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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Delayed care

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

What are patients alleging?

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

How to protect yourself against suits

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Weekly new hospitalizations for COVID-19 have climbed for the fourth straight week. 

Nationwide, 10,320 people were hospitalized during the week ending Aug. 5, up from 9,026 the week prior, which is about a 14% week-over-week increase, according to newly updated Centers for Disease Control and Prevention figures. Hospitalizations reached an all-time low of about 6,300 per week in July.

The CDC stopped tracking the number of people infected by the virus earlier in 2023, and now relies on hospitalization data to gauge the current impact of COVID-19. 

“We have to remember that we’re still dealing with numbers that are far less than what we’ve seen for the pandemic,” John Brownstein, PhD, a professor of biomedical informatics at Harvard Medical School, Boston, told ABC News. “We have to zoom out to look at our experience for the entire pandemic, to understand that what we’re dealing with now is far from any crisis that we’ve experienced with previous waves.”

The current predominant strain remains EG.5, and experts believe it is not more severe or more contagious than other recent variants.  

Dr. Brownstein told ABC News that one reason for the concern about rising COVID metrics, despite their overall low levels, is that a surge occurred in the summer of 2021 with the dangerous Delta variant.

“But each new variant so far that has come through has subsequently had less of a population impact,” he said. “Now, is it possible we may see one in the future that is worthy, a real concern? Absolutely. But overall, we’ve seen a dampening of effect over the last several variants that have come through.”

The newest version of the COVID-19 vaccine will be available by the end of September, according to the Centers for Disease Control and Prevention. 

The updated vaccine still needs final sign-offs from the Food and Drug Administration and the CDC.

“We anticipate that they are going to be available for most folks by the third or fourth week of September,” Director Mandy Cohen, MD, MPH, said on a podcast hosted by former White House COVID adviser Andy Slavitt. “We are likely to see this as a recommendation as an annual COVID shot, just as we have an annual flu shot. I think that will give folks more clarity on whether they should get one or not.”

For people who are considering now whether they should get the currently available COVID vaccine or wait until the new one comes out, Dr. Cohen said that depends on a person’s individual risk. People who are 65 or older or who have multiple health conditions should go ahead and get the currently available shot if it’s been more than 6-8 months since their last dose. For all other people, it’s OK to wait for the new version.

Analysts expect low demand for the updated vaccine. About 240 million people in the United States got at least one dose when vaccines first became available in 2021, Reuters reported, but that number dropped to less than 50 million getting the most updated shot in the fall of 2022.

“Take a look at what happened last winter. It was 50 million in the U.S., and it seems likely to be lower than that, given that there’s less concern about COVID this year than last year,” Michael Yee, a health care industry analyst for the firm Jefferies, told Reuters.

Dr. Cohen noted during the podcast that the recent uptick in virus activity should be taken in context. 

“What we’re seeing right now in August of 2023 are small increases of folks getting COVID. We are still at some of the lowest hospitalizations that we’ve been at in the past 3 years,” she said. “Even a 10% increase on a very, very small number is still very small. My level of concern continues to be low.”

Long COVID most often strikes seniors and adults, but children are also affected, even though they get less attention, new research shows.

Experts noted that the disease poses particular challenges for children and the doctors who treat them.

Parents and doctors need to be on the lookout for symptoms of long COVID in children and teens that might be easily missed or misdiagnosed, according to physicians and family groups.

Children are at lower risk for contracting COVID and often experience milder symptoms. But the virus is now widespread, and a recent study found that around 16% of pediatric patients with COVID go on to develop symptoms that last more than 3 months – the working definition of long COVID.

Parents and doctors are calling for more studies and more awareness.

Diane Sheehan, who lives outside Charlotte, N.C., says she was an active person and is now permanently disabled from long COVID. Her teenage son has it too and is still recovering.

He contracted COVID after a school event, she said. He had a mild case, but then he started experiencing dizziness and would even experience loss of consciousness when he stood up suddenly. After he contracted the virus a second time, he was bedridden for 8 months.

The staff at Hackensack Meridian Health, a pediatric long COVID clinic in New Jersey, has been working with area schools to help teachers and school nurses recognize possible long COVID in children and young people. The clinic is one of about a dozen in the United States that specializes in pediatric cases.

Katherine Clouser, MD, a pediatric hospital medicine specialist, has been with the clinic since it opened in 2021, and she’s seen a steady flow of patients. Some get better, but she sees a few new cases each week.

“We are seeing children who are having a difficult time returning to school and sports,” she said.

The clinic is having success with a mix of approaches, including intensive rehabilitation, talk therapy, and some off-label use of nirmatrelvir (Paxlovid), an antiviral now being studied as a treatment for long COVID through a National Institutes of Health clinical trials initiative that was announced last month.

Treatment depends on symptoms and is determined on a case-by-case basis, Dr. Clouser said.

Families of her patients are grateful, she added.

“We hear a lot of parents who were desperate for someone to believe them – or someone who knows about it,” she said.

A recent review of more than 30 studies with about 15,000 participants concluded that 16.2% (95% confidence interval, 8.5%-28.6%) of the pediatric participants experienced one or more persistent symptoms of long COVID at least 3 months after acute infection.

Estimates of the number of children and youth with long COVID have varied widely. A 2022 study put the number at more than 25% of cases, but the American Academy of Pediatrics notes that estimates of the percentage of children infected with SARS-CoV-2 who go on to have long COVID range from 2% to 66%.

The federal Recover Initiative has enrolled more than 10,000 children and youth – a number it plans to double – and studies of electronic health records are underway. The Recover pediatric team is also setting up a cohort that they plan to follow into 2025.

Some clinics are having luck treating young people with approaches ranging from special diets to off-label medication.

David W. Miller, MD, who runs the long COVID clinic at the UH Rainbow Babies and Children’s Hospital, Cleveland, said he’s seen about 250 patients.

A warning sign of long COVID in children is profound fatigue, he said.

“It’s the most common symptom,” Dr. Miller said. “They feel like they have the flu all the time.”

Many also experience orthostatic hypotension on standing, triggering dizziness.

He said his team targets symptom groups. Initial management consists of a diet without sugar or refined carbohydrates. Skipping pasta and sweets can be hard for young people, but Dr. Miller said sometimes the diet alone helps.

Many have vitamin D and iron deficiencies. Others need help getting a good night’s sleep. He’s treated 50 with off-label low-dose naltrexone.

Some people with long COVID – both young and old – complain about being misdiagnosed as having depression. Dr. Miller says he see a lot of anxiety – some situational and some biochemical – in pediatric patients. But he cautions doctors not to treat their illness solely as a mental health problem.

His advice: If a young person or child experiences a major change in his or her regular level of functioning or has multiple COVID symptoms that don’t go away after several months, parents and doctors should consider long COVID as a possible cause.

Dr. Miller said most of his patients get better over time with some treatments: “We see improvement in the majority of kids who can stick to the regimen,” such as a sugar-free diet, supplements, and adequate sleep. Recovery has been slow and incomplete for Diane Sheehan and her son. She was training as a permanent make-up artist, she said, but now has hand tremors that make work impossible.

She has found doctors who treat some of her symptoms with antihistamines, and her son has benefited from physical therapy.

But for now, her son is passing on a scholarship he was awarded to attend North Carolina State University this year. Instead, he’s living at home and going to a local college.

Ms. Sheehan urges parents to be on the alert for signs that their children might have long COVID, which can be confused with many other conditions.
