs for the SARS-CoV-2 vaccine, or if the administrative paperwork attached to getting a vaccine is increased, the uptake of SARS-CoV-2 vaccines will likely decrease. It will be important to communicate to the populations targeted for vaccination the potential benefits of such vaccination.”

Dr. Ray: “A challenge with COVID-19, all along, has been disparities in access to care, and this will be worse without public support for prevention and testing. This applies to everyone but is especially burdensome for those who are often marginalized in our health care system and society in general. I hope that we’ll find ways to ensure that people who need tests and vaccinations are able to access them, as good health is in everyone’s interest.”

Question 4: Will the new vaccines against COVID work for the currently circulating variants?

Dr. Topol: “The XBB.1.5 boosters will be out Sept. 14. They should help versus EG.5.1 and FL.1.5.1. The FL.1.5.1 variant is gaining now.”

Dr. Gut: “In the next several weeks, we expect the newer monovalent XBB-based vaccines to be offered that offer good protection against current circulating COVID variants along with the new Eris variant.”

Dr. Atmar: “The vaccines are expected to induce immune responses to the currently circulating variants, most of which are strains that evolved from the vaccine strain. The vaccine is expected to be most effective in preventing severe illness and will likely be less effective in preventing infection and mild illness.”

Dr. Ray: “Yes, the updated vaccine design has a spike antigen (XBB.1.5) nearly identical to the current dominant variant (EG.5). Even as variants change, the boosters stimulate B cells and T cells to help protect in a way that is safer than getting COVID-19 infection.”

Question 5: Is there anything we should watch out for regarding the BA.2.86 variant in particular?

Dr. Topol: “The scenario could change if there are new functional mutations added to it.”

Dr. Gut: “BA.2.86 is still fairly uncommon and does not have much data to directly make any informed guesses. However, in general, people that have been exposed to more recent mutations of the COVID virus have been shown to have more protection from newer upcoming mutations. It’s fair to guess that people that have not had recent infection from COVID, or have not had a recent booster, are at higher risk for being infected by any XBB- or BA.2-based strains.”

Dr. Atmar: BA.2.86 has been designated as a variant under monitoring. We will want to see whether it becomes more common and if there are any unexpected characteristics associated with infection by this variant.”

Dr. Ray: “It’s still rare, but it’s been seen in geographically dispersed places, so it’s got legs. The question is how effectively it will bypass some of the immunity we’ve gained. T cells are likely to remain protective, because they target so many parts of the virus that change more slowly, but antibodies from B cells to spike protein may have more trouble recognizing BA.2.86, whether those antibodies were made to a vaccine or a prior variant.”

The largest study to date of chronic traumatic encephalopathy (CTE) in young athletes shows that 41% had the neurodegenerative disease, caused by repetitive head impacts (RHIs).

Analysis of brain tissue from athletes who were exposed to RHIs and died before the age of 30 revealed neuropathological evidence of shrinkage of the brain and microscopic changes that indicate a breach of the blood-brain barrier. The case series also identified the first known American female athlete with CTE.

Nearly all of those with CTE had a mild form of the disease and 71% played only at the amateur level in youth, high school, or college sports.

“A lot of people think CTE is a result of high-level, professional play such as football, ice hockey, and boxing, but it can affect amateur athletes and can affect people at a young age,” lead author Ann McKee, MD, professor of neurology and pathology and director of the Chronic Traumatic Encephalopathy Center at Boston University, said in an interview.

The findings were published online in JAMA Neurology.
 

A rare look

Brain donation at younger ages is rare, so most of what is known about CTE comes from studies in older athletes.

“We’ve always known that young people could develop this disease early after just amateur high school, youth, and college exposure, but this is the largest study of donor brains at this age,” Dr. McKee said.

The case series included 152 brains of athletes who played contact sports, experienced RHIs, and died before age 30. The tissues are part of the Understanding Neurologic Injury and Traumatic Encephalopathy (UNITE) Brain Bank and were donated between February 2008 and September 2022.

Researchers reviewed the donors’ medical records and conducted retrospective interviews with the donors’ next of kin to assess cognitive symptoms, mood disturbances, and neurobehavioral issues.

Donors died between the ages of 13 and 29 years, 92.8% were male and 73% were White. In 57.2% of the cases, suicide was the cause of death, with no difference between those with or without CTE.

CTE was neuropathologically diagnosed in 41.4% of athletes, using diagnostic criteria developed by the National Institute of Neurological Disorders and Stroke. 

More than 95% had mild CTE. Diagnosis was associated with older age (mean difference, 3.92 years; P < .001) and significantly more years of exposure to contact sports (11.6 vs. 8.8 years).

