Influenza

Cold and flu season came early in 2022.

On Nov. 4, 2022, the Centers for Disease Control and Prevention issued a Health Alert Network Health Advisory about early, elevated respiratory disease incidence caused by multiple viruses other than SARS-CoV-2.

Interseasonal spread of respiratory syncytial virus has continued in 2022, with RSV-associated hospitalizations increasing in the late spring and continuing throughout the summer and into the fall. In October, some regions of the country were seeing RSV activity near the peak seasonal levels typically observed in December and January.

Cases of severe respiratory infection in children who tested positive for rhinovirus or enterovirus spiked in August; further testing confirmed the presence of EV-D68 in some children. Rhinovirus and enterovirus continue to circulate and are isolated in hospitalized children with respiratory illness.

In some parts of the country, influenza cases have rapidly increased ahead of what we normally anticipate. According to preliminary estimates from the CDC, between Oct. 1 and Oct. 22, 880,000 people were sickened with flu, 420,000 people visited a health care provider for flu illness, and 6,900 people were hospitalized for flu. The cumulative hospitalization rate is higher than observed at this time of year in every previous flu season since 2010-2011. Hospitalization rates are highest in children aged 0-4 years and adults 65 years and older.

Of course, this report came as no surprise to pediatric health care providers. Many children’s hospitals had been operating at or over capacity for weeks. While a systematic assessment of the surge on children’s hospitals has not been published, anecdotally, hospitals from around the country have described record emergency department visits and inpatient census numbers. Some have set up tents or other temporary facilities to see ambulatory patients and have canceled elective surgeries because of a lack of beds.

There is no quick or easy solution to stem the tide of RSV-related or enterovirus/rhinovirus admissions, but many flu-related hospitalizations are vaccine preventable. Unfortunately, too few children are receiving influenza vaccine. As of the week ending Oct. 15, only about 22.1% of eligible children had been immunized. The American Academy of Pediatrics and the CDC recommend that all children are vaccinated, preferably by the end of October so they have time to develop immunity before influenza starts circulating. As it stands now, the majority of the nation’s children are facing a flu season without the benefits of vaccine.

There is still time to take steps to prevent this flu season from becoming one of the worst in recent memory. A strong provider recommendation for influenza vaccine is consistently associated with higher rates of vaccine acceptance. We need to recommend influenza vaccine to all eligible patients at every visit and in every setting. It will help if we can say it like we mean it. Some of us are tired of debating the merits of COVID-19 vaccine with families and may be leery of additional debates about flu. Some of us may just be tired, as many practices have already expanded office hours to care for the influx of kids with respiratory illness. On the heels of two atypical flu seasons, a few of us may be quietly complacent about the importance of flu vaccines for children.

Anyone in need of a little motivation should check out a paper recently published in Clinical Infectious Diseases that reinforces the value of flu vaccine, even in a year when there is a poor match between the vaccine and circulating viruses.

The 2019-2020 flu season was a bad flu season for children. Two antigenically drifted influenza viruses predominated and cases of influenza soared, resulting in the largest influenza epidemic in children in the United States since 1992. Pediatric Intensive Care Influenza Study investigators used a test-negative design to estimate the effectiveness of influenza vaccine in preventing critical and life-threatening influenza in children during that season. The good news: vaccination reduced the risk of critical influenza by 78% against H1N1pdm09 viruses that were well-matched to vaccine and by 47% against mismatched viruses. Vaccination was estimated to be 75% protective against antigenically drifted B-Victoria viruses. Overall vaccine effectiveness against critical illness from any influenza virus was 63% (95% confidence interval, 38%-78%).

While it might be tempting to attribute suboptimal immunization rates to vaccine hesitancy, ready availability remains an issue for some families. We need to eliminate barriers to access. While the AAP continues to emphasize immunization in the medical home, especially for the youngest infants, the 2022 policy statement suggests that vaccinating children in schools, pharmacies, and other nontraditional settings could improve immunization rates. To the extent feasible, we need to work with partners to support community-based initiatives and promote these to families who struggle to make it into the office.

Improving access is just one potential way to reduce health disparities related to influenza and influenza vaccination. Over 10 influenza seasons, higher rates of influenza-associated hospitalizations and intensive care unit admissions were observed in Black, Hispanic, and American Indian/Alaska Native people. These disparities were highest in children aged younger than 4 years and influenza-associated in-hospital deaths were three- to fourfold higher in Black, Hispanic, and Asian/Pacific Islander children, compared with White children. The reason for the disparities isn’t completely clear but increasing immunization rates may be part of the solution. During the 2020-2021 influenza season, flu immunization rates in Black children (51.6%) were lower than those seen in White (57.4%) and Hispanic children (58.9%).

The AAP’s Recommendations for Prevention and Control of Influenza in Children, 2022–2023, highlight a variety of evidence-based strategies to increase influenza immunization rates. These may provide a little inspiration for clinicians looking to try a new approach.

The Centers for Disease Control and Prevention is warning of an early surge in respiratory disease caused by multiple viruses. As influenza viruses, respiratory syncytial virus (RSV), SARS-CoV-2, and rhinovirus/enterovirus simultaneously circulate, the agency cautioned that this confluence of viral activity could strain the health care system, according to a CDC Health Network Alert advisory issued Nov. 4.

“This early increase in disease incidence highlights the importance of optimizing respiratory virus prevention and treatment measures, including prompt vaccination and antiviral treatment,” the alert stated.

