Delaying flu vaccine didn’t drop fever rate for childhood immunizations
according to a randomized trial.
An increased risk for febrile seizures had been seen when the three vaccines were administered together, wrote Emmanuel B. Walter, MD, MPH, and coauthors, so they constructed a trial that compared a simultaneous administration strategy that delayed inactivated influenza vaccine (IIV) administration by about 2 weeks.
In all, 221 children aged 12-16 months were enrolled in the randomized study. A total of 110 children received quadrivalent IIV (IIV4), DTaP, and 13-valent pneumococcal conjugate vaccine (PCV13) simultaneously and returned for a dental health education visit 2 weeks later. For 111 children, DTaP and PCV13 were administered at study visit 1, and IIV4 was given along with dental health education 2 weeks later. Most children in both groups also received at least one nonstudy vaccine at the first study visit. Eleven children in the simultaneous group and four in the sequential group didn’t complete the study.
There was no difference between study groups in the combined rates of fever on the first 2 days after study visits 1 and 2 taken together: 8% of children in the simultaneous group and 9% of those in the sequential group had fever of 38° C or higher (adjusted relative risk, 0.87; 95% confidence interval, 0.36-2.10).
However, children in the simultaneous group were more likely to receive antipyretic medication in the first 2 days after visit 1 (37% versus 22%; P = .020), reported Dr. Walter, professor of pediatrics at Duke University, Durham, N.C., and coauthors. Because it’s rare for febrile seizures to occur after immunization, the authors didn’t make the occurrence of febrile seizure a primary or secondary endpoint of the study; no seizures occurred in study participants. They did hypothesize that the total proportion of children having fever would be higher in the simultaneous than in the sequential group – a hypothesis not supported by the study findings.
Children were excluded, or their study vaccinations were delayed, if they had received antipyretic medication within the 72 hours preceding the visit or at the study visit, or if they had a temperature of 38° C or more.
Parents monitored participants’ temperatures for 8 days after visits by using a study-provided temporal thermometer once daily at about the same time, and also by checking the temperature if their child felt feverish. Parents also recorded any antipyretic use, medical care, other symptoms, and febrile seizures.
The study was stopped earlier than anticipated because unexpectedly high levels of influenza activity made it unethical to delay influenza immunization, explained Dr. Walter and coauthors.
Participants were a median 15 months old; most were non-Hispanic white and had private insurance. Most participants didn’t attend day care.
“Nearly all fever episodes and days of fever on days 1-2 after the study visits occurred after visit 1,” reported Dr. Walter and coinvestigators. They saw no difference between groups in the proportion of children who had a fever of 38.6° C on days 1-2 after either study visit.
The mean peak temperature – about 38.5° C – on combined study visits 1 and 2 didn’t differ between groups. Similarly, for those participants who had a fever, the mean postvisit fever duration of 1.3 days was identical between groups.
Parents also were asked about their perceptions of the vaccination schedule their children received. Over half of parents overall (56%) reported that they disliked having to bring their child in for two separate clinic visits, with more parents in the sequential group than the simultaneous group reporting this (65% versus 48%).
Generalizability of the findings and comparison with previous studies are limited, noted Dr. Walter and coinvestigators, because the composition of influenza vaccine varies from year to year. No signal for seizures was seen in the Vaccine Safety Datalink after IIV during the 2017-2018 influenza season, wrote the investigators. The 2010-2011 influenza season’s IIV formulation was associated with increased febrile seizure risk, indicating that the IIV formulation for that year may have been more pyrogenic than the 2017-2018 formulation.
Also, children deemed at higher risk of febrile seizure were excluded from the study, so findings may have limited applicability to these children. The lack of parental blinding also may have influenced antipyretic administration or other symptom reporting, although objective temperature measurement should not have been affected by the lack of blinding, wrote Dr. Walker and collaborators.
The study was funded by the Centers for Disease Control and Prevention. One coauthor reported potential conflicts of interest from financial support received from GlaxoSmithKline, Sanofi Pasteur, Pfizer, Merck, Protein Science, Dynavax, and Medimmune. The remaining authors have no relevant financial disclosures.

CDC begins coronavirus diagnostic test kit distribution; new case confirmed in Wisconsin
The Centers for Disease Control and Prevention and the Wisconsin Department of Health Services confirmed a new case of the 2019 Novel Coronavirus (2019-nCoV) on Feb. 5, 2020, bringing the total number of cases in the United States to 12.*
Earlier in the day, Nancy Messonnier, MD, director of the CDC National Center for Immunization and Respiratory Diseases, told reporters that 206 individuals under investigation had tested negative for infection with the novel virus and that tests were pending on another 76 individuals.
The agency also announced during a press briefing call that diagnostic test kits will begin shipping on Feb. 5, less than 24 hours after receiving an emergency use authorization from the Food and Drug Administration. Full information is available in an article published in the Morbidity and Mortality Weekly Report.
The emergency use authorization will allow for broader use of the CDC’s 2019-nCoV Real Time RT-PCR Diagnostic Panel, which to date has been limited for use at CDC laboratories. Under the emergency use authorization, the diagnostic kit is authorized for patients who meed the CDC criteria for 2019-nCoV testing. The diagnostic test is a reverse transcriptase polymerase chain reaction test that provides presumptive detection of 2019-nCoV from respiratory secretions, such as nasal or oral swabs. A positive test indicates likely infection, although a negative test does not preclude infection and should not be the sole determination for patient management decisions.
“Today, the test kits will start shipping to over 100 U.S. public health labs,” she said. “Each of these labs is required to perform international verification for [Clinical Laboratory Improvement Amendments] compliance prior to reporting out. This process is expected to take a few days.”
Dr. Messonnier said that 200 test kits will be distributed to domestic labs and another 200 test kits will go to select international labs. Each kit can perform diagnostics on 700-800 patient samples.
“What that means is that, by the start of next week, we expect there to be much enhanced capacity for laboratory testing closer to our patients,” she said, adding that additional test kits are being produced and will be available for ordering in the future. Each laboratory that places an order will receive one test kit.
“Distribution of these tests will improve the global capacity to detect and respond to this new virus,” Dr. Messonnier said. “Availability of this test is a starting place for greater commercial availability of diagnostic testing for nCoV.”