Among those with CTE, 71.4% played amateur sports, including football (60.9%), soccer (17.2%), hockey (7.8%), and wrestling (7%).

The cohort includes the first known American female athlete with CTE. Recruiting female brain donors has always been a challenge, Dr. McKee said. In this study, females comprised about 7% of the entire cohort and tended to be younger and play fewer years of a sport, compared with their male counterparts. All of that could lower their risk for CTE, Dr. McKee said.

“We don’t have enough brain donations to make any comments about differences between the genders, but we’ve always known that women can develop CTE,” she said. “It’s been reported after domestic violence and in an autistic woman who was a headbanger, so it was just a matter of time before we found our first case.”
 

Early stage of CTE?

Neuropathological analysis revealed neuronal p-tau aggregates in all CTE cases, a hallmark of the disease.

Young athletes with CTE had significantly more ventricular dilatation, suggesting atrophy or shrinkage of the brain, and more cavum septum pellucidum.

“I was surprised that even at this very young age group we could see structural changes to the gross pathology,” Dr. McKee said.

Investigators also found evidence of perivascular macrophages in the deep white matter, a microscopic change that correlated with CTE and years of play and indicates a breach of the blood-brain barrier that could allow pro-inflammatory molecules to enter the brain, setting up a neuroinflammatory response.

“Neuroinflammation is a very early change after repetitive head impacts, as well as in CTE,” Dr. McKee said. “This may be one of the mechanisms by which the inflammation starts, meaning microvascular injury might be an integral part of the pathogenesis of CTE.”
 

A message for clinicians

All athletes had symptoms of mood and neurobehavioral dysfunction common in people with RHIs. There were no significant differences in those clinical symptoms based on CTE diagnosis, which is likely related to the retrospective nature of the clinical evaluations, Dr. McKee said.

While the study leaves many questions about CTE in younger athletes unanswered, there is a message for clinicians and for patients in the findings, she said.

For clinicians, it’s important to note that “this young population of amateur athletes can be very symptomatic, and in all likelihood, a lot of these symptoms are reversible with proper care and management,” Dr. McKee said.

“For individual athletes, it’s important to note that 58% of this cohort did not have CTE, so just because you have these symptoms is not an indication that you have a neurodegenerative disease,” she added.

The study was funded by Andlinger Foundation, the National Football League, Mac Parkman Foundation, National Operating Committee on Standards for Athletic Equipment, and the Nick and Lynn Buoniconti Foundation, World Wrestling Entertainment, Alzheimer’s Association, National Institutes of Health, Concussion Legacy Foundation, U.S. Department of Defense and the U.S. Department of Veterans Affairs.

Severe COVID infections may lead to lasting damage to the immune system, new research finds.

The small study, published in Cell and funded by the National Institutes of Health, details how immune cells were analyzed through blood samples collected from 38 patients recovering from severe COVID and other critical illnesses, and from 19 healthy people. Researchers from Weill Cornell Medicine, New York, and The Jackson Laboratory for Genomic Medicine, Farmington, Conn., found through isolating hematopoietic stem cells that people recovering from severe bouts of COVID had changes to their DNA that were passed down to offspring cells.

The research team, led by Steven Josefowicz, PhD, of Weill Cornell’s pathology department, and Duygu Ucar, PhD, associate professor at The Jackson Laboratory for Genomic Medicine, discovered that this chain reaction of stem cell changes caused a boost in the production of monocytes. The authors found that, due to the innate cellular changes from a severe case of COVID, patients in recovery ended up producing a larger amount of inflammatory cytokines, rather than monocytes – distinct from samples collected from healthy patients and those recovering from other critical illnesses.

These changes to patients’ epigenetic landscapes were observed even a year after the initial COVID-19 infection. While the small participant pool meant that the research team could not establish a direct line between these innate changes and any ensuing health outcomes, the research provides us with clues as to why patients continue to struggle with inflammation and long COVID symptoms well after they recover.

While the authors reiterate the study’s limitations and hesitate to make any clear-cut associations between the results and long-term health outcomes, Wolfgang Leitner, PhD, from the NIH’s National Institute of Allergy and Infectious Diseases, predicts that long COVID can, at least in part, be explained by the changes in innate immune responses.

“Ideally, the authors would have had cells from each patient before they got infected, as a comparator, to see what the epigenetic landscape was before COVID changed it,” said Dr. Leitner. “Clear links between the severity of COVID and genetics were discovered already early in the pandemic and this paper should prompt follow-up studies that link mutations in immune genes with the epigenetic changes described here.”

Dr. Leitner said he had some initial predictions about the long-term impact of COVID-19, but he had not anticipated some of what the study’s findings now show.

