As COVID-19 cases and hospitalizations continue to decline across the United States, all states but one -- Hawaii -- have dropped their mask mandates or have announced plans to do so in coming weeks.

Retailers and cruises are following along, with Apple and Target stores lifting their own mask mandates this week. Cruise lines such as Norwegian and Royal Caribbean International have said mask requirements will be relaxed for vaccinated passengers, according to the Washington Post.

But guidance from the Centers for Disease Control and Prevention hasn’t changed even as the Omicron variant recedes across the country. Vaccinated people should wear masks when indoors in areas of “substantial or high transmission,” which still covers more than 95% of the country, according to a CDC map.

As daily cases continue to fall, the CDC is reviewing its recommendations, Rochelle Walensky, MD, the CDC director, said during a briefing last week.

“We want to give people a break from things like mask-wearing, when these metrics are better, and then have the ability to reach for them again should things worsen,” she said.

As states relax mask rules, county and city officials are now deciding what to do in their jurisdictions. Vaccinated residents in Los Angeles County may soon be able to go maskless in indoor settings that check for proof of vaccination, according to the Los Angeles Times.

Chicago will also end its mask and COVID-19 vaccine mandates for public places such as restaurants Feb. 28, according to the Chicago Tribune. Illinois will end a statewide indoor mask mandate on the same day. Masks will still be required in health care settings and public transmit.

State and local school boards are debating their mask policies as well. The Maryland State Board of Education voted Feb. 22 to allow local school districts to decide whether students must wear face coverings in school, according to the Associated Press. The update will take effect on March 1 if approved by a Maryland General Assembly committee that oversees the rule.

In New York, state officials have begun lifting mask rules. At the same time, 58% of New York voters want to see early March data before school mask mandates are ended, according to a new poll, released Feb. 22 by the Siena College Research Institute. About 45% of those polled said the state’s indoor public mask mandate should also still be in place.

The debate about wearing masks in schools will likely continue, especially as districts get caught between health authorities and parents, according to the Wall Street Journal. District officials in several states are receiving hundreds of emails daily from both sides, with parents calling for mask rules to end or saying that requirements should remain in place for now to keep kids safe.

American health care workers have remained resilient during the pandemic but are feeling the ongoing strain, with 23% saying they are likely to leave the field in the near future, according to a new poll.

About half of the respondents to the poll from USA Today/Ipsos reported feeling “burned out,” 43% said they were “anxious,” and 21% said they were “angry” about politics and abuse from patients and families.

“We’re trying to help people here, and we are getting verbally and physically abused for it,” Sarah Fried, a nurse in California who responded to the survey, told USA Today in a follow-up interview.

“Early in this pandemic, people were clapping for us and calling us heroes,” she said. “And what happened to that? What happened to them appreciating what nurses are doing?”

The poll was done Feb. 9-16 among 1,170 adults in the U.S. health care industry, including doctors, nurses, paramedics, therapists, home health aides, dentists, and other medical professionals.

A large majority of workers still reported being satisfied with their jobs, although that optimism has declined somewhat since early 2021 when the COVID-19 vaccine rollout was underway. About 80% of those in the recent poll said they were somewhat or very satisfied with their current job, which is down from 89% in an April 2021 poll from Kaiser Family Foundation/the Washington Post.

Most health care workers reported feeling “hopeful” (59%), “motivated” (59%), or “optimistic” (56%) about going to work. But “hopeful” is down from 76% and “optimistic” is down from 67%, compared with last year.

If they could pick a career over again, about 16% disagreed with the statement, “I would still decide to go into health care,” and 18% said they didn’t know how they felt about it.

“The pandemic has actually made me realize how important this career is and how I really do make a difference. I still love it,” Christina Rosa, a mental health counselor in Massachusetts, told USA Today.

During the pandemic, about 66% of those polled said they had treated a COVID-19 patient, which increased to 84% among nurses and 86% among hospital workers. Among those, 47% reported having a patient who died from COVID-19, including 53% of nurses and 55% of hospital workers.

What’s more, 81% of those who treated COVID-19 patients have cared for unvaccinated patients. Among those, 67% said their patients continued to express skepticism toward COVID-19 vaccines, and 38% said some patients expressed regret for not getting a vaccine. Beyond that, 26% said unvaccinated patients asked for unproven treatments, and 30% said the patient or family criticized the care they received.

Regarding coronavirus-related policy, most Americans working in health care expressed skepticism or criticism of the nation’s handling of the pandemic. About 39% agreed that the American health care system is “on the verge of collapse.”

Only 21% said the pandemic is mostly or completely under control. About 61% don’t think Americans are taking enough precautions to prevent the spread of the coronavirus.

Health care workers were slightly positive when it comes to the Centers for Disease Control and Prevention (54% approve, 34% disapprove), divided on the Biden administration (41% approve, 40% disapprove), and critical of the news media (20% approve, 61% disapprove) and the American public (18% approve, 68% disapprove).

Broadly, though, health care workers support public health efforts. About 85% back measures that provide N95 masks, and 83% back measures that provide COVID-19 tests.

About 80% of people infected with Zika virus show no symptoms, and that’s particularly problematic during pregnancy. The infection can cause birth defects and is the origin of numerous cases of microcephaly and other neurologic impairments.