The CDC also said that the next batch of passengers arriving from Wuhan, China, will be arriving in one of four locations: Travis Air Force Base, Fairfield, Calif.; Marine Corps Air Station Miramar, San Diego; Lackland Air Force Base, San Antonio; and Eppley Airfield, Omaha, Neb. Passengers will be quarantined for up to 14 days from the day the flight left Wuhan and medical care will be provided if needed.
“We do not believe these people pose a threat to the communities where they are being housed as we are taking measures to minimize any contact,” she said, adding that confirmed infections are expected among these and other returning travelers.
Dr. Messonnier warned that the quarantine measures “may not catch every single returning traveler returning with novel coronavirus, given the nature of this virus and how it is spreading. But if we can catch the majority of them, that will slow the entry of this virus into the United States.”

The 2019 novel coronavirus: Case review IDs clinical characteristics
A group of physicians in Wuhan, China, who are treating patients with the 2019 novel coronavirus have gone the extra mile to share their clinical experiences with colleagues around the world.
Nanshan Chen, MD, of Jinyintan Hospital, Wuhan, and his team conducted a retrospective study on 99 cases and, in very short order, published their initial findings in the Lancet online on Jan. 29. These findings could guide action in other cases and help clinicians all over the world create treatment plans for patients of the 2019-nCoV.
The findings show that and characteristics of those with fatal infections align with the MuLBSTA score – an early warning model for predicting viral pneumonia–related mortality, according to a case review.
Of 99 patients who presented with 2019-nCoV pneumonia at Jinyintan Hospital between Jan. 1 and Jan. 20, 67 were men, the mean age was 55.5 years, and 50 patients had chronic diseases.
“All the data of included cases have been shared with [the World Health Organization]. The study was approved by Jinyintan Hospital Ethics Committee and written informed consent was obtained from patients involved before enrollment when data were collected retrospectively,” the researchers noted.
Nearly half of the patients (49%) lived or worked near a specific seafood market, suggesting disease clustering.
Clinical manifestations affecting the majority of patients included fever and cough in 83% and 82% of patients, respectively. Other symptoms included shortness of breath in 31%, muscle aches in 11%, confusion in 9%, headache in 8%, sore throat in 5%, and rhinorrhea, chest pain, diarrhea, and nausea and vomiting in 1%-4% of patients, the investigators found.
Imaging showed bilateral pneumonia in 75% of cases, multiple mottling and ground-glass opacity in 14%, and pneumothorax in 1%. Organ function damage was present in a third of patients at admission: 17% had acute respiratory distress syndrome (ARDS) – including 11 patients who worsened quickly and died of multiple organ failure. Eight percent had acute respiratory injury, 3% had acute renal injury, 4% had septic shock, and 1% had ventilator-associated pneumonia, they said, noting that all cases were confirmed by real-time polymerase chain reaction.
A notable laboratory finding was reduced absolute lymphocyte counts in most patients, the investigators said.
All patients were treated in isolation and 76% received antiviral treatment with oseltamivir, ganciclovir, lopinavir, or ritonavir for 3-14 days (median, 3 days). Most patients also received antibiotic treatment, including a single antibiotic in 25% of cases and combination therapy in 45%, with most antibiotics used to cover “common pathogens and some atypical pathogens,” they said, adding that “when secondary bacterial infection occurred, medication was administered according to the results of bacterial culture and drug sensitivity.”
Cephalosporins, quinolones, carbapenems, tigecycline against methicillin-resistant Staphylococcus aureus, linezolid, and antifungal drugs were used, and duration ranged from 3 to 17 days (median, 5 days).
Nineteen patients also received steroid treatments.
As of Jan. 25, 31 patients had been discharged and 57 remained hospitalized. Of the 11 who died, the first 2 were a 61-year-old man and a 69-year-old man, each diagnosed with severe pneumonia and ARDS. The first experienced sudden cardiac arrest and died on admission day 11, and the second died of severe pneumonia, septic shock, and respiratory failure on admission day 9. Neither had underlying disease, but both had a long history of smoking, the investigators noted.
“The deaths of these two patients were consistent with the MuLBSTA score,” they wrote, explaining that the scoring system takes into account multilobular infiltration, lymphopenia, bacterial coinfection, smoking history, hypertension, and age.
Eight of the nine other patients who died had lymphopenia, seven had bilateral pneumonia, five were over age 60 years, three had hypertension, and one was a heavy smoker, they added.
Most coronavirus infections cause mild symptoms and have good prognosis, but some patients with the 2019-nCoV, which was identified Jan. 7 following the development of several cases of pneumonia of unknown etiology in Wuhan, develop fatal disease. The paucity of data regarding epidemiology and clinical features of pneumonia associated with 2019-nCoV prompted the current retrospective study at the center where the first cases were admitted, the investigators explained.
They noted that the sequence of 2019-nCoV “is relatively different from the six other coronavirus subtypes, including the highly pathogenic severe acute respiratory syndrome (SARS)-CoV and Middle East Respiratory Syndrome (MERS)-CoV, as well as the human coronaviruses (HCoV)-OC43, -229E, -NL63, and -HKU1 that induce mild upper respiratory disease, but can be classified as a betacoronavirus with evidence of human-to-human transmission.
Mortality associated with SARS-CoV and MERS-CoV have been reported as more than 10% and more than 35%, respectively; at data cutoff for the current study, mortality among the 99 included cases was 11%, which is similar to that in another recent 2019-nCoV report, they said.
The finding of greater risk among older men also has been seen with SARS-CoV and MERS-CoV, and the high rate among individuals with chronic diseases, mainly cerebrovascular disease, cardiovascular disease, and diabetes, also has been reported with MERS-CoV, they added.
“Our results suggest that 2019-nCoV is more likely to infect older adult males with chronic comorbidities as a result of the weaker immune functions of these patients,” they wrote.
Coinfection with bacteria and fungi occurred in some patients, particularly those with severe illness, and cultures most often showed A. baumannii, K. pneumoniae, A. flavus, C. glabrata, and C. albicans, and the findings of reduced absolute lymphocyte values in most patients suggests that “2019-nCoV might mainly act on lymphocytes, especially T lymphocytes, as does SARS-CoV,” they noted.
Given the rapid progression with ARDS and septic shock in some patients in this review, “early identification and timely treatment of critical cases is of crucial importance,” they said.
“Use of intravenous immunoglobulin is recommended to enhance the ability of anti-infection for severely ill patients, and steroids (methylprednisolone 1-2 mg/kg per day) are recommended for patients with ARDS, for as short a duration of treatment as possible,” they added.