“Unlike in the case of, for example, influenza, where the lungs go into ‘repair mode’ after the infection has been resolved – which leaves people susceptible to secondary infections for up to several months – this study shows that after severe COVID, the immune system remains in ‘emergency mode’ and in a heightened state of inflammation,” said Dr. Leitner.

“That further aggravates the problem the initial strong inflammation causes: even higher risk of autoimmune disease, but also, cancer.”

Commenting on the findings, Eric Topol, MD, editor-in-chief of Medscape Medical News, said the study presents “evidence that a key line of immune cells are essentially irrevocably, epigenetically altered and activated.

“You do not want to have this [COVID],” he added.

The study also highlights the researchers’ novel approach to isolating hematopoietic stem cells, found largely in bone marrow. This type of research has been limited in the past because of how costly and invasive it can be to analyze cells in bone marrow. But, by isolating and enriching hematopoietic stem cells, the team can decipher the full cellular diversity of the cells’ bone marrow counterparts.

“This revelation opened the doors to study, at single-cell resolution, how stem cells are affected upon infection and vaccination with a simple blood draw,” representatives from the Jackson lab said in a press release.

By the end of August 2022, overall use of mental health services was almost 40% higher than before the COVID-19 pandemic, while spending increased by 54%, according to a new study by researchers at the RAND Corporation.

During the early phase of the pandemic, from mid-March to mid-December 2020, before the vaccine was available, in-person visits decreased by 40%, while telehealth visits increased by 1,000%, reported Jonathan H. Cantor, PhD, and colleagues at RAND, and at Castlight Health, a benefit coordination provider, in a paper published online in JAMA Health Forum.

Between December 2020 and August 2022, telehealth visits stayed stable, but in-person visits creeped back up, eventually reaching 80% of prepandemic levels. However, “total utilization was higher than before the pandemic,” Dr. Cantor, a policy researcher at RAND, told this news organization. 

“It could be that it’s easier for individuals to receive care via telehealth, but it could also just be that there’s a greater demand or need since the pandemic,” said Dr. Cantor. “We’ll just need more research to actually unpack what’s going on,” he said.

Initial per capita spending increased by about a third and was up overall by more than half. But it’s not clear how much of that is due to utilization or to price of services, said Dr. Cantor. Spending for telehealth services remained stable in the post-vaccine period, while spending on in-person visits returned to prepandemic levels.

Dr. Cantor and his colleagues were not able to determine whether utilization was by new or existing patients, but he said that would be good data to have. “It would be really important to know whether or not folks are initiating care because telehealth is making it easier,” he said.

The authors analyzed about 1.5 million claims for anxiety disorders, major depressive disorder, bipolar disorder, schizophrenia, and posttraumatic stress disorder, out of claims submitted by 7 million commercially insured adults whose self-insured employers used the Castlight benefit.

Dr. Cantor noted that this is just a small subset of the U.S. population. He said he’d like to have data from Medicare and Medicaid to fully assess the impact of the COVID-19 pandemic on mental health and of telehealth visits.

“This is a still-burgeoning field,” he said about telehealth. “We’re still trying to get a handle on how things are operating, given that there’s been so much change so rapidly.”

Meanwhile, 152 major employers responding to a large national survey this summer said that they’ve been grappling with how COVID-19 has affected workers. The employers include 72 Fortune 100 companies and provide health coverage for more than 60 million workers, retirees, and their families.

Seventy-seven percent said they are currently seeing an increase in depression, anxiety, and substance use disorders as a result of the pandemic, according to the Business Group on Health’s survey. That’s up from 44% in 2022.

Going forward, employers will focus on increasing access to mental health services, the survey reported.

“Our survey found that in 2024 and for the near future, employers will be acutely focused on addressing employees’ mental health needs while ensuring access and lowering cost barriers,” Ellen Kelsay, president and CEO of Business Group on Health, said in a statement.

The study was supported by grants from the National Institute of Mental Health and the National Institute on Aging. Coauthor Dena Bravata, MD, a Castlight employee, reported receiving personal fees from Castlight Health during the conduct of the study. Coauthor Christopher M. Whaley, a RAND employee, reported receiving personal fees from Castlight Health outside the submitted work.

Between December 2020 and August 2022, telehealth visits stayed stable, but in-person visits creeped back up, eventually reaching 80% of prepandemic levels. However, “total utilization was higher than before the pandemic,” Dr. Cantor, a policy researcher at RAND, told this news organization. 

“It could be that it’s easier for individuals to receive care via telehealth, but it could also just be that there’s a greater demand or need since the pandemic,” said Dr. Cantor. “We’ll just need more research to actually unpack what’s going on,” he said.