The large amount of Aedes aegypti mosquitoes in Brazilian cities, in addition to social and political problems, facilitated the spread of Zika to the point that the country recorded its highest number of congenital Zika syndrome notifications from 2015 to 2018. Since then, researchers have investigated the extent of the problem.

One of the most compelling findings about the dramatic legacy of Zika in Brazil was published Feb. 24 in The New England Journal of Medicine: After tracking 11,481,215 children born alive in Brazil up to 36 months of age between the years 2015 and 2018, the researchers found that the mortality rate was about 12 times higher among children with congenital Zika syndrome in comparison to children without the syndrome. The study is the first to follow children with congenital Zika syndrome for 3 years and to report mortality in this group.

“This difference persisted throughout the first 3 years of life,” Enny S. Paixão, PhD, of the London School of Hygiene and Tropical Medicine, and Fiocruz-Bahia’s Instituto Gonçalo Moniz, in Brazil, said in an interview.

At the end of the study period, the mortality rate was 52.6 deaths (95% confidence interval, 47.6-58.0) per 1,000 person-years among children with congenital Zika syndrome and 5.6 deaths (95% CI, 5.6-5.7) per 1,000 person-years among those without the syndrome. The mortality rate ratio among children with congenital Zika syndrome, compared with those without it, was 11.3 (95% CI, 10.2-12.4). Data analysis also showed that the 3,308 children with the syndrome were born to mothers who were younger and had fewer years of study when compared to the mothers of their 11,477,907 counterparts without the syndrome.

“If the children survived the first month of life, they had a greater chance of surviving during childhood, because the mortality rates drop,” said Dr. Paixão. “In children with congenital Zika syndrome, this rate also drops, but slowly. The more we stratified by period – neonatal, post neonatal, and the period from the first to the third year of life – the more we saw the relative risk increase. After the first year of life, children with the syndrome were almost 22 times more likely to die compared to children without it. It was hard to believe the data.” Dr. Paixão added that the mortality observed in this study is comparable with the findings of previous studies.

In addition to the large sample size – more than 11 million children – another unique aspect of the work was the comparison with healthy live births. “Previous studies didn’t have this comparison group,” Dr. said Paixão.

Perhaps the major challenge of the study, Dr. Paixão explained, was the fragmentation of the data. “In Brazil we have high-quality data systems, but they are not interconnected. We have a database with all live births, another with mortality records, and another with all children with congenital Zika syndrome. The first big challenge was putting all this information together.”

The solution found by the researchers was to use data linkage – bringing information about the same person from different data banks to create a richer dataset. Basically, they linked the data from the live births registry with the deaths that occurred in the studied age group plus around 18,000 children with congenital Zika syndrome. This was done, said Dr. Paixão, by choosing some identifying variables (such as mother’s name, address, and age) and using an algorithm that evaluates the probability that the “N” in one database is the same person in another database.

“This is expensive, complex, [and] involves super-powerful computers and a lot of researchers,” she said.

The impressive mortality data for children with congenital Zika syndrome obtained by the group of researchers made it inevitable to think about how the country should address this terrible legacy.

“The first and most important recommendation is that the country needs to invest in primary care, so that women don’t get Zika during pregnancy and children aren’t at risk of getting the syndrome,” said Dr. Paixão.

As for the affected population, she highlighted the need to deepen the understanding of the syndrome’s natural history to improve survival and quality of life of affected children and their families. One possibility that was recently discussed by the group of researchers is to carry out a study on the causes of hospitalization of children with the syndrome to develop appropriate protocols and procedures that reduce admissions and death in this population.

Big Vegetable has lied to us all

Hear this, children of the world: Your parents have betrayed you. They tell you day in and day out that vegetables are necessary, that they’re healthy, that you need them, but it is not the truth. Behind their foul taste is nothing but empty lies.

Okay, before we get a full-blown child rebellion on our hands, let’s reel things in. Eating vegetables has many benefits, and will help prevent many nasty medical conditions, such as diabetes or cancer. However, cardiovascular disease is not among them.

nneem/Pixabay

For their study published in Frontiers in Nutrition, researchers analyzed the diet, lifestyle, and medical history of nearly 400,000 U.K. adults over a 5-year period, finding that 4.5% developed heart disease and that the average adult consumed about 5 tablespoons of vegetables per day. Those who consumed the most vegetables had a reduction in heart disease incidence of about 15%, compared with those who ate the least.

Hang on, you’re thinking, we just said that vegetables didn’t prevent cardiovascular disease. But the data show otherwise! Ah, but the data are unadjusted. Once the researchers took socioeconomic status, information level, and general lifestyle into account, that benefit disappeared almost completely. The benefit seems to come not from the vegetables themselves, but from being able to afford better food and medical care in general.

The researchers were quick to note the other benefits of eating vegetables, and that people should probably keep eating those five servings a day. But we’re onto you, scientists. You can’t fool us with your vegetable-based lies. Unless we’re talking about pizza. Pizza is the best vegetable.
 

The good old days of surgery?