Further, since some studies suggest that a substantial decrease in lymphocyte count indicates consumption of many immune cells by coronavirus, thereby inhibiting cellular immune function, damage to T lymphocytes might be “an important factor leading to exacerbations of patients,” they wrote, adding that “[t]he low absolute value of lymphocytes could be used as a reference index in the diagnosis of new coronavirus infections in the clinic.”
The MuLBSTA score also should be investigated to determine its applicability for predicting mortality risk in patients with 2019-nCoV infection, they added.
The current study is limited by its small sample size; additional studies are needed to include “as many patients as possible in Wuhan, in other cities in China, and even in other countries to get a more comprehensive understanding of 2019-nCoV,” they said.
The National Key R&D Program of China funded the study. The authors reported having no conflicts of interest.

Imaging showed bilateral pneumonia in 75% of cases, multiple mottling and ground-glass opacity in 14%, and pneumothorax in 1%. Organ function damage was present in a third of patients at admission: 17% had acute respiratory distress syndrome (ARDS) – including 11 patients who worsened quickly and died of multiple organ failure. Eight percent had acute respiratory injury, 3% had acute renal injury, 4% had septic shock, and 1% had ventilator-associated pneumonia, they said, noting that all cases were confirmed by real-time polymerase chain reaction.
A notable laboratory finding was reduced absolute lymphocyte counts in most patients, the investigators said.
All patients were treated in isolation and 76% received antiviral treatment with oseltamivir, ganciclovir, lopinavir, or ritonavir for 3-14 days (median, 3 days). Most patients also received antibiotic treatment, including a single antibiotic in 25% of cases and combination therapy in 45%, with most antibiotics used to cover “common pathogens and some atypical pathogens,” they said, adding that “when secondary bacterial infection occurred, medication was administered according to the results of bacterial culture and drug sensitivity.”
Cephalosporins, quinolones, carbapenems, tigecycline against methicillin-resistant Staphylococcus aureus, linezolid, and antifungal drugs were used, and duration ranged from 3 to 17 days (median, 5 days).
Nineteen patients also received steroid treatments.
As of Jan. 25, 31 patients had been discharged and 57 remained hospitalized. Of the 11 who died, the first 2 were a 61-year-old man and a 69-year-old man, each diagnosed with severe pneumonia and ARDS. The first experienced sudden cardiac arrest and died on admission day 11, and the second died of severe pneumonia, septic shock, and respiratory failure on admission day 9. Neither had underlying disease, but both had a long history of smoking, the investigators noted.
“The deaths of these two patients were consistent with the MuLBSTA score,” they wrote, explaining that the scoring system takes into account multilobular infiltration, lymphopenia, bacterial coinfection, smoking history, hypertension, and age.
Eight of the nine other patients who died had lymphopenia, seven had bilateral pneumonia, five were over age 60 years, three had hypertension, and one was a heavy smoker, they added.
Most coronavirus infections cause mild symptoms and have good prognosis, but some patients with the 2019-nCoV, which was identified Jan. 7 following the development of several cases of pneumonia of unknown etiology in Wuhan, develop fatal disease. The paucity of data regarding epidemiology and clinical features of pneumonia associated with 2019-nCoV prompted the current retrospective study at the center where the first cases were admitted, the investigators explained.
They noted that the sequence of 2019-nCoV “is relatively different from the six other coronavirus subtypes, including the highly pathogenic severe acute respiratory syndrome (SARS)-CoV and Middle East Respiratory Syndrome (MERS)-CoV, as well as the human coronaviruses (HCoV)-OC43, -229E, -NL63, and -HKU1 that induce mild upper respiratory disease, but can be classified as a betacoronavirus with evidence of human-to-human transmission.
Mortality associated with SARS-CoV and MERS-CoV have been reported as more than 10% and more than 35%, respectively; at data cutoff for the current study, mortality among the 99 included cases was 11%, which is similar to that in another recent 2019-nCoV report, they said.
The finding of greater risk among older men also has been seen with SARS-CoV and MERS-CoV, and the high rate among individuals with chronic diseases, mainly cerebrovascular disease, cardiovascular disease, and diabetes, also has been reported with MERS-CoV, they added.
“Our results suggest that 2019-nCoV is more likely to infect older adult males with chronic comorbidities as a result of the weaker immune functions of these patients,” they wrote.
Coinfection with bacteria and fungi occurred in some patients, particularly those with severe illness, and cultures most often showed A. baumannii, K. pneumoniae, A. flavus, C. glabrata, and C. albicans, and the findings of reduced absolute lymphocyte values in most patients suggests that “2019-nCoV might mainly act on lymphocytes, especially T lymphocytes, as does SARS-CoV,” they noted.
Given the rapid progression with ARDS and septic shock in some patients in this review, “early identification and timely treatment of critical cases is of crucial importance,” they said.
“Use of intravenous immunoglobulin is recommended to enhance the ability of anti-infection for severely ill patients, and steroids (methylprednisolone 1-2 mg/kg per day) are recommended for patients with ARDS, for as short a duration of treatment as possible,” they added.
Further, since some studies suggest that a substantial decrease in lymphocyte count indicates consumption of many immune cells by coronavirus, thereby inhibiting cellular immune function, damage to T lymphocytes might be “an important factor leading to exacerbations of patients,” they wrote, adding that “[t]he low absolute value of lymphocytes could be used as a reference index in the diagnosis of new coronavirus infections in the clinic.”
The MuLBSTA score also should be investigated to determine its applicability for predicting mortality risk in patients with 2019-nCoV infection, they added.
The current study is limited by its small sample size; additional studies are needed to include “as many patients as possible in Wuhan, in other cities in China, and even in other countries to get a more comprehensive understanding of 2019-nCoV,” they said.
The National Key R&D Program of China funded the study. The authors reported having no conflicts of interest.

A group of physicians in Wuhan, China, who are treating patients with the 2019 novel coronavirus have gone the extra mile to share their clinical experiences with colleagues around the world.
Nanshan Chen, MD, of Jinyintan Hospital, Wuhan, and his team conducted a retrospective study on 99 cases and, in very short order, published their initial findings in the Lancet online on Jan. 29. These findings could guide action in other cases and help clinicians all over the world create treatment plans for patients of the 2019-nCoV.
The findings show that and characteristics of those with fatal infections align with the MuLBSTA score – an early warning model for predicting viral pneumonia–related mortality, according to a case review.