Initial per capita spending increased by about a third and was up overall by more than half. But it’s not clear how much of that is due to utilization or to price of services, said Dr. Cantor. Spending for telehealth services remained stable in the post-vaccine period, while spending on in-person visits returned to prepandemic levels.

Dr. Cantor and his colleagues were not able to determine whether utilization was by new or existing patients, but he said that would be good data to have. “It would be really important to know whether or not folks are initiating care because telehealth is making it easier,” he said.

The authors analyzed about 1.5 million claims for anxiety disorders, major depressive disorder, bipolar disorder, schizophrenia, and posttraumatic stress disorder, out of claims submitted by 7 million commercially insured adults whose self-insured employers used the Castlight benefit.

Dr. Cantor noted that this is just a small subset of the U.S. population. He said he’d like to have data from Medicare and Medicaid to fully assess the impact of the COVID-19 pandemic on mental health and of telehealth visits.

“This is a still-burgeoning field,” he said about telehealth. “We’re still trying to get a handle on how things are operating, given that there’s been so much change so rapidly.”

Meanwhile, 152 major employers responding to a large national survey this summer said that they’ve been grappling with how COVID-19 has affected workers. The employers include 72 Fortune 100 companies and provide health coverage for more than 60 million workers, retirees, and their families.

Seventy-seven percent said they are currently seeing an increase in depression, anxiety, and substance use disorders as a result of the pandemic, according to the Business Group on Health’s survey. That’s up from 44% in 2022.

Going forward, employers will focus on increasing access to mental health services, the survey reported.

“Our survey found that in 2024 and for the near future, employers will be acutely focused on addressing employees’ mental health needs while ensuring access and lowering cost barriers,” Ellen Kelsay, president and CEO of Business Group on Health, said in a statement.

The study was supported by grants from the National Institute of Mental Health and the National Institute on Aging. Coauthor Dena Bravata, MD, a Castlight employee, reported receiving personal fees from Castlight Health during the conduct of the study. Coauthor Christopher M. Whaley, a RAND employee, reported receiving personal fees from Castlight Health outside the submitted work.

It’s been estimated that up to one-third of people who survive acute SARS-CoV-2 infection will suffer a post-viral syndrome with lingering neurologic and other symptoms – now known as long COVID or neurological postacute sequelae of SARS-CoV-2 infection (Neuro-PASC).

However, new research suggests that may be an underestimate and that far more people may be suffering from long COVID without ever having tested positive for the virus. Researchers found a significant proportion of patients in their small study who had never tested positive for COVID-19 but who were having symptoms of long COVID nevertheless showed evidence of immune responses consistent with previous exposure.

“We estimate that millions of people got COVID in the U.S. during the first year of the pandemic and then developed long COVID, yet they did not get a positive COVID diagnosis because of testing limitations,” Igor J. Koralnik, MD, of Northwestern Medicine Comprehensive COVID-19 Center in Chicago, said in an interview.

He noted that many post-COVID-19 clinics in the United States don’t accept people with long COVID symptoms who do not have a positive test result.

Patients with long COVID symptoms but without laboratory evidence of prior infection, “who have often been rejected and stigmatized, should feel vindicated by the results of our study,” Dr. Koralnik said.

“We think that those patients deserve the same clinical care as those with a positive test, as well as inclusion in research studies. This is what we are doing at Northwestern Medicine’s Comprehensive COVID[-19] Center,” Dr. Koralnik added.

The study was published online in the journal Neurology: Neuroimmunology & Neuroinflammation.

Delayed care

The researchers measured SARS-CoV-2-specific humoral and cell-mediated immune responses against nucleocapsid protein and spike proteins, which indicate a prior COVID-19 infection, in 29 patients with post-viral syndrome after suspected COVID-19, including neurologic symptoms such as cognitive impairment, headache, and fatigue, but who did not have a confirmed positive COVID-19 test.

They did the same in 32 age- and sex-matched COVID long haulers with confirmed Neuro-PASC and 18 healthy controls with none of the symptoms of long COVID and no known exposure to SARS-CoV-2 or positive test result.

They found that 12 of the 29 patients (41%) with post-viral syndrome (but no positive COVID-19 test) had detectable humoral and cellular immune responses consistent with prior exposure to SARS-CoV-2. Three-quarters harbored antinucleocapsid and 50% harbored antispike responses.

“Our data suggest that at least 4 million people with post-viral syndrome similar to long COVID may indeed have detectable immune responses to support a COVID diagnosis,” Dr. Koralnik said in a news release.

The 12 patients with post-viral syndrome but without a confirmed COVID-19 test had neurologic symptoms similar to those of patients with confirmed Neuro-PASC.