Modern surgical instruments, techniques, and technological innovations are amazing. It’s hard to imagine what surgery was like before laparoscopes came along, or x-ray machines, or even anesthesia. But those days weren’t really that long ago. Modern anesthesia, after all, dates back to just 1846. We’ve got socks almost that old.

But suppose we go back even further … say 5,300 years. Older than the oldest sock. Scientists studying a funerary chamber in Burgos, Spain, which was built in the 4th millennium B.C., have come across what looks like “the first known radical mastoidectomy in the history of humankind,” Sonia Díaz-Navarro of the University of Valladolid (Spain) and associates wrote in Scientific Reports.

One of the skulls they uncovered shows signs of trepanation. “Despite the [evidence] of cut marks, it is difficult to conclude the type of tool used to remove the bone tissue, most likely a sharp instrument with a circular movement,” they investigators said.

What is clear, though, is that the patient survived the surgery, because there is evidence of bone regeneration at the surgical sites. Sites? “Based on the differences in bone remodelling between the two temporals, it appears that the procedure was first conducted on the right ear, due to an ear pathology sufficiently alarming to require an intervention, which this prehistoric woman survived,” they explained.

The same procedure was then performed on the left ear, “but whether this was performed shortly after the right ear, or several months or even years later can’t be concluded from the existing evidence,” IFL Science reported.

Located nearby was a small section of tree bark with some scratches on it. That, ladies and gentlemen, was the first prior authorization form.
 

I hate that song, with reason

Do you have a favorite song? You may have a million reasons for loving that song. And past research can tell you why. But it’s only in a recent study that researchers were able to tell you why you dislike a song. And you know the song we’re talking about.

MPI for Empirical Aesthetics

Dislike breaks down into three major categories of rationale: subject-related reasons (how the song makes you feel emotionally and/or physically), object-related reasons (the lyrics or composition), and social reasons (do you relate to this?). Researchers at the Max Planck Institute for Empirical Aesthetics in Frankfurt, Germany, interviewed 21 participants and asked them to come up with a prepared list of music that they disliked and why they didn’t like it. And there was a lot that they didn’t like: 277 dislikes worth, to be exact.

“The most often mentioned type of dislike was musical style, followed by artist and genre,” senior author Julia Merrill explained on Eurekalert. Just over 40% of those rationales for not liking the music just had to do with the music itself, but 85% involved the music combined with one of the other categories.

Social reasoning played a big part in dislike. If the listener didn’t feel like a part of the target in-group for the music or the music didn’t have the same social values as those of the listener, it had an impact on dislike, they said.

But our dislike of certain types of music doesn’t just separate us from people in a negative way. Looking at the dislike of certain types of music helps us define our terms of having good taste, the researchers explained. Saying that one type of music is better than another can bring us closer with like-minded people and becomes a piece of how we identify ourselves. Cue the music snobs.

So if you can blast Barry Manilow but can’t bring yourself to play the Rolling Stones, there’s a reason for that. And if you love Aretha Franklin but not Frank Sinatra, there’s a reason for that, too. It’s all very personal. Just as music is meant to be.

Big Vegetable has lied to us all

Hear this, children of the world: Your parents have betrayed you. They tell you day in and day out that vegetables are necessary, that they’re healthy, that you need them, but it is not the truth. Behind their foul taste is nothing but empty lies.

Okay, before we get a full-blown child rebellion on our hands, let’s reel things in. Eating vegetables has many benefits, and will help prevent many nasty medical conditions, such as diabetes or cancer. However, cardiovascular disease is not among them.

For their study published in Frontiers in Nutrition, researchers analyzed the diet, lifestyle, and medical history of nearly 400,000 U.K. adults over a 5-year period, finding that 4.5% developed heart disease and that the average adult consumed about 5 tablespoons of vegetables per day. Those who consumed the most vegetables had a reduction in heart disease incidence of about 15%, compared with those who ate the least.

Hang on, you’re thinking, we just said that vegetables didn’t prevent cardiovascular disease. But the data show otherwise! Ah, but the data are unadjusted. Once the researchers took socioeconomic status, information level, and general lifestyle into account, that benefit disappeared almost completely. The benefit seems to come not from the vegetables themselves, but from being able to afford better food and medical care in general.

The researchers were quick to note the other benefits of eating vegetables, and that people should probably keep eating those five servings a day. But we’re onto you, scientists. You can’t fool us with your vegetable-based lies. Unless we’re talking about pizza. Pizza is the best vegetable.

Renowned infectious disease specialist, humanitarian, and healthcare champion for many of the world’s most vulnerable patient populations, Paul Edward Farmer, MD, died suddenly in his sleep from an acute cardiac event on Feb. 21 in Rwanda, where he had been teaching. He was 62.

Dr. Farmer cofounded the Boston-based global nonprofit Partners In Health and spent decades providing healthcare to impoverished communities worldwide, fighting on the frontline to protect underserved communities against deadly pandemics.

Dr. Farmer was the Kolokotrones University Professor and chair of the department of global health and social medicine in the Blavatnik Institute at Harvard Medical School, Boston. He served as chief of the division of global health equity at Brigham and Women’s Hospital, also in Boston. 