Of 99 patients who presented with 2019-nCoV pneumonia at Jinyintan Hospital between Jan. 1 and Jan. 20, 67 were men, the mean age was 55.5 years, and 50 patients had chronic diseases.
“All the data of included cases have been shared with [the World Health Organization]. The study was approved by Jinyintan Hospital Ethics Committee and written informed consent was obtained from patients involved before enrollment when data were collected retrospectively,” the researchers noted.
Nearly half of the patients (49%) lived or worked near a specific seafood market, suggesting disease clustering.
Clinical manifestations affecting the majority of patients included fever and cough in 83% and 82% of patients, respectively. Other symptoms included shortness of breath in 31%, muscle aches in 11%, confusion in 9%, headache in 8%, sore throat in 5%, and rhinorrhea, chest pain, diarrhea, and nausea and vomiting in 1%-4% of patients, the investigators found.

Measles, scarlet fever among infectious diseases to watch for in 2020
ORLANDO – – leading into 2020, Justin Finch, MD, said at the ODAC Dermatology, Aesthetic, & Surgical Conference.
While group A streptococcus has declined over the past century, there has been “an unprecedented” resurgence in severe, invasive group A streptococcal infections and severe epidemics of scarlet fever worldwide, including in industrialized regions like the United Kingdom. Shedding some light on why this may be occurring, Dr. Finch referred to a recently published population-based molecular epidemiologic study identified a new dominant emm1UK lineage of Streptococcus pyogenes associated with such cases in England (Lancet Infect Dis. 2019 Nov;19(11):1209-18). This new lineage of S. pyogenes was genotypically distinct from other emm1 isolates and had greatly increased expression of the streptococcal pyrogenic exotoxin A, one of the exotoxins responsible for the clinical features of scarlet fever.
“We have not, to my knowledge, seen the strain yet in the United States,” said Dr. Finch, of Central Connecticut Dermatology in Cromwell. “Have it on your radar. With all of the worldwide travel patterns, I expect that you will see this in the United States at some point in the not-too-distant future.”
Also in 2019, promising data on the safety and effectiveness of the recombinant herpes zoster vaccine in immunocompromised patients became available for the first time. A randomized clinical trial published in JAMA of 1,846 patients who were immunosuppressed after autologous hematopoietic stem cell transplantation and received two doses of a recombinant zoster vaccine found that the patients had a reduced incidence of herpes zoster after a median follow-up of 21 months (JAMA. 2019 Jul 9;322[2]:123-33). The study found that the recombinant vaccine was both safe and effective in these immunocompromised patients, “so we can easily generalize this to our dermatology population as well,” Dr. Finch said. In comparing the live attenuated and recombinant vaccines, he noted the recombinant vaccine requires two doses but appears to be slightly more effective. “The number needed to treat to prevent [one case] of zoster is about half as high as that for the live vaccine, and most importantly for us is, it’s safe in immunocompromised patients.”
2019 also saw a record high in the number of measles cases in the United States, the highest since 1993, Dr. Finch pointed out. Most cases were seen in the area in and around New York City, but the percentage of people across the United States who are vaccinated against measles is below the threshold for herd immunity to protect immunocompromised patients. Measles requires a population vaccination rate of 94%, and less than half of U.S. counties in 2014 and 2015 reached that vaccination rate.
“Furthermore, if we look at that over the last 20 years, comparing the domestic measles cases to imported measles cases, we are increasingly breeding these measles epidemics right here at home, whereas they used to be imported from throughout the world,” said Dr. Finch. Patients with measles can be treated with vitamin A, he added, referring to a Cochrane review showing that 200,000 units of vitamin A given daily for 2 days decreased the mortality rate of measles by about 80%. Measles is on the Centers for Disease Control and Prevention’s list of reportable diseases, so should be reported to local health authorities, and will be followed up with confirmatory testing.
In 2019, a study examining herd protection of oral human papillomavirus infection in men and women compared the prevalence of oral HPV infection based on the 4 HPV types present in the quadrivalent HPV vaccine with 33 nonvaccine types from 2009 to 2016. There was no change in the prevalence of nonvaccine type oral HPV infections among men who were unvaccinated, but the prevalence of oral HPV infections because of the four strains in the quadrivalent HPV vaccine declined from 2.7% in 2009-2010 to 1.6% in 2015-2016 (JAMA. 2019 Sep 10;322[10]:977-9). Among unvaccinated women, the prevalence of nonvaccine- and vaccine-type oral HPV infections did not change between the two time periods.
“Notably, this only occurred in men,” Dr. Finch said. Herd immunity is being achieved in men “because we’re vaccinating all women, [but] we’re not seeing that herd immunity in women. Which begs the question: Why are we still vaccinating only half of our population?”
One study published in 2019 (Br J Dermatol. 2019 Nov;181[5]:1093-5) described a patient with CARD9 mutations, which predispose individuals to deep invasive infections – a disseminated Microsporum infection in this case, Dr. Finch said. “You shouldn’t see that,” he added, noting that these mutations are known to predispose individuals to severe Trichophyton infections and familial candidiasis.
“What I think is interesting about this is that, as we look forward to 2020, we’re going to increasingly see studies like this that are identifying specific mutations in our community that underlie a lot of these weird infections,” he added. “I wouldn’t be surprised if within the span of our careers, we find that a lot of those severe treatment-refractory reports that so commonly plague your everyday clinic have some underlying, specific immunity.”
Dr. Finch reported no relevant conflicts of interest.

REPORTING FROM ODAC 2020
FDA approves novel pandemic influenza vaccine
The Food and Drug Administration has approved the first and only adjuvanted, cell-based pandemic vaccine to provide active immunization against the influenza A virus H5N1 strain.
Influenza A (H5N1) monovalent vaccine, adjuvanted (Audenz, Seqirus) is for use in individuals aged 6 months and older. It’s designed to be rapidly deployed to help protect the U.S. population and can be stockpiled for first responders in the event of a pandemic.
The vaccine and formulated prefilled syringes used in the vaccine are produced in a state-of-the-art production facility built and supported through a multiyear public-private partnership between Seqirus and the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the U.S. Department of Health & Human Services.
“Pandemic influenza viruses can be deadly and spread rapidly, making production of safe, effective vaccines essential in saving lives,” BARDA Director Rick Bright, PhD, said in a company news release.