However, lack of a confirmed COVID-19 diagnosis likely contributed to the 5-month delay in the median time from symptom onset to clinic visit, the researchers said. They were evaluated at a median of 10.7 months vs. 5.4 months for Neuro-PASC patients.

Dr. Koralnik said in an interview that the “most important take-home message” of the study is that patients with post-viral syndrome often present with clinical manifestations similar to those of confirmed patients with Neuro-PASC, suggesting that a positive result by commercially available SARS-CoV-2 diagnostic test should not be a prerequisite for accessing care.

Patients with post-viral syndrome may benefit from the same clinical care as confirmed patients with Neuro-PASC, and the absence of a positive SARS-CoV-2 test should not preclude or delay treatment, he added.

A new strain of COVID-19 that was identified only a week ago in the United States has prompted the Centers for Disease Control and Prevention to take the rare step of issuing a formal message that it could evade vaccines or the protection of natural immunity. 

The strain is called BA.2.86 and is of particular concern because of its more than 30 mutations, which means it may behave very differently than previous versions of the virus. That number of mutations is on par with the difference between variants so serious that they were formally named, such as between Delta and Omicron, the CDC explained in the risk assessment issued Aug. 23.

Worldwide, health agencies are issuing a flurry of updates on BA.2.86. The strain only recently landed on the World Health Organization’s radar when it was named a “variant under monitoring” on Aug. 17. The CDC announced the same day that it had been detected in the United States.

Among the characteristics the CDC monitors for are how contagious a strain is, how well it responds to treatment, and how severely it affects people.

“BA.2.86 may be more capable of causing infection in people who have previously had COVID-19 or who have received COVID-19 vaccines,” the CDC risk assessment stated.

The agency is evaluating how well the forthcoming updated vaccine, due out in September, performs against BA.2.86.

A new forecast also released this week by the CDC predicts hospitalizations due to the virus will continue their upward trend through at least mid-September. Currently, about 1,800 people are hospitalized daily with COVID-19. The new prediction shows that number has a small potential to drop as low as 1,100 daily, but it could also increase by as many as 7,500 per day. The most likely scenario lands somewhere in the middle of that range, with daily hospital admissions of between 2,000 and 4,000 people by Sept. 18.

The CDC said there is “no evidence” that BA.2.86 is causing more severe illness but said that could change as more information becomes available. Health experts typically gauge severity by the rate of COVID hospitalizations.

The journal Nature reported that many scientists see similarities between the emergence of BA.2.86 and that of Omicron, which rapidly spread around the world in late 2021.

“There’s a little bit of déjà vu all over again,” University of Michigan virologist Adam Lauring, MD, PhD, whose lab detected one of the first U.S. cases of BA.2.86, told Nature.

Dr. Lauring, as well as the CDC and the WHO, all caution that more data is needed to truly understand the threat posed by BA.2.86.

“There’s good reason to think it won’t be like the Omicron wave, but it’s early days,” Dr. Lauring said.

People may get more protection against COVID-19 if they get their vaccinations and boosters in the same arm, a new study says.

Scientists in Germany looked at health data for 303 people who got the mRNA vaccine and then a booster shot. Their antibody levels were measured two weeks after the second shot. None of the people had had COVID before the vaccinations.

Scientists found that the number of protective “killer T cells” was higher in the 147 study participants who got both shots in the same arm, said the study published in EBioMedicine.

The killer cells were found in 67% of cases in which both shots went into the same arm, compared with 43% of cases with different arms.

“That may suggest that that ipsilateral vaccination (in the same arm) is more likely to provide better protection should the vaccinated person become infected with the SARS-CoV-2 virus,” Laura Ziegler, a doctoral student at Saarland University, Germany, said in a news release.

William Schaffner, MD, a professor in the Division of Infectious Diseases at Vanderbilt University Medical Center, Nashville, Tenn., told CBS News that same-arm vaccinations may work better because the cells that provide the immune response are in local lymph nodes.

There’s greater immunological response if the immune cells in the lymph nodes are restimulated in the same place, said Dr. Schaffner, who was not involved in the German study.

The scientists from Saarland University said more research is needed before they can be certain that having vaccinations in the same arm is actually more effective for COVID shots and sequential vaccinations against diseases such as the flu.

By now, concerns about COVID-related lawsuits have faded into the rear view mirror for most physicians.

But just when COVID lawsuits appear to be dwindling out, legal experts see a new lawsuit risk on the horizon – long COVID claims. While some say it’s doubtful the claims will succeed, the lawsuits could still create legal headaches for doctors in the form of time and money.

Long COVID claims are defined as complaints that allege that a diagnosis of long COVID was missed or delayed and that caused harm or injury. Lawsuits may also include claims in which patients allege that they were misdiagnosed as having long COVID when they were really suffering from another condition.