The CDC reports that RSV activity is increasing nationally, but in some areas – such as the South and Mountain West – cases appear to be trending downward.

Influenza cases continue to climb, with the virus activity being the highest in the South, Mid-Atlantic, and the south-central West Coast, according to CDC data. “In fact, we’re seeing the highest influenza hospitalization rates going back a decade,” said José Romero, MD, director of the CDC’s National Center for Immunization and Respiratory Diseases, during a press briefing. The agency estimates that there have been 1.6 million illnesses, 13,000 hospitalizations, and 730 deaths from the flu so far this season. As of Nov. 4, there have been two pediatric deaths.

COVID-19 cases appear to have plateaued in the past three weeks, Dr. Romero said; however, the CDC expects that there will be “high-level circulation of SARS-CoV-2 this fall and winter,” the health alert stated.

The CDC advised that all eligible individuals aged 6-months or older should be vaccinated against COVID-19 and influenza. To protect against RSV-hospitalization, high-risk children should receive the monoclonal antibody drug palivizumab (Synagis). High-risk children include infants born before 29 weeks, children younger than age 2 with chronic lung disease or hemodynamically significant congenital heart disease, and children with suppressed immune systems or neuromuscular disorders.

Any patient with confirmed or suspected flu who is hospitalized, at higher risk for influenza complications, or who has a severe or progressive illness should be treated as early as possible with antivirals, such as oral oseltamivir (Tamiflu).

Patients with confirmed SARS-CoV-2 infection with increased risk of complications should also be treated with antivirals, such as nirmatrelvir and ritonavir (Paxlovid) or remdesivir (Veklury).

Patients should also be reminded to wash their hands frequently, cover coughs and sneezes, stay home when sick, and avoid close contact with people who are sick, the CDC advised.

“There’s no doubt that we will face some challenges this winter,” said Dawn O’Connell, HHS Assistant Secretary for Preparedness and Response, “but it’s important to remember that RSV and flu are not new, and we have safe and effective vaccines for COVID-19 and the flu.”

Just 3 weeks into the 2022-2023 flu season, the latest data from the Centers for Disease Control and Prevention’s Influenza Division suggest that the flu and respiratory syncytial virus are more than making up for the recent decline in COVID activity.

Outpatient visits for influenzalike illness (ILI), which includes influenza, SARS-CoV-2, and RSV, were higher after 3 weeks than for any of the previous five flu seasons: 3.3% of visits reported through the CDC’s Outpatient Influenza-like Illness Surveillance Network involved ILI as of Oct. 22. The highest comparable rate in the previous 5 years was the 1.9% recorded in late October of 2021, shortly after the definition of ILI was changed to also include illnesses other than influenza.

This season’s higher flu activity is in contrast to the previous two, which were unusually mild. The change, however, is not unexpected, as William Schaffner, MD, an infectious disease expert and professor of preventive medicine at Vanderbilt University, recently told CNN.

“Here we are in the middle of October – not the middle of November – we’re already seeing scattered influenza cases, even hospitalized influenza cases, around the country,” he said. “So we know that this virus is now spreading out in the community already. It’s gathering speed already. It looks to me to be about a month early.”

One indication of the mildness of the previous two flu seasons was the number of deaths, both pediatric and overall. Influenza-associated pediatric deaths had averaged about 110 per season over the previous eight seasons, compared with just 1 for 2020-2021 and 43 in 2021-2022. Overall flu deaths never reached 1% of all weekly deaths for either season, well below baseline levels for the flu, which range from 5.5% to 6.8%, CDC data show.
 

Other indicators of early severity

This season’s early rise in viral activity also can be seen in hospitalizations. The cumulative rate of flu-related admissions was 1.5 per 100,000 population as of Oct. 22, higher than the rate observed in the comparable week of previous seasons going back to 2010-2011, according to the CDC’s Influenza Hospitalization Surveillance Network.

A look at state reports of ILI outpatient visit rates shows that the District of Columbia and South Carolina are already in the very high range of the CDC’s severity scale, while 11 states are in the high range. Again going back to 2010-2011, no jurisdiction has ever been in the very high range this early in the season, based on data from the Outpatient Influenza-like Illness Surveillance Network.

A look at state reports of ILI outpatient visit rates shows that the District of Columbia and South Carolina are already in the very high range of the CDC’s severity scale, while 11 states are in the high range. Again going back to 2010-2011, no jurisdiction has ever been in the very high range this early in the season, based on data from the Outpatient Influenza-like Illness Surveillance Network.

Black Americans are 80% more likely to be hospitalized for the flu, compared with White Americans, according to new federal data.

Black, Hispanic, and American Indian/Alaska Native (AI/AN) adults in the United States also have had lower influenza vaccination rates, compared with their White counterparts, since 2010, researchers at the Centers for Disease Control and Prevention (CDC) revealed in a report.

The inequalities are the result of barriers to care, distrust of the medical system, and misinformation, the report said.

“We have many of the tools we need to address inequities and flu vaccination coverage and outcomes,” said CDC Acting Principal Deputy Director Debra Houry, MD, MPH, in a press call; “however, we must acknowledge that inequities in access to care continue to exist. To improve vaccine uptake, we must address the root causes of these ongoing disparities.”

The CDC has already reported early increases in flu activity in the United States, with the highest activity in the southeastern and south-central parts of the country. Experts also warn of a potentially more severe influenza season than in the previous 2 years. CDC officials emphasized that vaccination is the best protection against severe illness, hospitalization, and death from the flu. “Everyone should get vaccinated against flu today and encourage others and their community to get a flu vaccine for the best protection against flu this fall and winter,” Dr. Houry said.