“With this licensure – the latest FDA-approved vaccine to prevent H5N1 influenza — we celebrate a decade-long partnership to achieve health security goals set by the National Strategy for Pandemic Influenza and the 2019 Executive Order to speed the availability of influenza vaccine. Ultimately, this latest licensure means we can protect more people in an influenza pandemic,” said Bright.
“The approval of Audenz represents a key advance in influenza prevention and pandemic preparedness, combining leading-edge, cell-based manufacturing and adjuvant technologies,” Russell Basser, MD, chief scientist and senior vice president of research and development at Seqirus, said in the news release. “This pandemic influenza vaccine exemplifies our commitment to developing innovative technologies that can help provide rapid response during a pandemic emergency.”
Audenz had FDA fast track designation, a process designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need.

“The approval of Audenz represents a key advance in influenza prevention and pandemic preparedness, combining leading-edge, cell-based manufacturing and adjuvant technologies,” Russell Basser, MD, chief scientist and senior vice president of research and development at Seqirus, said in the news release. “This pandemic influenza vaccine exemplifies our commitment to developing innovative technologies that can help provide rapid response during a pandemic emergency.”
Audenz had FDA fast track designation, a process designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need.

ACIP updates recommendations for adult vaccines
The Centers for Disease Control and Prevention has released an updated schedule for adult vaccines. The update includes changes regarding the administration of several vaccines, including those for influenza, human papillomavirus (HPV), hepatitis A and B, and meningitis B, as well as the pneumococcal 13-valent conjugate (PCV13) vaccine.
The schedule, revised annually by the Advisory Committee on Immunization Practices (ACIP) of the CDC, was simultaneously published online February 3, 2020, in the Annals of Internal Medicine and on the CDC website.
Perhaps the change most likely to raise questions is that concerning the PCV13 vaccine. “Owing to a decline in prevalence of the types covered by the PCV13 vaccine, this is no longer routinely recommended for all persons age 65 and older,” senior author Mark Freedman, DVM, MPH, of the immunization services division at the National Center for Immunization and Respiratory Disease, said in an interview.
For purposes of shared clinical decision, however, it should be discussed with previously unvaccinated seniors who do not have risk factors, such as an immunocompromising condition, a cerebrospinal fluid leak, or a cochlear implant.
“But the circumstances for use of the vaccine are not always clear even based on the detailed list of considerations provided, because it’s impossible to think of every conceivable combination of risk factors,” Mr. Freedman added.
Possible beneficiaries of this vaccine are vulnerable elderly people living in nursing homes and long-term care facilities and those living in or traveling to settings in which the rate of pediatric PCV13 uptake is low or zero.
All adults in this age group should continue to receive a single dose of the pneumococcal 23-valent polysaccharide vaccine.*
HPV
The advisory committee now recommends catch-up immunization for women and men through age 26 years (the previous cutoff for men was 21). And in another new recommendation, the ACIP advises considering vaccination for some patients aged 27-45 years who have not been adequately vaccinated.
“Most people ages 27-45 do not need vaccination, but some may benefit,” Mr. Freedman said. “For example, somebody who’s been in a prior long-term monogamous relationship and suddenly finds himself with a new sexual partner.”
“That makes very good sense for older people who haven’t been vaccinated and might continue to be exposed to HPV,” Daniel M. Musher, MD, a professor of medicine at Baylor College of Medicine and an infectious diseases physician at the Michael E. DeBakey Veterans Affairs Medical Center, both in Houston, said in an interview.
Here again, the ACIP advises taking a shared decision-making approach, with clinicians discussing the merits of vaccination in this and other scenarios with patients according to the talking points outlined in the HPV section.
Influenza, hepatitis A and B
For the 2019-2020 influenza season, routine influenza vaccination is recommended for all persons aged 6 months or older who have no contraindications. Where more than one appropriate option is available, the ACIP does not recommend any product over another.
Routine hepatitis A vaccination is recommended for all persons aged 1 year or older who have HIV infection regardless of their level of immune suppression.
For hepatitis B, a new addition to the list of vulnerable patients who may possibly benefit from vaccination is pregnant women at risk for infection or an adverse infection-related pregnancy outcome. Whereas older formulations are safe, the ACIP does not recommend the HepB-CpG (Heplisav-B) vaccine during pregnancy, owing to the fact that safety data are lacking.
Meningitis B
Individuals aged 10 years or older who have complement deficiency, who use a complement inhibitor, who have asplenia, or who are microbiologists should receive a meningitis B booster dose 1 year following completion of a primary series. After that, they should receive booster doses every 2-3 years for as long they are at elevated risk.
Vaccination should be discussed with individuals aged 16-23 years even if they are not at increased risk for meningococcal disease. Persons aged 10 years or older whom public health authorities deem to be at increased risk during an outbreak should have a one-time booster dose if at least 1 year has elapsed since completion of a meningitis B primary series.
Td/Tdap, varicella
The ACIP now recommends that either the Td or Tdap vaccine be given in cases in which currently just the Td vaccine is recommended; that is, for the 10-year booster shot as well as for tetanus prophylaxis in wound management and the catch-up immunization schedule, including that for pregnant women.
Vaccination against varicella should be considered for HIV-infected individuals who are without evidence of varicella immunity and whose CD4 counts are at least 200 cells/mL.
Dr. Musher, who was not involved in drafting the recommendations, takes issue generally with the addition of shared clinical decision making on vaccination. “Shared decision making is a problem for anyone practicing medicine. It places a terrible burden [on] the doctors to discuss these options with patients at great length. Most patients want the doctor to make the decision.”
In his view, this approach makes little sense in the case of the PCV13 vaccine because the strains it covers have disappeared from the population through the widespread vaccination of children. “But discussions are important for some vaccines, such as the herpes zoster vaccine, since patients can have a terrible reaction to the first dose and refuse to have the second,” he said.
Some of these new recommendations were released in 2019 after ACIP members met to vote on them in February, June, and October.
As in previous years, the schedule has been streamlined for easier reference. Physicians are reminded to closely read the details in the vaccine notes, as these specify who needs what vaccine, when, and at what dose.
The ACIP develops its recommendations after reviewing vaccine-related data, including the data regarding the epidemiology and burden of the vaccine-preventable disease, vaccine effectiveness and safety, the quality of evidence, implementability, and the economics of immunization policy.
The authors have received grants and expense payments from public and not-for-profit institutions. One coauthor has received fees from ACI Clinical for data and safety monitoring in an immunization trial. Dr. Musher has disclosed no relevant financial relationships.