So far, a handful of long COVID claims have come down the pipeline, said Peter A. Kolbert, JD, senior vice president of claims and litigation services for Healthcare Risk Advisors, part of TDC Group.

“This is an area that is emerging as we speak,” Mr. Kolbert said. “We are starting to see these claims trickle in.”

In a recent case, for example, a patient sued her primary care physician for negligence, alleging her original SARS-CoV-2 infection was mismanaged and that this led to permanent neuropathy from long COVID. Had the patient been treated appropriately, the patient contends, she would not have developed long COVID or the resulting neuropathy, said Mr. Kolbert. An outcome in the case has not yet been reached, added Mr. Kolbert, who heard about the claim from a colleague.

The increase in the number of lawsuits raises concerns about how courts and juries might decide long COVID claims when so much about the condition is still unknown and best treatment practices are still developing. Research shows that long COVID occurs in at least 10% of cases of SARS-CoV-2 infection, and more than 200 symptoms have been identified. A Kaiser Family Foundation study found that 15% of the U.S. population believe they have experienced the symptoms of long COVID at some point, and 6% of people believe they currently have long COVID.

The risk of long COVID lawsuits underscores the importance of physicians taking proactive steps to protect themselves from liability when treating patients who might have the condition, say legal experts.

“There are legal standards that say new, unestablished scientific principles shouldn’t be first tested by a jury, they should be recognized and established within their [professional] area,” Mr. Kolbert said. “While we are seeing lawsuits related to long COVID, I think it is truly putting the cart before the horse, because there needs to be societal recognition that we’re still learning how to define and treat long COVID.”
 

What are patients alleging?

In the few long COVID claims that have arisen, some complaints have alleged delay in the recognition and treatment of long COVID, according to Mr. Kolbert. There have also been claims that physicians failed to refer a patient with long COVID to a specialist in a timely way and that this results in the patient’s experiencing chronic fatigue or a neuropathy.

Fatigue is one of the most common symptoms associated with long COVID, according to recent studies. Other symptoms include postexertional malaise, brain fog, and gastrointestinal problems.

Another rising legal theme is failure to adequately communicate with patients about what long COVID is and what it entails.

Whether plaintiffs who bring long COVID claims will be successful in court remains a question.

Andrew D. DeSimone, JD, a Lexington, Ky.–based medical malpractice defense attorney, said he has not seen any claims involving long COVID. He added that a long COVID claim would be challenging to prove, considering the standard of care for treating the condition is still evolving. Plaintiffs in a medical malpractice action must prove that physicians owed a duty of care to the patient, that the doctor breached that duty by failing to conform to the standard of care, and that the breach caused an injury that harmed the patient.

Mr. DeSimone also doubts whether juries would be very sympathetic to such plaintiffs.

“There’s a lot of fatigue around COVID still,” he said. “I don’t know if a jury would buy into someone claiming long COVID. I think the claim would have a hard time gaining traction. Not that it’s impossible.”

Another unanswered question is whether legal protections enacted by states during the pandemic might apply to long COVID claims.

Shortly after the pandemic started, most states enacted laws or executive orders that shielded physicians from liability claims relating to the prevention and treatment of COVID-19, unless gross negligence or willful misconduct is proved. The U.S. Department of Health and Human Services published a declaration under the Public Readiness and Emergency Preparedness Act (PREP Act) that provided liability immunity to health care professionals for any activity related to medical countermeasures against COVID-19.

Some of these state immunities have since expired. Other states have extended their legal protections for short periods. In Indiana, for example, physicians and businesses are protected until Dec. 31, 2024, from civil tort actions that allege damages arising from COVID-19.

It’s possible that in long COVID lawsuits, physicians would be protected by the immunities unless the cases come after the protections expire, said J. Richard Moore, a medical liability defense attorney based in Indianapolis.

“I could foresee long COVID claims that don’t accrue until after December 2024, meaning it only becomes clear that a patient is struggling with long COVID–related symptoms after that date,” he said. “That could result in COVID claims that do not fall under the immunities.”

Mr. Moore said that if long COVID claims become truly problematic, the legislature could extend the immunities.

Other states, such as Washington, have statutes in place that increase the burden of proof for plaintiffs in cases in which care is affected by COVID and/or the treating of COVID. Elizabeth A. Leedom, a Seattle-based medical liability defense attorney, said the law would likely encompass long COVID claims if the care and treatment at issue occurred during the COVID state of emergency.

Compliance with current treatment guidelines is likely to be a good defense against any claim of delay/failure to diagnose COVID, including long COVID, she said.

Mr. Kolbert, however, doubts that the state immunities would protect against the claims.