“Paul dedicated his life to improving human health and advocating for health equity and social justice on a global scale,” said HMS dean George Q. Daley in a letter to the HMS community. “I am particularly shaken by his passing because he was not only a consummate colleague and a beloved mentor, but a close friend. To me, Paul represented the heart and soul of Harvard Medical School.”

He was also chancellor and cofounder of the University of Global Health Equity in Kigali, Rwanda. Before his death, he spent several weeks teaching at the university.

“Paul Farmer’s loss is devastating, but his vision for the world will live on through Partners In Health,” said Partners In Health CEO Sheila Davis in a statement. “Paul taught all those around him the power of accompaniment, love for one another, and solidarity. Our deepest sympathies are with his family.”

Dr. Farmer was born in North Adams, Mass., and grew up in Florida with his parents and five siblings. He attended Duke University on a Benjamin N. Duke Scholarship and received his medical degree in 1988, followed by his PhD in 1990 from Harvard University.

His humanitarian work began when he was a college student volunteering in Haiti in 1983 working with dispossessed farmers. In 1987, he cofounded Partners In Health with the goal of helping patients in poverty-stricken corners of the world.

Under Dr. Farmer’s leadership, the nonprofit tackled major public health crises: Haiti’s devastating 2010 earthquake, drug-resistant tuberculosis in Peru and other countries, and an Ebola outbreak that tore through West Africa.

Dr. Farmer documented his 2014-2015 experience treating Africa’s Ebola patients in a book called “Fevers, Feuds, and Diamonds: Ebola and the Ravages of History.”

He wrote that by the time he arrived, “western Sierra Leone was ground zero of the epidemic, and Upper West Africa was just about the worst place in the world to be critically ill or injured.”

One of his greatest qualities was his ability to connect with patients – to treat them “not like ones who suffered, but like a pal you’d joke with,” said Pardis Sabeti, MD, PhD, a Harvard University geneticist who also spent time in Africa and famously sequenced samples of the Ebola virus’ genome.

Dr. Sabeti and Dr. Farmer bonded over their love for Sierra Leone, and their grief over losing a close colleague to Ebola, Sheik Humarr Khan, who was one of the area’s leading infectious disease experts.

Dr. Sabeti first met Dr. Farmer years earlier as a first-year Harvard medical student when she enrolled in one of his courses. She said students introduced themselves, one by one, each veering into heartfelt testimonies about what Dr. Farmer’s work had meant to them.

Dr. Farmer and Dr. Sabeti were just texting on Feb. 19, and the two were “goofing around in our usual way, and scheming about how to make the world better, as we always did.”

Dr. Farmer was funny, mischievous, and above all, exactly what you would expect upon meeting him, Dr. Sabeti said.

“It’s cliché, but the energetic kick you get from just being in his presence, it’s almost otherworldly,” she said. “It’s not even otherworldly in the sense of: ‘I just came across – greatness.’ It’s more: ‘I just came across kindness.’ ”

Dr. Farmer’s work has been widely distributed in publications including Bulletin of the World Health Organization, The Lancet, the New England Journal of Medicine, Clinical Infectious Diseases, and Social Science & Medicine.

He was awarded the 2020 Berggruen Prize for Philosophy & Culture, the Margaret Mead Award from the American Anthropological Association, the American Medical Association’s Outstanding International Physician (Nathan Davis) Award, and, with his Partners In Health colleagues, the Hilton Humanitarian Prize.

He is survived by his wife, Didi Bertrand Farmer, and their three children.

The Omicron decline continued for a fourth consecutive week as new cases of COVID-19 in children fell by 42% from the week before, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

That 42% represents a drop from the 299,000 new cases reported for Feb. 4-10 down to 174,000 for the most recent week, Feb. 11-17. In the last 4 weeks, the United States has seen new child cases drop 85% from a pandemic-high 1.15 million in mid-January, the AAP and CHA said in their weekly COVID-19 report.

The overall count of COVID-19 cases in children is 12.5 million over the course of the pandemic, and that represents 19% of cases reported among all ages, the AAP and CHA said based on data collected from 49 states (excluding New York), the District of Columbia, New York City, Puerto Rico, and Guam.

Hospital admissions also continued to fall, with the rate for children aged 0-17 at 0.43 per 100,000 population as of Feb. 20, down by almost 66% from the peak of 1.25 per 100,000 reached on Jan. 16, the Centers for Disease Control and Prevention reported.

A snapshot of the hospitalization situation shows that 1,687 children were occupying inpatient beds on Feb. 16, compared with 4,070 on Jan. 19, which appears to be the peak of the Omicron surge, according to data from the Department of Health & Human Services.

The state with the highest rate – 5.6 per 100,000 children – on Feb. 16 was North Dakota, although the District of Columbia came in at 11.0 per 100,000. They were followed by Oklahoma (5.3), Missouri (5.2), and West Virginia (4.1). There were three states – New Hampshire, Rhode Island, and Utah – with no children in the hospital on that date, the HHS said.

New vaccinations in children aged 5-11 years, which declined in mid- and late January, even as Omicron surged, continued to decline, as did vaccine completions. Vaccinations also fell among children aged 12-17 for the latest reporting week, Feb. 10-16, the AAP said in a separate report.