Novel coronavirus cases now at 11; entry ban and quarantine measures begin
, Nancy Messonnier, MD, director of the National Center for Immunization and Respiratory Diseases, said during a Centers for Disease Control and Prevention press briefing.
Four of the new cases are in California, and one in Massachusetts. Although four of the new cases have recent travel history to Wuhan, China, the epicenter of the 2019-nCoV outbreak, the fifth is a close household contact of one of the other California patients, said Dr. Messonnier. This last case is the second instance of person-to-person spread of 2019-nCoV in the United States.
“We expect to find additional cases of the novel coronavirus in the United States,” she said. “We expect to see more cases of person-to-person spread among close contacts. And we continue to expect this will happen given the explosive nature of this outbreak in China.”
As of the morning of Feb. 3, 167 persons under investigation, or PUIs, for possible 2019-nCoV have tested negative for the virus, and an additional 82 PUIs have testing pending – this latter figure includes some tests that are still in transit to the CDC, said Dr. Messonnier.
During the briefing, Dr. Messonnier emphasized both the aggressive nature of the U.S. public health response and the rationale for quick and assertive action. “The goal of our public health response is to protect and contain,” she said. “Strong measures now may blunt the impact of this virus on the United States.”
She cited the intensity of transmission in Hubei Province, the expansion of transmission to other provinces in China, the expansion of cases outside of China, and sporadic ongoing deaths from 2019-nCoV as drivers of the aggressive U.S. public health response.
A presidential proclamation is currently in place that bars U.S. entry to foreign nationals who have visited mainland China within the past 14 days; the ban does not apply to travelers from Hong Kong and Macao. Immediate family members of U.S. citizens and individuals who have U.S. permanent resident status are exempted from the entry ban and will be allowed entry into the United States.
However, explained Dr. Messonnier, those who have traveled to China recently and are permitted entry will be subject to screening. All passengers with such recent travel will be directed to one of 11 U.S. airports set up to perform additional screening.
As of Feb 3, the list of airports includes:
- San Francisco International Airport in California.
- Los Angeles International Airport in California.
- Hartsfield-Jackson Atlanta International Airport in Georgia.
- Daniel K. Inouye International Airport in Hawaii.
- O’Hare International Airport in Illinois.
- Detroit Metropolitan Airport in Michigan.
- Newark Liberty International Airport in New Jersey.
- John F. Kennedy International Airport in New York.
- Dallas/Fort Worth International Airport in Texas.
- Washington Dulles International Airport in Virginia.
- Seattle-Tacoma International Airport in Washington.
Travelers who have been to Hubei Province in the previous 14 days will have an additional health assessment at which they will be screened for fever, cough, or difficulty breathing. Any American citizens or exempt individuals who are symptomatic would then be transferred for further medical evaluation. Asymptomatic travelers in this category will be subject to a mandatory 14-day quarantine near their point of entry, rather than continuing on to their final destinations.
Dr. Messonnier emphasized that the mandatory 14-day quarantine is specifically for Americans or exempt individuals returning from Hubei Province, adding that the CDC is presently working with individual states to determine the exact venues for quarantine.
American citizens and exempt individuals returning from other parts of mainland China will be routed to one of the 11 airports and will also receive additional health screening. Symptomatic individuals in this travel category would be referred for further evaluation before being able to complete their itinerary.
Asymptomatic American citizens and exempt individuals who are returning from mainland China – but not Hubei Province – will be allowed to travel on to their final destinations, but will be asked to stay home as much as possible and to monitor their health during the 14 days after their return.
The U.S. Department of State is bringing back more Americans from Wuhan province this week, and these individuals will also be kept under federal quarantine for 14 days.
“There are likely to be confirmed infections among returning travelers,” said Dr. Messonnier. “It is important to note that this strategy is not meant to catch every single traveler returning from China with novel coronavirus; given the nature of this virus and how it’s spreading, that would be impossible, but working together we can catch the majority of them.
“The goal here is to slow the entry of this virus into the United States,” she said, adding that the nation’s health care and public health systems stand on high alert to detect the virus in community settings. In response to questioning from the press, Dr. Messonnier defended the stringent quarantine measures, noting that they are in line with those taken by some other nations, and with the aggressive action being taken by the Chinese government itself. “These actions are science based and aimed at protecting the health of all Americans,” she said.
The real-time reverse transcription polymerase chain reaction (rRT-PCR) assay that the CDC has developed detects 2019-nCoV in both respiratory and serum specimens. Dr. Messonnier reported that the CDC is today filing an emergency use authorization (EUA) application to the U.S. Food and Drug Administration to expedite access to the assay for public health laboratories across the country. “This will greatly enhance our capacity to test for this virus,” she said, noting that EUA approval may come as soon as the end of this week.
Although the CDC is poised to send an expert team to China, it’s still awaiting favorable results from the international negotiations currently underway. “This is a horrible situation in China,” said Dr. Messonnier. “Our presence on the ground in China would be a help to China. ... Science should trump everything else; that’s what we’re hoping – that the scientific expertise of the global community can be brought to bear on the incredibly complicated, difficult situation that our colleagues in China are dealing with.”

Asymptomatic American citizens and exempt individuals who are returning from mainland China – but not Hubei Province – will be allowed to travel on to their final destinations, but will be asked to stay home as much as possible and to monitor their health during the 14 days after their return.
The U.S. Department of State is bringing back more Americans from Wuhan province this week, and these individuals will also be kept under federal quarantine for 14 days.
“There are likely to be confirmed infections among returning travelers,” said Dr. Messonnier. “It is important to note that this strategy is not meant to catch every single traveler returning from China with novel coronavirus; given the nature of this virus and how it’s spreading, that would be impossible, but working together we can catch the majority of them.
“The goal here is to slow the entry of this virus into the United States,” she said, adding that the nation’s health care and public health systems stand on high alert to detect the virus in community settings. In response to questioning from the press, Dr. Messonnier defended the stringent quarantine measures, noting that they are in line with those taken by some other nations, and with the aggressive action being taken by the Chinese government itself. “These actions are science based and aimed at protecting the health of all Americans,” she said.
The real-time reverse transcription polymerase chain reaction (rRT-PCR) assay that the CDC has developed detects 2019-nCoV in both respiratory and serum specimens. Dr. Messonnier reported that the CDC is today filing an emergency use authorization (EUA) application to the U.S. Food and Drug Administration to expedite access to the assay for public health laboratories across the country. “This will greatly enhance our capacity to test for this virus,” she said, noting that EUA approval may come as soon as the end of this week.