“Courts are enforcing qualified immunities as to [traditional] COVID claims. However, I suspect that long COVID claims will fall into a category of traditional medical malpractice claim, such as delay in or failure to diagnose,” he said. In such cases, physicians “may not be able to take advantage of state-qualified immunities. Of course, this will depend upon the language of each state’s qualified immunity provisions.”

As for the statute of limitations, the clock generally starts running either when the alleged negligent conduct occurred or when the patient knew or, in the exercise of ordinary diligence, should have known, that they had been harmed by the alleged negligence, Mr. Moore said. Statutes of limitations are state specific, but the majority of states mandate a 2- to 3-year limit between the injury and the filing of a claim.

So, while the statute of limitations may be soon expiring for alleged harm that occurred during the pandemic, for patients newly diagnosed with long COVID or who have just discovered associated injuries, the clock may have just started ticking.
 

How to protect yourself against suits

Avoiding liability associated with long COVID involves the traditional legal guidance physicians are used to hearing, but with an added factor, Mr. Kolbert said.

There always needs to be communication with patients regarding the disease process, but in this area, there needs to be strong communication as to whether patients have had COVID in the past and what symptoms they are experiencing, he said. Physicians should ensure that patients know that long COVID may present in a variety of ways and that there is no definitive test for long COVID.

Physicians should document when the patient has been instructed to follow up and should take necessary steps to ensure the patient returns for follow-up care, he added.

On the opposite side of the spectrum is making sure not to assume a condition or symptom is the result of long COVID, he said. Care should be taken not to diagnose long COVID without excluding traditional causes.

“Ensure that patients know that COVID is not over, per se, and that science supports vaccination,” Mr. Kolbert said. “The best defense here is a strong communicative offense, engaging with the patient and thoughtfully charting about this.”

By now, concerns about COVID-related lawsuits have faded into the rear view mirror for most physicians.

But just when COVID lawsuits appear to be dwindling out, legal experts see a new lawsuit risk on the horizon – long COVID claims. While some say it’s doubtful the claims will succeed, the lawsuits could still create legal headaches for doctors in the form of time and money.

Long COVID claims are defined as complaints that allege that a diagnosis of long COVID was missed or delayed and that caused harm or injury. Lawsuits may also include claims in which patients allege that they were misdiagnosed as having long COVID when they were really suffering from another condition.

So far, a handful of long COVID claims have come down the pipeline, said Peter A. Kolbert, JD, senior vice president of claims and litigation services for Healthcare Risk Advisors, part of TDC Group.

“This is an area that is emerging as we speak,” Mr. Kolbert said. “We are starting to see these claims trickle in.”

In a recent case, for example, a patient sued her primary care physician for negligence, alleging her original SARS-CoV-2 infection was mismanaged and that this led to permanent neuropathy from long COVID. Had the patient been treated appropriately, the patient contends, she would not have developed long COVID or the resulting neuropathy, said Mr. Kolbert. An outcome in the case has not yet been reached, added Mr. Kolbert, who heard about the claim from a colleague.

The increase in the number of lawsuits raises concerns about how courts and juries might decide long COVID claims when so much about the condition is still unknown and best treatment practices are still developing. Research shows that long COVID occurs in at least 10% of cases of SARS-CoV-2 infection, and more than 200 symptoms have been identified. A Kaiser Family Foundation study found that 15% of the U.S. population believe they have experienced the symptoms of long COVID at some point, and 6% of people believe they currently have long COVID.

The risk of long COVID lawsuits underscores the importance of physicians taking proactive steps to protect themselves from liability when treating patients who might have the condition, say legal experts.

“There are legal standards that say new, unestablished scientific principles shouldn’t be first tested by a jury, they should be recognized and established within their [professional] area,” Mr. Kolbert said. “While we are seeing lawsuits related to long COVID, I think it is truly putting the cart before the horse, because there needs to be societal recognition that we’re still learning how to define and treat long COVID.”
 

What are patients alleging?

In the few long COVID claims that have arisen, some complaints have alleged delay in the recognition and treatment of long COVID, according to Mr. Kolbert. There have also been claims that physicians failed to refer a patient with long COVID to a specialist in a timely way and that this results in the patient’s experiencing chronic fatigue or a neuropathy.

Fatigue is one of the most common symptoms associated with long COVID, according to recent studies. Other symptoms include postexertional malaise, brain fog, and gastrointestinal problems.

Another rising legal theme is failure to adequately communicate with patients about what long COVID is and what it entails.

Whether plaintiffs who bring long COVID claims will be successful in court remains a question.