As more states and school districts drop mask mandates, data from the CDC indicate that 32.5% of 5- to 11-year olds and 67.4% of 12- to 17-year-olds have gotten at least one dose of the COVID-19 vaccine and that 25.1% and 57.3%, respectively, are fully vaccinated. Meanwhile, 20.5% of those fully vaccinated 12- to 17-year-olds have gotten a booster dose, the CDC said.

That 42% represents a drop from the 299,000 new cases reported for Feb. 4-10 down to 174,000 for the most recent week, Feb. 11-17. In the last 4 weeks, the United States has seen new child cases drop 85% from a pandemic-high 1.15 million in mid-January, the AAP and CHA said in their weekly COVID-19 report.

The overall count of COVID-19 cases in children is 12.5 million over the course of the pandemic, and that represents 19% of cases reported among all ages, the AAP and CHA said based on data collected from 49 states (excluding New York), the District of Columbia, New York City, Puerto Rico, and Guam.

Hospital admissions also continued to fall, with the rate for children aged 0-17 at 0.43 per 100,000 population as of Feb. 20, down by almost 66% from the peak of 1.25 per 100,000 reached on Jan. 16, the Centers for Disease Control and Prevention reported.

A snapshot of the hospitalization situation shows that 1,687 children were occupying inpatient beds on Feb. 16, compared with 4,070 on Jan. 19, which appears to be the peak of the Omicron surge, according to data from the Department of Health & Human Services.

The state with the highest rate – 5.6 per 100,000 children – on Feb. 16 was North Dakota, although the District of Columbia came in at 11.0 per 100,000. They were followed by Oklahoma (5.3), Missouri (5.2), and West Virginia (4.1). There were three states – New Hampshire, Rhode Island, and Utah – with no children in the hospital on that date, the HHS said.

New vaccinations in children aged 5-11 years, which declined in mid- and late January, even as Omicron surged, continued to decline, as did vaccine completions. Vaccinations also fell among children aged 12-17 for the latest reporting week, Feb. 10-16, the AAP said in a separate report.

As more states and school districts drop mask mandates, data from the CDC indicate that 32.5% of 5- to 11-year olds and 67.4% of 12- to 17-year-olds have gotten at least one dose of the COVID-19 vaccine and that 25.1% and 57.3%, respectively, are fully vaccinated. Meanwhile, 20.5% of those fully vaccinated 12- to 17-year-olds have gotten a booster dose, the CDC said.

The Omicron subvariant, BA.2, is not only more transmissible than the original Omicron strain, BA.1, but may cause more severe disease, a lab study from Japan says.

“Our multiscale investigations suggest that the risk of BA.2 for global health is potentially higher than that of BA.1,” the researchers said in the study published on the preprint server bioRxiv. The study has not been peer-reviewed.

The researchers infected hamsters with BA.1 and BA.2. The hamsters infected with BA.2 got sicker, with more lung damage and loss of body weight. Results were similar when mice were infected with BA.1 and BA.2.

“Infection experiments using hamsters show that BA.2 is more pathogenic than BA.1,” the study said.

BA.1 and BA.2 both appear to evade immunity created by COVID-19 vaccines, the study said. But a booster shot makes illness after infection 74% less likely, CNN said.

What’s more, therapeutic monoclonal antibodies used to treat people infected with COVID didn’t have much effect on BA.2. 

BA.2 was “almost completely resistant” to casirivimab and imdevimab and was 35 times more resistant to sotrovimab, compared to the original B.1.1 virus, the researchers wrote. 

“In summary, our data suggest the possibility that BA.2 would be the most concerned variant to global health,” the researchers wrote. “Currently, both BA.2 and BA.1 are recognised together as Omicron and these are almost undistinguishable. Based on our findings, we propose that BA.2 should be recognised as a unique variant of concern, and this SARS-CoV-2 variant should be monitored in depth.”

If the World Health Organization recognized BA.2 as a “unique variant of concern,” it would be given its own Greek letter.

But some scientists noted that findings in the lab don’t always reflect what’s happening in the real world of people.

“I think it’s always hard to translate differences in animal and cell culture models to what’s going on with regards to human disease,” Jeremy Kamil, PhD, an associate professor of microbiology and immunology at Louisiana State University Health Shreveport, told Newsweek. “That said, the differences do look real.”

“It might be, from a human’s perspective, a worse virus than BA.1 and might be able to transmit better and cause worse disease,” Daniel Rhoads, MD, section head of microbiology at the Cleveland Clinic in Ohio, told CNN. He reviewed the Japanese study but was not involved in it.

Another scientist who reviewed the study but was not involved in the research noted that human immune systems are evolving along with the COVID variants. 

“One of the caveats that we have to think about, as we get new variants that might seem more dangerous, is the fact that there’s two sides to the story,” Deborah Fuller, PhD, a virologist at the University of Washington School of Medicine, told CNN. “Our immune system is evolving as well. And so that’s pushing back on things.”

Scientists have already established that BA.2 is more transmissible than BA.1. The Omicron subvariant has been detected in 74 countries and 47 U.S. states, according to CNN. About 4% of Americans with COVID were infected with BA.2, the outlet reported, citing the CDC, but it’s now the dominant strain in other nations.