Although the CDC is poised to send an expert team to China, it’s still awaiting favorable results from the international negotiations currently underway. “This is a horrible situation in China,” said Dr. Messonnier. “Our presence on the ground in China would be a help to China. ... Science should trump everything else; that’s what we’re hoping – that the scientific expertise of the global community can be brought to bear on the incredibly complicated, difficult situation that our colleagues in China are dealing with.”
FROM A CDC PRESS BRIEFING
Don’t forget about the flu: 2019-2010 season is not over
Nationally, an estimated 5.7% of all outpatients visiting health care providers had influenza-like illness (ILI) for the week ending Jan. 25, which was up from 5.1% the previous week but still lower than the current seasonal high of 7.1% recorded during the week of Dec. 22-28, the CDC’s influenza division reported.
Another key indicator of influenza activity, the percentage of respiratory specimens testing positive, also remains high as it rose from 25.7% the week before to 27.7% for the week ending Jan. 25, the influenza division said. That is the highest rate of the 2019-2020 season so far, surpassing the 26.8% reached during Dec. 22-28.
Another new seasonal high involves the number of states, 33 plus Puerto Rico, at the highest level of ILI activity on the CDC’s 1-10 scale for the latest reporting week, topping the 32 jurisdictions from the last full week of December. Another eight states and the District of Columbia were in the “high” range with activity levels of 8 and 9, and no state with available data was lower than level 6, the CDC data show.
Going along with the recent 2-week increase in activity is a large increase in the number of ILI-related pediatric deaths, which rose from 39 on Jan. 11 to the current count of 68, the CDC said. At the same point last year, there had been 36 pediatric deaths.
Other indicators of ILI severity, however, “are not high at this point in the season,” the influenza division noted. “Overall, hospitalization rates remain similar to what has been seen at this time during recent seasons, but rates among children and young adults are higher at this time than in recent seasons.” Overall pneumonia and influenza mortality is also low, the CDC added.

Switching from TDF- to TAF-Containing Antiretroviral Therapy: Impact on Bone Mineral Density in Older Patients Living With HIV
Study Overview
Objective. To evaluate the effect of changing from tenofovir disoproxil fumarate (TDF) –containing antiretroviral therapy (ART) to tenofovir alafenamide (TAF) –containing ART in patients ages 60 years and older living with HIV.
Design. Prospective, open-label, multicenter, randomized controlled trial.
Setting and participants. The study was completed across 36 European centers over 48 weeks. Patients were enrolled from December 12, 2015, to March 21, 2018, and were eligible to participate if they were diagnosed with HIV-1; virologically suppressed to < 50 copies/mL; on a TDF-containing ART regimen; and ≥ 60 years of age.
Intervention. Participants (n = 167) were randomly assigned in a 2:1 ratio to ART with TAF (10 mg), elvitegravir (EVG; 150 mg), cobicistat (COB; 150 mg), and emtricitabine (FTC; 200 mg) or to continued therapy with a TDF-containing ART regimen (300 mg TDF).
Main outcome measures. Primary outcome measures were the change in spine and hip bone mineral density from baseline at week 48. Secondary outcome measures included bone mineral density changes from baseline at week 24, HIV viral suppression and change in CD4 count at weeks 24 and 48, and the assessment of safety and tolerability of each ART regimen until week 48.
Main results. At 48 weeks, patients (n = 111) in the TAF+EVG+COB+FTC group had a mean 2.24% (SD, 3.27) increase in spine bone mineral density, while those in the TDF-containing group (n = 56) had a mean 0.10% decrease (SD, 3.39), a difference of 2.43% (95% confidence interval [CI], 1.34-3.52; P < 0.0001). In addition, at 48 weeks patients in the TAF+EVG+COB+FTC group had a mean 1.33% increase (SD, 2.20) in hip bone mineral density, as compared with a mean 0.73% decrease (SD, 3.21) in the TDF-containing group, a difference of 2.04% (95% CI, 1.17-2.90; P < 0.0001).
Similar results were seen in spine and hip bone mineral density in the TAF+EVG+COB+FTC group at week 24, with increases of 1.75% (P = 0.00080) and 1.35% (P = 0.00040), respectively. Both treatment groups maintained high virologic suppression. The TAF+EVG+COB+FTC group maintained 94.5% virologic suppression at week 24 and 93.6% at week 48, as compared with virologic suppression of 100% and 94.5% at weeks 24 and 48, respectively, in the TDF-containing group. However, the TAF+EVG+COB+FTC group had an increase in CD4 count from baseline (56 cells/µL), with no real change in the TDF-containing group (–1 cell/µL). Patients in the TAF+EVG+COB+FTC group had a mean 27.8 mg/g decrease in urine albumin-to-creatinine ratio (UACR) versus a 7.7 mg/g decrease in the TDF-containing group (P = 0.0042). In addition, patients in the TAF+EVG+COB+FTC group had a mean 49.8 mg/g decrease in urine protein-to-creatinine ratio (UPCR) versus a 3.8 mg/g decrease in the TDF-containing group (P = 0.0042).
Conclusion. Patients 60 years of age or older living with virologically suppressed HIV may benefit from improved bone mineral density by switching from a TDF-containing ART regimen to a TAF-containing regimen after 48 weeks, which, in turn, may help to reduce the risk for osteoporosis. Patients who were switched to a TAF-containing regimen also had favorable improvements in UACR and UPCR, which could indicate better renal function.
The Centers for Disease Control and Prevention estimated that in 2018 nearly half of those living with HIV in the United States were older than 50 years.1 Today, the life expectancy of patients living with HIV on ART in developed countries is similar to that of patients not living with HIV. A meta-analysis published in 2017 estimated that patients diagnosed with HIV at age 20 beginning ART have a life expectancy of 63 years, and another study estimated that life expectancy in such patients is 89.1% of that of the general population in Canada.2,3 Overall, most people living with HIV infection are aging and at risk for medical conditions similar to persons without HIV disease. However, rates of osteoporosis in elderly patients with HIV are estimated to be 3 times greater than rates in persons without HIV.4 As a result, it is becoming increasingly important to find ways to decrease the risk of osteoporosis in these patients.