In the recent report on disparities by community published October 18 in CDC Vital Signs, researchers looked at hospitalization rates from 2009 to 2022 and vaccination rates from 2010 to 2022 based on race and ethnicity using two national databases, the Influenza-Associated Hospitalization Surveillance Network and the Behavioral Risk Factor Surveillance System. All individuals included in the analysis were aged 18 years or older, and the 2020-2021 flu season was excluded from the analysis because of insufficient data.

Compared with those for White adults, hospitalization rates were 80% higher for Black adults, 30% higher for Hispanic adults, and 20% higher for AI/AN adults. While flu vaccination rates were similar in White and Asian adults (about 54%), coverage was lower in Black (42%), Hispanic (38%), AI/AN (41%), and other/multiracial (43%) adults. This disparity persisted even among individuals who had medical insurance, a personal health care provider, and a routine checkup within the last year.

“This report adds to the body of evidence that shows people from certain racial and ethnic minority groups have more severe outcomes at higher rates than White adults,” Carla Black, PhD, MPH, an epidemiologist at the CDC’s Immunization Services Division, said during the press call. While flu vaccines may not always prevent infection, people who do get sick after being vaccinated tend to have better outcomes, she added. The report noted that building trust, increasing access to vaccination services, and combating misinformation are important steps to increasing vaccine coverage in minority groups. 

While social distancing measures such as masking have made it difficult for the flu to spread, the relaxation of these safety measures could also lead to higher case counts. “We’ve had two mild flu seasons, and this means we might be ripe for a severe season,” Dr. Black said. “People haven’t had natural disease in 2 years, so there’s less natural immunity out there. People are going back to work. People are traveling again. All of these factors could contribute to us having a more severe flu season.”

Brent called his dad, Jeb Teichman, MD, in November 2019 saying he had felt sick for the past 3 days. The otherwise-healthy 29-year-old had a cough, sore throat, and was running a fever.

“It was what the CDC [Centers for Disease Control and Prevention] would call classic influenza-like illness,” Dr. Teichman said. “It was too late to start antivirals, so I gave him advice on symptomatic treatment. We texted the next day, and I was glad to hear that his fever was trending down and that he was feeling a little bit better.”

Two days later, his son called again. 

“He said he was having trouble breathing, and over the phone I could hear him hyperventilating.” The retired pediatrician and health care executive told his son to seek medical care. 

“Then I got the call that no parent wants to get.” 

Brent’s cousin Jake called saying he couldn’t wake Brent up.

“I called Jake back a few minutes later and asked him to hold up the phone,” Dr. Teichman said. “I listened to EMS working on my son, calling for round after round of many medications. He was in arrest and they couldn’t revive him.”

“To this day when I close my eyes at night, I still hear the beeping of those monitors.”

Brent had no health conditions to put him at higher risk for complications of the flu. “Brent was a wonderful son, brother, uncle, and friend. He had a passion for everything he did, and that included his chosen calling of the culinary arts but also included University of Kentucky sports,” Dr. Teichman said.

Brent planned to get a flu vaccine but had not done it yet. “In his obituary, we requested that, in lieu of flowers or donations, people go get their flu shot,” Dr. Teichman said.

“I’m here today to put a face on influenza,” Dr. Teichman said at a news briefing Oct. 4 on preventing the flu and pneumococcal disease, sponsored by the National Foundation for Infectious Diseases.
 

New survey numbers ‘alarming’

The NFID commissioned a national survey of more than 1,000 U.S. adults to better understand their knowledge and attitudes about the flu, pneumococcal disease, vaccines, and the impact of COVID-19.

“We were alarmed to learn that only 49% of U.S. adults plan to get their flu vaccine this season,” said Patricia A. “Patsy” Stinchfield, a registered nurse, NFID president, and moderator of the news briefing. “That is not good enough.”

In addition, 22% of people at higher risk for flu-related complications do not plan to get vaccinated this season. “That’s a dangerous risk to take,” Ms. Stinchfield said. 

An encouraging finding, she said, is that 69% of adults surveyed recognize that an annual flu vaccination is the best way to prevent flu-related hospitalizations and death. 

“So, most people know what to do. We just need to do it,” she said.

The top reason for not getting a flu shot in 2022 mentioned by 41% of people surveyed, is they do not think vaccines work very well. Another 39% are concerned about vaccine side effects, and 28% skip the vaccine because they “never get the flu.” 

The experts on the panel emphasized the recommendation that all Americans 6 months or older get the flu vaccine, preferably by the end of October. Vaccination is especially important for those at higher risk of complications from the flu, including children under 5, pregnant women, people with one or more health conditions, the immunocompromised, and Americans 65 years and older. 

Ms. Stinchfield acknowledged that the effectiveness of the flu vaccine varies season to season, but even if the vaccine does not completely match the circulating viruses, it can help prevent serious outcomes like hospitalization and death. One of the serious potential complications is pneumonia or “pneumococcal disease.” 

“Our survey shows that only 29% of those at risk have been advised to receive a pneumococcal vaccine,” Ms. Stinchfield said. “The good news is that, among those who were advised to get the vaccine, 74% did receive their pneumococcal vaccine,” she said. “This underscores a key point to you, my fellow clinicians: As health professionals, our recommendations matter.”
 