Andrew D. DeSimone, JD, a Lexington, Ky.–based medical malpractice defense attorney, said he has not seen any claims involving long COVID. He added that a long COVID claim would be challenging to prove, considering the standard of care for treating the condition is still evolving. Plaintiffs in a medical malpractice action must prove that physicians owed a duty of care to the patient, that the doctor breached that duty by failing to conform to the standard of care, and that the breach caused an injury that harmed the patient.

Mr. DeSimone also doubts whether juries would be very sympathetic to such plaintiffs.

“There’s a lot of fatigue around COVID still,” he said. “I don’t know if a jury would buy into someone claiming long COVID. I think the claim would have a hard time gaining traction. Not that it’s impossible.”

Another unanswered question is whether legal protections enacted by states during the pandemic might apply to long COVID claims.

Shortly after the pandemic started, most states enacted laws or executive orders that shielded physicians from liability claims relating to the prevention and treatment of COVID-19, unless gross negligence or willful misconduct is proved. The U.S. Department of Health and Human Services published a declaration under the Public Readiness and Emergency Preparedness Act (PREP Act) that provided liability immunity to health care professionals for any activity related to medical countermeasures against COVID-19.

Some of these state immunities have since expired. Other states have extended their legal protections for short periods. In Indiana, for example, physicians and businesses are protected until Dec. 31, 2024, from civil tort actions that allege damages arising from COVID-19.

It’s possible that in long COVID lawsuits, physicians would be protected by the immunities unless the cases come after the protections expire, said J. Richard Moore, a medical liability defense attorney based in Indianapolis.

“I could foresee long COVID claims that don’t accrue until after December 2024, meaning it only becomes clear that a patient is struggling with long COVID–related symptoms after that date,” he said. “That could result in COVID claims that do not fall under the immunities.”

Mr. Moore said that if long COVID claims become truly problematic, the legislature could extend the immunities.

Other states, such as Washington, have statutes in place that increase the burden of proof for plaintiffs in cases in which care is affected by COVID and/or the treating of COVID. Elizabeth A. Leedom, a Seattle-based medical liability defense attorney, said the law would likely encompass long COVID claims if the care and treatment at issue occurred during the COVID state of emergency.

Compliance with current treatment guidelines is likely to be a good defense against any claim of delay/failure to diagnose COVID, including long COVID, she said.

Mr. Kolbert, however, doubts that the state immunities would protect against the claims.

“Courts are enforcing qualified immunities as to [traditional] COVID claims. However, I suspect that long COVID claims will fall into a category of traditional medical malpractice claim, such as delay in or failure to diagnose,” he said. In such cases, physicians “may not be able to take advantage of state-qualified immunities. Of course, this will depend upon the language of each state’s qualified immunity provisions.”

As for the statute of limitations, the clock generally starts running either when the alleged negligent conduct occurred or when the patient knew or, in the exercise of ordinary diligence, should have known, that they had been harmed by the alleged negligence, Mr. Moore said. Statutes of limitations are state specific, but the majority of states mandate a 2- to 3-year limit between the injury and the filing of a claim.

So, while the statute of limitations may be soon expiring for alleged harm that occurred during the pandemic, for patients newly diagnosed with long COVID or who have just discovered associated injuries, the clock may have just started ticking.

The Centers for Disease Control and Prevention is tracking a newly discovered strain of COVID-19 called BA.2.86.

On Aug. 17, the agency posted on X, formerly known as Twitter, that the lineage has been detected in the United States, Denmark, and Israel. 

“As we learn more about BA.2.86, CDC’s advice on protecting yourself from COVID-19 remains the same,” the CDC said on X. 

A case of BA.2.86 was detected at a laboratory at the University of Michigan, CBS News reported. It’s not clear how the university obtained the sample that was sequenced. A case was also detected in the United Kingdom, the news outlet said. 

The World Health Organization is also tracking BA.2.86 and has classified it as a “variant under monitoring.” 

“More data are needed to understand this COVID-19 variant and the extent of its spread, but the number of mutations warrants attention. WHO will update countries and the public as we learn more,” the WHO said on X.

The strain is so new that scientists don’t know if BA.2.86 is more easily spread, causes more severe symptoms than existing strains, or will be more resistant to vaccines and natural immunity developed over the last few years. 

Early research indicates BA.2.86 “will have equal or greater escape than XBB.1.5 from antibodies elicited by pre-Omicron and first-generation Omicron variants,” Jesse Bloom, PhD, a virologist at the Fred Hutchinson Cancer Center, said in a slide deck published Aug. 17. (XBB.1.5 is the Omicron subvariant that is targeted in the updated COVID booster shot to be released soon.)

Still, Dr. Bloom noted that “even if a highly mutated new variant like BA.2.86 starts to spread, we will be in a far better place than we were in 2020 and 2021, since most people have some immunity to SARS-CoV-2 now.”