It’s not clear yet if BA.2 causes more severe illness in people. While BA.2 spreads faster than BA.1, there’s no evidence the subvariant makes people any sicker, an official with the World Health Organization said, according to CNBC.

Health authorities in Malawi have declared an outbreak of wild poliovirus type 1 after a case was confirmed in a 3-year-old girl in the capital, Lilongwe. It was the first case in Africa in 5 years, according to the World Health Organization.

Globally, there were only five cases of wild poliovirus in 2021, the WHO states.

“As long as wild polio exists anywhere in the world all countries remain at risk of importation of the virus,” Matshidiso Moeti, MBBS, WHO regional director for Africa, said in the statement.
 

Girl paralyzed in November

The Global Polio Eradication Initiative (GPEI) said in a statement that the 3-year-old girl  experienced paralysis in November, and stool specimens were collected. Sequencing of the virus was conducted in February, 2022, by the National Institute for Communicable Diseases in South Africa, and the Centers for Disease Control and Prevention confirmed the case as WPV1.

According to the WHO announcement, laboratory analysis shows that the strain identified in Malawi is linked to one circulating in Sindh Province in Pakistan. Polio remains endemic only in Afghanistan and Pakistan.

Kacey C. Ernst, PhD, MPH, professor and infectious disease epidemiologist at the University of Arizona’s Zuckerman College of Public Health in Tucson, pointed out that what is not clear from the press release is whether the girl had traveled to Pakistan or was infected in Malawi.

“This is a very significant detail that would indicate whether or not transmission was actively occurring in Malawi. Until that information is released, it is hard to judge the extent of the possible outbreak,” she said in an interview. “The good news is that this case was in fact detected. The surveillance systems are in place and they were able to identify wild-type cases.”

Dr. Ernst said that although there is cause for concern, it is “not a reason to panic. Malawi has very high polio vaccination rates and it is quite possible that this will be a very small defined outbreak that will be well contained.”

She added that the medical community should be alerted that this case has been identified so travelers who have been to affected areas who have any symptoms can be appropriately screened.

The WHO said it is helping Malawi health authorities in the response, including increasing immunizations.

However, a vaccination campaign comes at a time of health system upheaval in Malawi.

“Malawi, like countries all over the world, has seen an interruption in services due to COVID,” Joia S. Mukherjee, MD, MPH, chief medical officer with Partners in Health and associate professor with the division of global health equity at Brigham and Women’s Hospital and in the department of global health and social medicine at Harvard Medical School, Boston, said in an interview. “In addition, Malawi is currently dealing with the aftermath of a cyclone – where nearly a million people were displaced. Vaccination campaigns work best if there is solid infrastructure. Both COVID and the impact of climate change have shaken the health system.”

UN health agencies warned last year that millions of children who have not received immunizations during the pandemic, especially in Africa, “are now at risk from life-threatening diseases such as measles, polio, yellow fever, and diphtheria,” Reuters reported.

Africa was certified as wild poliovirus free on Aug. 25, 2020. The CDC had served as the lead partner over 3 decades in helping Africa reach the milestone. Africa will retain that status, the WHO stated, because the strain originated in Pakistan.

Five of six WHO regions have been certified polio free. The Americas received eradication certification in 1994.

There is no cure for polio, which can cause irreversible paralysis within hours, but the disease has been largely eradicated globally with an effective vaccine.
 

GPEI sending teams

The GPEI is sending a team to Malawi to support emergency operations, communications, and surveillance. Partner organizations will also send teams to support operations and innovative vaccination campaign solutions.

GPEI was launched in 1988 with the combined efforts of national governments, WHO, Rotary International, the CDC, and UNICEF. The GPEI partnership has included the Bill & Melinda Gates Foundation and, in recent years, Gavi, the Vaccine Alliance.

The CDC states, “[G]lobal incidence of polio has decreased by 99.9% since GPEI’s foundation. An estimated 16 million people today are walking who would otherwise have been paralyzed by the disease, and more than 1.5 million people are alive, whose lives would otherwise have been lost. Now the task remains to tackle polio in its last few strongholds and get rid of the final 0.1% of polio cases.”
 

Three wild poliovirus strains

There are three wild poliovirus strains: type 1 (WPV1), type 2 (WPV2), and type 3 (WPV3).

“Symptomatically, all three strains are identical, in that they cause irreversible paralysis or even death. But there are genetic and virologic differences which make these three strains three separate viruses that must each be eradicated individually,” according to WHO.

WPV3 is the second strain to be wiped out, following the certification of the eradication of WPV2 in 2015.

Two features are significantly associated with a higher risk for developing long COVID symptoms among people with inflammatory bowel disease (IBD), according to a large Danish population study.

People with Crohn’s disease (CD) who experienced adverse acute COVID-19, defined as requiring hospitalization, were nearly three times more likely to report persistent symptoms 12 weeks after acute infection.

“Long-term, persisting symptoms following COVID-19 is a frequently occurring problem, which is probably underappreciated. IBD specialists should therefore be aware of any of these symptoms and actively ask patients whether they have these problems,” lead author Mohamed Attauabi, MD, PhD, said in an interview.