Higher doses for 65+ Americans

The CDC updated recommendations this flu season for adults 65 and older to receive one of three preferentially recommended flu vaccines, said CDC Director Rochelle Walensky, MD. The CDC is recommending higher-dose, stronger vaccines for older Americans “based on a review of the available studies, which suggested that in this age group, these vaccines are potentially more effective than standard-dose ... vaccines.”

During most seasons, people 65 and older bear the greatest burden of severe flu disease, accounting for most flu-related hospitalizations and deaths. 

“They are the largest vulnerable segment of our society,” Dr. Walensky said. 
 

What will this flu season be like?

Health officials in the flu vaccine business also tend to be in the flu season prediction business. That includes Dr. Walensky.

“While we will never exactly know what each flu season will hold, we do know that every year, the best way you can protect yourself and those around you is to get your annual flu vaccine,” she said while taking part remotely in the briefing. 

How severe will the flu season be in 2022-23? William Schaffner, MD, said he gets that question a lot. “Don’t think about that. Just focus on the fact that flu will be with us each year.

“We were a little bit spoiled. We’ve had two mild influenza seasons,” said Dr. Schaffner, medical director of NFID and a professor of infectious diseases and preventive medicine at Vanderbilt University, Nashville, Tenn. “I think with all the interest in COVID, people have rather forgotten about influenza. I’ve had to remind them that this is yet another serious winter respiratory virus. 

“As I like to say, flu is fickle. It’s difficult to predict how serious this next outbreak of influenza this season is going to be. We could look at what happened in the Southern Hemisphere,” he said. 

For example, Australia had the worst influenza season in the past 5 years, Schaffner said. “If you want a hint of what might happen here and you want yet another reason to be vaccinated, there it is.”

What we do know, Dr. Walensky said, is that the timing and severity of the past two flu seasons in the U.S. have been different than typical flu seasons. “And this is likely due to the COVID mitigation measures and other changes in circulating respiratory viruses.” Also, although last flu season was “relatively mild,” there was more flu activity than in the prior, 2020-21 season. 

Also, Dr. Walensky said, last season’s flu cases began to increase in November and remained elevated until mid-June, “making it the latest season on record.”

The official cause of Brent Teichman’s death was multilobar pneumonia, cause undetermined. “But after 30-plus years as a pediatrician ... I know influenza when I see it,” Dr. Teichman said.

“There’s a hole in our hearts that will never heal. Loss of a child is devastating,” he said. The flu “can take the life of a healthy young person, as it did to my son.

“And for all those listening to my story who are vaccine hesitant, do it for those who love you. So that they won’t walk the path that we and many other families in this country have walked.”

To prove their point, Dr. Teichman and Ms. Stinchfield raised their sleeves and received flu shots during the news briefing. 

“This one is for Brent,” Dr. Teichman said.

The influenza vaccine is linked to a significantly lower risk of ischemic stroke, with the reduced risk apparent at a population level even outside of flu season, in new findings that suggest the vaccine itself, and not just avoidance of the virus, may be beneficial.

“We postulate that influenza vaccination may have a protective effect against stroke that may be partly independent of influenza prevention,” study investigator Francisco J. de Abajo, MD, PhD, MPH, of the University of Alcalá, Madrid, said in an interview.

Jovanmandic/Thinkstock

“Although the study is observational and this finding can also be explained by unmeasured confounding factors, we feel that a direct biological effect of vaccine cannot be ruled out and this finding opens new avenues for investigation.”

The study was published online in Neurology.
 

‘Not a spurious association’

While there is a well-established link between seasonal influenza and increased ischemic stroke risk, the role of flu vaccination in stroke prevention is unclear.

In the nested case-control study, researchers evaluated data from primary care practices in Spain between 2001 and 2015. They identified 14,322 patients with first-time ischemic stroke. Of these, 9,542 had noncardioembolic stroke and 4,780 had cardioembolic stroke.

Each case was matched with five controls from the population of age- and sex-matched controls without stroke (n = 71,610).

Those in the stroke group had a slightly higher rate of flu vaccination than controls, at 41.4% versus 40.5% (odds ratio, 1.05).

Adjusted analysis revealed those who received flu vaccination were less likely to experience ischemic stroke within 15-30 days of vaccination (OR, 0.79) and, to a lesser degree, over up to 150 days (OR, 0.92).

The reduced risk associated with the flu vaccine was observed with both types of ischemic stroke and appeared to offer stroke protection outside of flu season.

The reduced risk was also found in subgroup comparisons in men, women, those aged over and under 65 years, and those with intermediate and high vascular risk.

Importantly, a separate analysis of pneumococcal vaccination did not show a similar reduction in stroke risk (adjusted OR, 1.08).

“The lack of protection found with the pneumococcal vaccine actually reinforces the hypothesis that the protection of influenza vaccine is not a spurious association, as both vaccines might share the same biases and confounding factors,” Dr. de Abajo said.
 

Anti-inflammatory effect?

Influenza infection is known to induce a systemic inflammatory response that “can precipitate atheroma plaque rupture mediated by elevated concentrations of reactive proteins and cytokines,” the investigators noted, and so, avoiding infection could prevent those effects.

The results are consistent with other studies that have shown similar findings, including recent data from the INTERSTROKE trial. However, the reduced risk observed in the current study even in years without a flu epidemic expands on previous findings.

“This finding suggests that other mechanisms different from the prevention of influenza infection – e.g., a direct biological effect – could account for the risk reduction found,” the investigators wrote.

In terms of the nature of that effect, Dr. de Abajo noted that, “at this stage, we can only speculate.