ART typically includes a nucleoside reverse transcriptase inhibitor (NRTI) combination and a third agent, such as an integrase strand inhibitor. Tenofovir is a commonly used backbone NRTI that comes in 2 forms, TDF (tenofovir disoproxil fumarate) and TAF (tenofovir alafenamide). Both are prodrugs that are converted to tenofovir diphosphate. TDF specifically is associated with an increased risk of bone loss and nephrotoxicity. The loss in bone mineral density is most similar to the bone loss seen with oral glucocorticoids.5 TDF has been shown to increase plasma levels of RANKL and tumor necrosis factor-α, leading to increased bone resorption.6 The long-term effects of TDF- versus TAF-containing ART on bone mineral density have, to our knowledge, not been compared previously in a randomized control study. The significance of demonstrating an increase in bone mineral density in the prevention of osteoporotic bone fracture in people living with HIV is less clear. A long-term cohort study completed in Japan looking at patients on TDF showed an increased risk of bone fractures in both older postmenopausal women and younger men.7 However, a retrospective cohort study looking at 1981 patients with HIV found no association between bone fractures and TDF.8
This randomized controlled trial used appropriate methods to measure the reported primary and secondary endpoints; however, it would be of benefit to continue following these patients to measure their true long-term risk of osteoporosis-related complications. In terms of the study’s secondary endpoints, it is notable that the patients maintained HIV viral suppression after the switch and CD4 counts remained stable (with a slight increase observed in the TAF-containing ART cohort).
In regard to the patient’s renal function, patients in the TAF group had significantly improved UACR and UPCR, which likely reflects improved glomerular filtration. Improved renal function is also increasingly important for patients with HIV, as up to 48.5% have some form of chronic kidney disease.9
Applications for Clinical Practice
This study shows that making the switch from TDF- to TAF-containing ART can lead to improved bone mineral density. We can extrapolate that switching may lead to a decreased risk of osteoporosis and osteoporosis-related complications, such as bone fracture, but this needs to be investigated in more detail. As demonstrated in this study, switching from a TDF- to a TAF-containing regimen can also lead to improved renal function while maintaining HIV viral suppression and CD4 counts.
Unfortunately, the regimen selected with TAF in this study (elvitegravir, cobicistat, and emtricitabine) includes cobicistat, which is no longer recommended as initial therapy due to its risk of drug-drug interactions, and elvitegravir, which has a lower barrier to resistance than other integrase strand inhibitors.10,11 The United States Department of Health and Human Services guidelines and the International Antiviral Society-USA Panel suggest using several other TAF-containing regimens for beginning or even switching therapy in older patients.10,11
When choosing between either a TAF- or a TDF-containing regimen to treat HIV infection in older patients, increasing evidence shows that using a TAF-containing ART regimen may be more beneficial for people living and aging with virologically suppressed HIV infection.

In terms of the study’s secondary endpoints, it is notable that the patients maintained HIV viral suppression after the switch and CD4 counts remained stable (with a slight increase observed in the TAF-containing ART cohort).
In regard to the patient’s renal function, patients in the TAF group had significantly improved UACR and UPCR, which likely reflects improved glomerular filtration. Improved renal function is also increasingly important for patients with HIV, as up to 48.5% have some form of chronic kidney disease.9
Applications for Clinical Practice
This study shows that making the switch from TDF- to TAF-containing ART can lead to improved bone mineral density. We can extrapolate that switching may lead to a decreased risk of osteoporosis and osteoporosis-related complications, such as bone fracture, but this needs to be investigated in more detail. As demonstrated in this study, switching from a TDF- to a TAF-containing regimen can also lead to improved renal function while maintaining HIV viral suppression and CD4 counts.
Unfortunately, the regimen selected with TAF in this study (elvitegravir, cobicistat, and emtricitabine) includes cobicistat, which is no longer recommended as initial therapy due to its risk of drug-drug interactions, and elvitegravir, which has a lower barrier to resistance than other integrase strand inhibitors.10,11 The United States Department of Health and Human Services guidelines and the International Antiviral Society-USA Panel suggest using several other TAF-containing regimens for beginning or even switching therapy in older patients.10,11
When choosing between either a TAF- or a TDF-containing regimen to treat HIV infection in older patients, increasing evidence shows that using a TAF-containing ART regimen may be more beneficial for people living and aging with virologically suppressed HIV infection.

HHS declares coronavirus emergency, orders quarantine
The federal government declared a formal public health emergency on Jan. 31 to aid in the response to the 2019 Novel Coronavirus (2019-nCoV). The declaration, issued by Health and Human Services Secretary Alex. M. Azar II gives state, tribal, and local health departments additional flexibility to request assistance from the federal government in responding to the coronavirus.
"While this virus poses a serious public health threat, the risk to the American public remains low at this time, and we are working to keep this risk low."*
2019-nCoV—the first such action taken by the Centers for Disease Control and Prevention in more than 50 years.
“This decision is based on the current scientific facts,” Nancy Messonnier, MD, director of the National Center for Immunization and Respiratory Diseases, said during a press briefing Jan. 31. “While we understand the action seems drastic, our goal today, tomorrow, and always continues to be the safety of the American public. We would rather be remembered for over-reacting than under-reacting.”
These actions come on the heels of the World Health Organization’s Jan. 30 declaration of 2019-nCoV as a public health emergency of international concern, and from a recent spike in cases reported by Chinese health officials. “Every day this week China has reported additional cases,” Dr. Messonnier said. “Today’s numbers are a 26% increase since yesterday. Over the course of the last week, there have been nearly 7,000 new cases reported. This tells us the virus is continuing to spread rapidly in China. The reported deaths have continued to rise as well. In addition, locations outside China have continued to report cases. There have been an increasing number of reports of person-to-person spread, and now, most recently, a report in the New England Journal of Medicine of asymptomatic spread.”
The quarantine of passengers will last 14 days from when the plane left Wuhan, China. Martin Cetron, MD, who directs the CDC’s Division of Global Migration and Quarantine, said that the quarantine order “offers the greatest level of protection for the American public in preventing introduction and spread. That is our primary concern. Prior epidemics suggest that when people are properly informed, they’re usually very compliant with this request to restrict their movement. This allows someone who would become symptomatic to be rapidly identified. Offering early, rapid diagnosis of their illness could alleviate a lot of anxiety and uncertainty. In addition, this is a protective effect on family members. No individual wants to be the source of introducing or exposing a family member or a loved one to their virus. Additionally, this is part of their civic responsibility to protect their communities.”