Dr. Attauabi and colleagues also found that people with ulcerative colitis (UC) who discontinued immunosuppressive agents because of COVID-19 were 1.5 times more likely to experience long COVID symptoms, a result that surprised the researchers.

“This has not been shown before and remains to be confirmed,” said Dr. Attauabi, a fellow in the department of gastroenterology at Herlev Hospital at the University of Copenhagen.

Attauabi presented the results as a digital oral presentation at the 17th congress of the European Crohn’s and Colitis Organisation.
 

A closer look at IBD and COVID-19

Large, hospital-based studies of symptoms consistent with long COVID reveal a high prevalence of fatigue, sleep difficulties, and anxiety at 12 weeks or more post acute infection. However, these were not specific to people with CD or UC, Dr. Attauabi said.

“In patients with IBD, the risk of long-term sequelae of COVID-19 remains to be investigated,” he said.

Dr. Attauabi and colleagues studied 197 people with CD and 319 with UC, all of whom had polymerase chain reaction–confirmed COVID-19. Participants were prospectively enrolled in the population-based Danish IBD-COVID registry from January 28, 2020 to April 1, 2021. At a median of 5.1 months, a subset of 85 people with CD and 137 with UC agreed to report any post-COVID symptoms.

Older age, smoking, IBD disease activity, and presence of comorbidities were not associated with a significantly elevated risk of long COVID.

In a multivariate analysis, hospitalization for COVID-19 among people with CD was significantly associated with long COVID (odds ratio, 2.76; 95% confidence interval, 1.05-3.90; P = .04).

Furthermore, people with UC who stopped taking immunosuppressive agents also had a significantly higher risk (OR, 1.50; 95% CI, 1.07-10.22; P = .01).

“However, IBD medications such as systemic steroids were not associated with this outcome,” Dr. Attauabi said.
 

Fatigue most common long COVID symptom

Fatigue was the most common long COVID symptom, reported by 37% of patients with CD and 36% with UC.

Anosmia and ageusia were also common, reported by 29% and 28% of patients with CD, and 27% and 19% of those with UC, respectively.

“In our cohort of patients with UC or CD who developed COVID-19, the long-term health effects of COVID-19 did not appear to differ among patients with UC or CD nor according to IBD medications,” Dr. Attauabi said.

That is a “great study,” said session cochair Torsten Kucharzik, MD, PhD, head of internal medicine and gastroenterology at Lueneburg (Germany) Hospital.

When Dr. Kucharzik asked about smoking, Dr. Attauabi responded that they collected information on current and previous smoking, but they chose not to include the data because it was not statistically significant.

Dr. Attauabi has reported no relevant financial relationships. Dr. Kucharzik has reported receiving grants from Takeda and personal fees from companies including MSD/Essex, AbbVie, Falk Foundation, Biogen, Bristol-Myers Squibb, Arena, Celgene, Celltrion, Ferring, Janssen, Galapagos, Olympus, Mundipharma, Takeda, Amgen, Pfizer, Roche, and Vifor Pharma.

In a multivariate analysis, hospitalization for COVID-19 among people with CD was significantly associated with long COVID (odds ratio, 2.76; 95% confidence interval, 1.05-3.90; P = .04).

Furthermore, people with UC who stopped taking immunosuppressive agents also had a significantly higher risk (OR, 1.50; 95% CI, 1.07-10.22; P = .01).

“However, IBD medications such as systemic steroids were not associated with this outcome,” Dr. Attauabi said.
 

Fatigue most common long COVID symptom

Fatigue was the most common long COVID symptom, reported by 37% of patients with CD and 36% with UC.

Anosmia and ageusia were also common, reported by 29% and 28% of patients with CD, and 27% and 19% of those with UC, respectively.

“In our cohort of patients with UC or CD who developed COVID-19, the long-term health effects of COVID-19 did not appear to differ among patients with UC or CD nor according to IBD medications,” Dr. Attauabi said.

That is a “great study,” said session cochair Torsten Kucharzik, MD, PhD, head of internal medicine and gastroenterology at Lueneburg (Germany) Hospital.

When Dr. Kucharzik asked about smoking, Dr. Attauabi responded that they collected information on current and previous smoking, but they chose not to include the data because it was not statistically significant.

Dr. Attauabi has reported no relevant financial relationships. Dr. Kucharzik has reported receiving grants from Takeda and personal fees from companies including MSD/Essex, AbbVie, Falk Foundation, Biogen, Bristol-Myers Squibb, Arena, Celgene, Celltrion, Ferring, Janssen, Galapagos, Olympus, Mundipharma, Takeda, Amgen, Pfizer, Roche, and Vifor Pharma.

Two features are significantly associated with a higher risk for developing long COVID symptoms among people with inflammatory bowel disease (IBD), according to a large Danish population study.

People with Crohn’s disease (CD) who experienced adverse acute COVID-19, defined as requiring hospitalization, were nearly three times more likely to report persistent symptoms 12 weeks after acute infection.

“Long-term, persisting symptoms following COVID-19 is a frequently occurring problem, which is probably underappreciated. IBD specialists should therefore be aware of any of these symptoms and actively ask patients whether they have these problems,” lead author Mohamed Attauabi, MD, PhD, said in an interview.