“Having said that, there are some pieces of evidence that suggest influenza vaccination may release anti-inflammatory mediators that can stabilize the atheroma plaque. This is an interesting hypothesis that should be addressed in the near future,” he added.
 

‘More than just flu prevention’

In an accompanying editorial, Dixon Yang, MD, and Mitchell S.V. Elkind, MD, agree that the findings point to intriguing potential unexpected benefits of the vaccine.

“This case-control study ... importantly suggests the influenza vaccine is more than just about preventing the flu,” they wrote.

Dr. Elkind said in an interview that the mechanism could indeed involve an anti-inflammatory effect.

“There is some evidence that antibiotics also have anti-inflammatory properties that might reduce risk of stroke or the brain damage from a stroke,” he noted. “So, it is plausible that some of the effect of the vaccine on reducing risk of stroke may be through a reduction in inflammation.”

Dr. Elkind noted that the magnitude of the reduction observed with the vaccine, though not substantial, is important. “The magnitude of effect for any one individual may be modest, but it is in the ballpark of the effect of other commonly used approaches to stroke prevention, such as taking an aspirin a day, which reduces risk of stroke by about 20%. But because influenza is so common, the impact of even a small effect for an individual can have a large impact at the population level. So, the results are of public health significance.”

The study received support from the Biomedical Research Foundation of the Prince of Asturias University Hospital and the Institute of Health Carlos III in Madrid. Dr. Elkind has reported receiving ancillary funding but no personal compensation from Roche for a federally funded trial of stroke prevention.

The influenza vaccine is linked to a significantly lower risk of ischemic stroke, with the reduced risk apparent at a population level even outside of flu season, in new findings that suggest the vaccine itself, and not just avoidance of the virus, may be beneficial.

“We postulate that influenza vaccination may have a protective effect against stroke that may be partly independent of influenza prevention,” study investigator Francisco J. de Abajo, MD, PhD, MPH, of the University of Alcalá, Madrid, said in an interview.

“Although the study is observational and this finding can also be explained by unmeasured confounding factors, we feel that a direct biological effect of vaccine cannot be ruled out and this finding opens new avenues for investigation.”

The study was published online in Neurology.

Attention parents: The nation’s leading pediatric medical society is urging you to make sure your children get a flu shot this fall to prevent and control the spread of the illness.

The American Academy of Pediatrics recently called on parents and caregivers to seek flu vaccines for their children as soon as they are available in the fall. The group is encouraging parents to catch up on all other vaccines for their children, too.

“As a pediatrician and a parent, I consider the flu vaccine as critical for all family members,” Kristina A. Bryant, MD, said in a statement about the academy’s recommendations. “We should not underestimate the flu, especially when other respiratory viruses like COVID-19 are circulating within our communities. Besides making your child miserable and wreaking havoc on your family’s routine, influenza can also be serious and even deadly in children.”

Only 55% of children aged 6 months to 17 years had been vaccinated against influenza as of early April – down 2% from the previous April – and coverage levels were 8.1% lower for Black children compared with non-Hispanic White children, according to the CDC. In the 2019-2020 flu season, 188 children in the United States died of the infection, equaling the high mark for deaths set in the 2017-2018 season, the agency reported.

American Academy of Pediatrics guidelines recommend children aged 6 months and older be vaccinated with the flu vaccine every year. Depending on the child’s age and health, they may receive either a shot, which has an inactive version of the flu virus, or the nasal spray, which has a weakened form of the virus. The academy has more information about the different vaccines.

Children aged 6-8 months who are getting flu vaccines for the first time should receive two doses at least 4 weeks apart. Pregnant women can get the flu vaccine any time in their pregnancy. Influenza vaccines are safe for developing fetuses, according to the academy.

The group stressed the importance of flu vaccines for high-risk and medically vulnerable children and acknowledged the need to end barriers to immunizations for all people, regardless of income or insurance coverage. In 2020, an estimated 16.1% of children in the United States were living in poverty, up from 14.4% in 2019, according to the U.S. Census Bureau.

Richard Martinello, MD, a professor of medicine and pediatric infectious diseases at Yale University, New haven, Conn., doesn’t expect to see a child hospitalized with respiratory syncytial virus (RSV) in the middle of summer. The illness, which can strike infants and older adults especially hard, is known as a “winter virus.”

But not this year. Over the last several weeks, he says, admissions for children with RSV have increased at the Yale New Haven Children’s Hospital. While the numbers aren’t large, they are out of the ordinary, he says, “because usually, at this time of year, we see zero. For lack of a better term, it’s weird.”

Likewise, William Schaffner, MD, a professor of infectious diseases at Vanderbilt University in Nashville, says RSV is on the rise there. Tennessee is one of 10 states taking part in a Centers for Disease Control and Prevention surveillance system that tracks influenza, RSV, and COVID-19.

He says RSV cases have risen by at least a third during the past week, including all age ranges. At this time of year, he says, “We aren’t supposed to have any RSV.”

RSV isn’t the only virus thriving out of season or otherwise acting strangely. Since the pandemic began, flu seasons have been out of whack – sometimes nearly nonexistent and other times extending well beyond “normal” seasons. Some experts say one influenza “B” strain may now be extinct, while others say it will be back.

Severe colds – what some call “super colds” – also seem to be on the rise in recent warm-weather months, although that evidence is mostly based on personal experience, not science.

Trying to explain these out-of-season variations has sparked much discussion among epidemiologists and virologists, Dr. Schaffner says, with debates ongoing about whether human behavior and habits or the seasons play a bigger role in the transmission of viral illness.

On top of that, scientists are also looking at the interactions between the SARS-CoV-2 virus that causes COVID-19 and other viruses. When people get hit with COVID-19 and other viruses at the same time, does that make COVID-19 more severe, or less?

Research is conflicting.
 

Summer of 2022: A repeat of 2021?

RSV. Most children contract the virus by age 2, and while it’s generally mild, about 58,000 children under age 5 years are hospitalized each year. During the pandemic, RSV cases decreased from January to April 2020, the CDC reported, and then remained at “historically low levels”: less than 1% positive RSV results a week, for the next year.

But cases began rising in April 2021.

“Last year, we did have an unusual summer,” Dr. Schaffner says. After lockdown ended, to everyone’s surprise, RSV infections rose.

That increase triggered a CDC health advisory in June 2021, telling doctors and caregivers about the increase in “interseasonal” RSV cases across parts of the Southern United States, recommending broader testing for RSV in patients who had a respiratory illness but tested negative for COVID.

Because of the reduced circulation of RSV during the winter of 2020 to 2021, the CDC warned, older infants and toddlers might have a higher risk of RSV since they weren’t exposed to typical levels of RSV for the previous 15 months.

What about 2022? “At the moment,” Dr. Schaffner says, “it looks like we are having a repeat [of 2021].”

On Twitter, other pediatricians, including those from Maine and Texas, have reported an increase in RSV cases this summer.

Influenza. From October 2020 until May 2021, flu activity was lower than during any previous flu season since at least 1997, according to the CDC.

In late 2021, researchers suggested that one line of influenza known as B/Yamagata may have become extinct.

The 2021-2022 flu season has been mild, the CDC says, but it has come in two waves, with the second wave lingering longer than previous ones. While flu activity is decreasing, last week the CDC said doctors should be alert to flu infections throughout the summer.

Colds. In reports on colds that aren’t based on science, several doctors say they are seeing more colds than usual in the summer, and they’re more severe than usual. According to the CDC, common coronaviruses and respiratory adenoviruses have been increasing since early 2021, and rhinoviruses since June 2020.

Behavior vs. seasons

In explaining the spread of viral respiratory diseases, infectious disease doctors consider two things. “One is that temperature and humidity in the winter favors longer survival of some viruses, leading to longer periods of possible transmission,” says Dean Blumberg, MD, a professor of pediatrics and chief of pediatric infectious disease at University of California Davis Health.

“The other is differences in human behavior, with people spending more time outside in the summer, which results in more distancing and [less] virus concentration due to very large air volume,” he says, and vice versa in winter.

What about the “super colds?” COVID-19 lockdowns and social distancing greatly reduced people’s exposure to common viruses like those that cause colds, says Neil A. Mabbott, PhD, a professor of immunopathology at the University of Edinburgh (Scotland).

“Immunity to these common cold viruses gained through natural infection is considered to last around 8 or 9 months or so,” he says. “Each winter, when we are exposed to the new circulating variants of these viruses, our immunity receives a natural boost.”

That explains why most people get a cold that’s relatively mild. But with all the pandemic lockdowns and the use of hand sanitizers, most people had limited exposure to other viruses, including the common cold. When people emerged from lockdown, the common cold viruses were beginning to circulate again.

“Our immune systems were less able to clear the infection than previously,” Dr. Mabbott says. “As a consequence, some may have experienced increased symptoms, giving the impression of being infected with a ‘super cold.’ ”

“The colds themselves are probably not different to those we got prepandemic,” says Ian Mackay, PhD, a virologist at the University of Queensland, Brisbane, Australia. “But there might be more of them. So I doubt they are ‘super colds’ as much as they are ‘super-perfect circumstances.’ ”

The colds themselves are probably not different to those we got prepandemic. But there might be more of them.

Those super-perfect circumstances, he says, include people gathering after lockdown; a lack of immunity in new babies; viruses that have remained, even if at low levels, but continue to mutate; and our waning immunity to the range of viruses we’d normally encounter.

While lack of exposure may partly explain why some viruses become rampant out of season, it’s likely not the only reason. For example, the reduced circulation of RSV in the population as a whole also may have reduced the transfer of immunity from mothers to infants, some researchers say, making those infants more vulnerable than usual.
 

Interactions of viruses

Another thing that may be driving the different behavior of viruses is that the SARS-CoV-2 virus could somehow be interacting with other respiratory viruses, Dr. Schaffner says. “And if so, what sort of interactions?”

Many researchers are looking into that, and how coinfections with other respiratory diseases, including the common cold and flu, may affect the course of COVID-19. Some studies have found that the T cells – a source of deeper, cellular immunity in people – generated after a common cold “may also provide cross-protection in some people against COVID-19.”

But another study found immunity against common cold–causing coronaviruses might make COVID-19 more severe.

When researchers in the United Kingdom studied nearly 7,000 patients infected with COVID-19, including 583 also infected with RSV, flu, or adenoviruses (causing flulike or coldlike illness), those with flu or adenovirus, compared with the others, were at higher risk of death.
 

To be continued …

Exactly how COVID-19 will be changing what we know of other viruses is yet to be determined, too.

Even before the pandemic, Dr. Martinello says, there were already some shifts in RSV. Florida, for instance, has an RSV season longer than the rest of the country, mimicking the pattern in the tropics.

Will the atypical patterns continue? “My guess is that this will settle out,” he says, with some sort of pattern developing. At this point, there are many unknowns. “We still can’t answer whether there will be some seasonality to COVID.”