Dr. Attauabi and colleagues also found that people with ulcerative colitis (UC) who discontinued immunosuppressive agents because of COVID-19 were 1.5 times more likely to experience long COVID symptoms, a result that surprised the researchers.

“This has not been shown before and remains to be confirmed,” said Dr. Attauabi, a fellow in the department of gastroenterology at Herlev Hospital at the University of Copenhagen.

Attauabi presented the results as a digital oral presentation at the 17th congress of the European Crohn’s and Colitis Organisation.
 

A closer look at IBD and COVID-19

Large, hospital-based studies of symptoms consistent with long COVID reveal a high prevalence of fatigue, sleep difficulties, and anxiety at 12 weeks or more post acute infection. However, these were not specific to people with CD or UC, Dr. Attauabi said.

“In patients with IBD, the risk of long-term sequelae of COVID-19 remains to be investigated,” he said.

Dr. Attauabi and colleagues studied 197 people with CD and 319 with UC, all of whom had polymerase chain reaction–confirmed COVID-19. Participants were prospectively enrolled in the population-based Danish IBD-COVID registry from January 28, 2020 to April 1, 2021. At a median of 5.1 months, a subset of 85 people with CD and 137 with UC agreed to report any post-COVID symptoms.

Older age, smoking, IBD disease activity, and presence of comorbidities were not associated with a significantly elevated risk of long COVID.

In a multivariate analysis, hospitalization for COVID-19 among people with CD was significantly associated with long COVID (odds ratio, 2.76; 95% confidence interval, 1.05-3.90; P = .04).

Ivermectin treatment given to high-risk patients with mild-to-moderate COVID-19 during the first week of illness did not prevent progression to severe disease, according to results from a randomized clinical trial.

“The study findings do not support the use of ivermectin for patients with COVID-19,” researchers conclude in the paper published online in JAMA Internal Medicine.

The open-label trial was conducted at 20 public hospitals and a COVID-19 quarantine center in Malaysia between May 31 and Oct. 25, 2021. It was led by Steven Chee Loon Lim, MRCP, department of medicine, Raja Permaisuri Bainun Hospital, Perak, Malaysia.

Among 490 patients in the primary analysis, 52 of 241 patients (21.6%) in the ivermectin group and 43 of 249 patients (17.3%) in the control group progressed to severe disease (relative risk, 1.25; 95% confidence interval, 0.87-1.80; P = .25). All major ethnic groups in Malaysia were well represented, the researchers write.

Participants (average age 62.5 and 54.5% women) were randomly assigned 1:1 to receive either a 5-day course of oral ivermectin (0.4 mg/kg body weight daily for 5 days) plus standard of care (n = 241) or standard of care alone (n = 249). Standard of care included symptomatic therapy and monitoring for early deterioration based on clinical findings, laboratory tests, and chest imaging.
 

Secondary outcomes

Secondary outcomes included rates of mechanical ventilation, intensive care unit (ICU) admission, 28-day in-hospital mortality, and side effects.

In all the secondary outcomes, there were no significant differences between groups.

Mechanical ventilation occurred in four patients on the ivermectin protocol (1.7%) versus 10 patients in the control group (4.0%) (RR, 0.41; 95% CI, 0.13-1.30; P = .17); ICU admission occurred in six (2.4%) versus eight (3.2%) (RR, 0.78; 95% CI, 0.27-2.20; P = .79); and 28-day in-hospital death occurred in three (1.2%) versus 10 (4.0%) (RR, 0.31; 95% CI, 0.09-1.11; P = .09).

The most common adverse event was diarrhea, reported by 5.8% in the ivermectin group and 1.6% in the control group.
 

No difference by vaccine status

The researchers conducted a subgroup analysis to evaluate any differences in whether participants were vaccinated. They said that analysis was “unremarkable.”

Just more than half of participants (51.8%) were fully vaccinated, with two doses of COVID-19 vaccines. Among the fully vaccinated patients, 17.7% in the ivermectin group and 9.2% in the control group developed severe disease (RR, 1.92; 95% CI, 0.99-3.71; P = .06).

Ivermectin, an inexpensive and widely available antiparasitic drug, is prescribed to treat COVID-19 but has not been approved by the U.S. Food and Drug Administration for that purpose. Evidence-based data for or against use has been sparse.

The authors write that “although some early clinical studies suggested the potential efficacy of ivermectin in the treatment and prevention of COVID-19, these studies had methodologic weaknesses.”

Dr. Lim and colleagues point out that their findings are consistent with those of the IVERCOR-COVID19 trial, which found ivermectin ineffective in reducing hospitalization risk.

Previous randomized trials of ivermectin for COVID-19 patients that have included at least 400 patients have focused on outpatients.

In the current study, the authors note, patients were hospitalized, which allowed investigators to observe administration of ivermectin with a high adherence rate. Additionally, the researchers used clearly defined criteria for determining progression to severe disease.

Limitations of the current study include that the open-label design might lead to under-reporting of adverse events in the control group while overestimating the drug effects of ivermectin. The study was also not designed to assess the effects of ivermectin on mortality from COVID-19.