“Our immune systems were less able to clear the infection than previously,” Dr. Mabbott says. “As a consequence, some may have experienced increased symptoms, giving the impression of being infected with a ‘super cold.’ ”

“The colds themselves are probably not different to those we got prepandemic,” says Ian Mackay, PhD, a virologist at the University of Queensland, Brisbane, Australia. “But there might be more of them. So I doubt they are ‘super colds’ as much as they are ‘super-perfect circumstances.’ ”

The colds themselves are probably not different to those we got prepandemic. But there might be more of them.

Those super-perfect circumstances, he says, include people gathering after lockdown; a lack of immunity in new babies; viruses that have remained, even if at low levels, but continue to mutate; and our waning immunity to the range of viruses we’d normally encounter.

While lack of exposure may partly explain why some viruses become rampant out of season, it’s likely not the only reason. For example, the reduced circulation of RSV in the population as a whole also may have reduced the transfer of immunity from mothers to infants, some researchers say, making those infants more vulnerable than usual.
 

Interactions of viruses

Another thing that may be driving the different behavior of viruses is that the SARS-CoV-2 virus could somehow be interacting with other respiratory viruses, Dr. Schaffner says. “And if so, what sort of interactions?”

Many researchers are looking into that, and how coinfections with other respiratory diseases, including the common cold and flu, may affect the course of COVID-19. Some studies have found that the T cells – a source of deeper, cellular immunity in people – generated after a common cold “may also provide cross-protection in some people against COVID-19.”

But another study found immunity against common cold–causing coronaviruses might make COVID-19 more severe.

When researchers in the United Kingdom studied nearly 7,000 patients infected with COVID-19, including 583 also infected with RSV, flu, or adenoviruses (causing flulike or coldlike illness), those with flu or adenovirus, compared with the others, were at higher risk of death.

Exactly how COVID-19 will be changing what we know of other viruses is yet to be determined, too.

Even before the pandemic, Dr. Martinello says, there were already some shifts in RSV. Florida, for instance, has an RSV season longer than the rest of the country, mimicking the pattern in the tropics.

Will the atypical patterns continue? “My guess is that this will settle out,” he says, with some sort of pattern developing. At this point, there are many unknowns. “We still can’t answer whether there will be some seasonality to COVID.”

Richard Martinello, MD, a professor of medicine and pediatric infectious diseases at Yale University, New haven, Conn., doesn’t expect to see a child hospitalized with respiratory syncytial virus (RSV) in the middle of summer. The illness, which can strike infants and older adults especially hard, is known as a “winter virus.”

But not this year. Over the last several weeks, he says, admissions for children with RSV have increased at the Yale New Haven Children’s Hospital. While the numbers aren’t large, they are out of the ordinary, he says, “because usually, at this time of year, we see zero. For lack of a better term, it’s weird.”

Likewise, William Schaffner, MD, a professor of infectious diseases at Vanderbilt University in Nashville, says RSV is on the rise there. Tennessee is one of 10 states taking part in a Centers for Disease Control and Prevention surveillance system that tracks influenza, RSV, and COVID-19.

He says RSV cases have risen by at least a third during the past week, including all age ranges. At this time of year, he says, “We aren’t supposed to have any RSV.”

RSV isn’t the only virus thriving out of season or otherwise acting strangely. Since the pandemic began, flu seasons have been out of whack – sometimes nearly nonexistent and other times extending well beyond “normal” seasons. Some experts say one influenza “B” strain may now be extinct, while others say it will be back.

Severe colds – what some call “super colds” – also seem to be on the rise in recent warm-weather months, although that evidence is mostly based on personal experience, not science.

Trying to explain these out-of-season variations has sparked much discussion among epidemiologists and virologists, Dr. Schaffner says, with debates ongoing about whether human behavior and habits or the seasons play a bigger role in the transmission of viral illness.

On top of that, scientists are also looking at the interactions between the SARS-CoV-2 virus that causes COVID-19 and other viruses. When people get hit with COVID-19 and other viruses at the same time, does that make COVID-19 more severe, or less?

Research is conflicting.
 

Summer of 2022: A repeat of 2021?

RSV. Most children contract the virus by age 2, and while it’s generally mild, about 58,000 children under age 5 years are hospitalized each year. During the pandemic, RSV cases decreased from January to April 2020, the CDC reported, and then remained at “historically low levels”: less than 1% positive RSV results a week, for the next year.

But cases began rising in April 2021.

“Last year, we did have an unusual summer,” Dr. Schaffner says. After lockdown ended, to everyone’s surprise, RSV infections rose.

That increase triggered a CDC health advisory in June 2021, telling doctors and caregivers about the increase in “interseasonal” RSV cases across parts of the Southern United States, recommending broader testing for RSV in patients who had a respiratory illness but tested negative for COVID.

Because of the reduced circulation of RSV during the winter of 2020 to 2021, the CDC warned, older infants and toddlers might have a higher risk of RSV since they weren’t exposed to typical levels of RSV for the previous 15 months.

What about 2022? “At the moment,” Dr. Schaffner says, “it looks like we are having a repeat [of 2021].”

On Twitter, other pediatricians, including those from Maine and Texas, have reported an increase in RSV cases this summer.

Influenza. From October 2020 until May 2021, flu activity was lower than during any previous flu season since at least 1997, according to the CDC.

In late 2021, researchers suggested that one line of influenza known as B/Yamagata may have become extinct.

The 2021-2022 flu season has been mild, the CDC says, but it has come in two waves, with the second wave lingering longer than previous ones. While flu activity is decreasing, last week the CDC said doctors should be alert to flu infections throughout the summer.

Colds. In reports on colds that aren’t based on science, several doctors say they are seeing more colds than usual in the summer, and they’re more severe than usual. According to the CDC, common coronaviruses and respiratory adenoviruses have been increasing since early 2021, and rhinoviruses since June 2020.

Behavior vs. seasons

In explaining the spread of viral respiratory diseases, infectious disease doctors consider two things. “One is that temperature and humidity in the winter favors longer survival of some viruses, leading to longer periods of possible transmission,” says Dean Blumberg, MD, a professor of pediatrics and chief of pediatric infectious disease at University of California Davis Health.

“The other is differences in human behavior, with people spending more time outside in the summer, which results in more distancing and [less] virus concentration due to very large air volume,” he says, and vice versa in winter.

What about the “super colds?” COVID-19 lockdowns and social distancing greatly reduced people’s exposure to common viruses like those that cause colds, says Neil A. Mabbott, PhD, a professor of immunopathology at the University of Edinburgh (Scotland).

“Immunity to these common cold viruses gained through natural infection is considered to last around 8 or 9 months or so,” he says. “Each winter, when we are exposed to the new circulating variants of these viruses, our immunity receives a natural boost.”

That explains why most people get a cold that’s relatively mild. But with all the pandemic lockdowns and the use of hand sanitizers, most people had limited exposure to other viruses, including the common cold. When people emerged from lockdown, the common cold viruses were beginning to circulate again.

“Our immune systems were less able to clear the infection than previously,” Dr. Mabbott says. “As a consequence, some may have experienced increased symptoms, giving the impression of being infected with a ‘super cold.’ ”

An experimental cancer drug could be promising for some people hospitalized with COVID-19, a new study shows.

The medication, called sabizabulin and given as a pill, reduced by half the risk of death among participants. It could be more effective than other drugs for those severely sick with COVID-19, The New York Times reports.

The manufacturer, Veru, is seeking emergency use authorization from the Food and Drug Administration. Hospitalized COVID-19 patients currently have only a few pharmaceutical options.

Sabizabulin blocks cells from building molecular cables that carry material from one part of a cell to another. It was created to fight cancer, because tumor cells need those cables (called microtubules) to grow quickly.

Researchers tried it against COVID-19 2 years ago, because viral replication also requires microtubules to bring pieces of new viruses together.

To participate in the small trial, patients had to be receiving oxygen or on a ventilator and at a high risk of dying from COVID-19, “with risk factors such as hypertension, advanced age or obesity,” the Times reported.

A total of 134 patients received the medicine; 70 got a placebo. Among those receiving sabizabulin, 20.2% died within 2 months; 45.1% of those who took the placebo died.

One infectious disease expert told the Times that the high mortality rate of those on the placebo could mean the study was too small to offer conclusive results.

“The 45% mortality rate in the control group jumps out at me as rather high,” said David Boulware, MD, of the University of Minnesota.

In an online statement the U.S. Centers for Disease Control and Prevention announced its decision to recommend higher-dose and adjuvanted influenza vaccines for people aged 65 years or older. Fluzone High-Dose Quadrivalent, Flublok Quadrivalent, and Fluad Quadrivalent flu vaccines are among those specified in the release.

The organization says that these higher-dose vaccines may be more effective for the aging population, who often have difficulty mounting a strong enough immune response to protect themselves against the flu virus. People older than 65 years struggle the most during flu season and have the highest proportion of hospitalizations and deaths from flu, according to the release.

But the CDC believes that higher-dose vaccines have the potential to better protect against that danger. One study, from The New England Journal of Medicine, reported that high-dose/adjuvanted vaccines prevented flu in older patients 24% better than did lower-dose/nonadjuvanted vaccines.

These types of vaccines work by creating a larger immune response than a standard vaccine dose. In particular, adjuvanted vaccines contain an extra ingredient within them that helps the immune system produce a stronger reaction to the vaccine. These may be things like aluminum salts, which signal the body to respond faster. Higher-dose vaccines similarly promote a stronger immune response by having more particles of the target virus in their mixture. In theory, this means the body will create an enhanced response to the vaccine. For example, a higher-dose vaccine may quadruple the amount of antigens, compared with the standard dose.

The hope is that this recommendation may increase vaccine use across the board, says José Romero, MD, the director of the CDC’s National Center for Immunization and Respiratory Diseases. As quoted in the CDC announcement, Dr. Romero said that this may help reduce racial inequities in access to flu vaccines. A 2019 meta-analysis concluded that Black and Hispanic people are around 30%-40% less likely to get the flu vaccine. So increasing the access to this medication “could help reduce health disparities by making these vaccines more available to racial and ethnic minority groups,” said Dr. Romero.

The decision, spearheaded by CDC Director Rochelle Walensky, MD, follows recommendations from the Advisory Committee on Immunization Practices, which presented on this topic during a June 22 meeting. It is now part of official CDC policy and will continue to be developed as the 2022-2023 flu season approaches.

In addition, the organization says they’ll reveal more details for their plan later this summer, in their Morbidity and Mortality Weekly Report (MMWR). For now, seniors should know that they should try to get the recommended high-dose vaccines, but if they can’t, then a standard dose of whatever their provider has on hand will do.

At this point, there is still no specific vaccine recommendation for people aged under 65 years. The CDC historically avoids specifying one type of vaccine over another and says each should still be effective in younger patients.
