Do the Omicron numbers mean what we think they mean?

Do the Omicron numbers mean what we think they mean?

Dhruv Khullar writes: More than a hundred and fifty thousand Americans are currently hospitalized with the coronavirus—a higher number than at any other point in the pandemic. But that figure, too, is not quite what it seems. Many hospitalized Covid patients have no respiratory symptoms; they were admitted for other reasons—a heart attack, a broken hip, cancer surgery—and happened to test positive for the virus. There are no nationwide estimates of the proportion of hospitalized patients with “incidental covid,” but…

Two decades of soldiers’ medical records implicate common virus in multiple sclerosis

Two decades of soldiers’ medical records implicate common virus in multiple sclerosis

Science reports: One hundred and fifty years after a French neurologist first recognized a case of multiple sclerosis (MS) in a young woman with an unusual tremor, the cause of this devastating disease remains elusive. Now, a study that combed data from regular blood tests of 10 million U.S. soldiers has found the strongest evidence yet that infection with a common virus, Epstein-Barr virus (EBV), dramatically increases a person’s chances of developing the rare disease. The work leaves many questions,…

Can weed protect you from Covid?

Can weed protect you from Covid?

Slate reports: Fikadu Tafesse wasn’t expecting to wake up on Wednesday to a text in which his former mentor blamed him for his children’s new interest in weed. Earlier this week, Tafesse, a professor of molecular microbiology and immunology at Oregon Health & Science University, published evidence that some compounds found in cannabis plants could prevent the coronavirus from infecting cells. The internet latched onto the idea that weed might protect them from COVID: Twitter users made memes about the…

How is the pandemic affecting the brains of a generation of children?

How is the pandemic affecting the brains of a generation of children?

Nature reports: Like many paediatricians, Dani Dumitriu braced herself for the impact of the SARS-CoV-2 coronavirus when it first surged in her wards. She was relieved when most newborn babies at her hospital who had been exposed to COVID-19 seemed to do just fine. Knowledge of the effects of Zika and other viruses that can cause birth defects meant that doctors were looking out for problems. But hints of a more subtle and insidious trend followed close behind. Dumitriu and…

The world we want to live in after Covid

The world we want to live in after Covid

Dhruv Khullar writes: In 1909, the French ethnographer Arnold van Gennep published a book called “The Rites of Passage.” In it, he explored the rituals that cultures use to transition people from one stage of life to the next. Birth, puberty, graduation, religious initiation, marriage, pregnancy, promotions, the seasons—we’re always on the threshold of one phase or another. How do communities shepherd individuals from the pre- to the post-? Van Gennep argued that certain universal principles underlie rites of passage…

Evolution ‘landscapes’ predict what’s next for Covid virus

Evolution ‘landscapes’ predict what’s next for Covid virus

Carrie Arnold writes: In the fall of 2019, the world began one of the largest evolutionary biology experiments in modern history. Somewhere near the city of Wuhan in eastern China, a coronavirus acquired the ability to live inside humans rather than the bats and other mammals that had been its hosts. It adapted further to become efficient at spreading from one person to the next, even before the body’s defenses could rise against it. But the evolutionary chess game didn’t…

The forgotten medieval habit of ‘two sleeps’

The forgotten medieval habit of ‘two sleeps’

Zaria Gorvett writes: In the 17th Century, a night of sleep went something like this. From as early as 21:00 to 23:00, those fortunate enough to afford them would begin flopping onto mattresses stuffed with straw or rags – alternatively it might have contained feathers, if they were wealthy – ready to sleep for a couple of hours. (At the bottom of the social ladder, people would have to make do with nestling down on a scattering of heather or,…

Global spread of autoimmune disease blamed on Western diet

Global spread of autoimmune disease blamed on Western diet

The Guardian reports: More and more people around the world are suffering because their immune systems can no longer tell the difference between healthy cells and invading micro-organisms. Disease defences that once protected them are instead attacking their tissue and organs. Major international research efforts are being made to fight this trend – including an initiative at London’s Francis Crick Institute, where two world experts, James Lee and Carola Vinuesa, have set up separate research groups to help pinpoint the…

Omicron isn’t mild for the health-care system

Omicron isn’t mild for the health-care system

Ed Yong writes: When a health-care system crumbles, this is what it looks like. Much of what’s wrong happens invisibly. At first, there’s just a lot of waiting. Emergency rooms get so full that “you’ll wait hours and hours, and you may not be able to get surgery when you need it,” Megan Ranney, an emergency physician in Rhode Island, told me. When patients are seen, they might not get the tests they need, because technicians or necessary chemicals are…

‘Flurona’ is a great example of how misinformation blooms

‘Flurona’ is a great example of how misinformation blooms

Raghu Adiga writes: Earlier this week, Israeli media reported a person who was hospitalized with evidence of both seasonal flu and COVID at the same time. This unvaccinated and pregnant person had mild symptoms and was discharged without any complications. A person being infected with both the COVID-causing SARS-CoV2 virus and an influenza virus can happen; we just had one such person in our hospital last month whom we treated and discharged without a whole lot of fanfare. However, the…

Here’s the real deal on flurona

Here’s the real deal on flurona

Jaime Green writes: Two years of pandemic have us primed to panic at every headline. A new variant, a new complication, a new baffling policy move. Now, headlines have brought an alarmingly exotic new word to stoke our fears: flurona. On Sunday the Times of Israel published an article with the headline, “‘Flurona’: Israel Records Its First Case of Patient With COVID and Flu at Same Time.” The first wave of follow-up aggregation articles in other outlets was staid, merely…

The therapeutic value of swearing

The therapeutic value of swearing

Stephen Tuffin writes: When I was a kid, swearing was taboo – except for that one time when my dad, a hulking great navvy of a man, took me down the yard where they kept all the equipment road workers used out on the roads, and I witnessed the cutting down of a tree. An elm, I am reliably told. At home, that evening, sat on the kitchen table of our council house, my mum scrubbing my hands and face,…

One woman’s six-word mantra that has helped to calm millions

One woman’s six-word mantra that has helped to calm millions

Judith Hoare writes: [Dr Claire] Weekes distilled her understanding of ‘nervous illness’ into a six-word mantra for overcoming anxiety: face, accept, float, let time pass. In Self-Help for Your Nerves, she said that sufferers usually spent their time counterproductively: Running away, not facing. Fighting, not accepting. Arresting and ‘listening in’, not floating past. Being impatient with time, not letting time pass. The nervously ill person usually notices each new symptom in alarm, listens-in in apprehension, and yet at the same…

For the past two years, Americans have accepted more harm to children in exchange for less harm to adults

For the past two years, Americans have accepted more harm to children in exchange for less harm to adults

David Leonhardt writes: Children fell far behind in school during the first year of the pandemic and have not caught up. Among third through eighth graders, math and reading levels were all lower than normal this fall, according to NWEA, a research group. The shortfalls were largest for Black and Hispanic students, as well as students in schools with high poverty rates. “We haven’t seen this kind of academic achievement crisis in living memory,” Michael Petrilli of the Thomas B….

Omicron doesn’t infect the lungs very well, animal studies find

The New York Times reports: A spate of new studies on lab animals and human tissues are providing the first indication of why the Omicron variant causes milder disease than previous versions of the coronavirus. In studies on mice and hamsters, Omicron produced less damaging infections, often limited largely to the upper airway: the nose, throat and windpipe. The variant did much less harm to the lungs, where previous variants would often cause scarring and serious breathing difficulty. “It’s fair…

Beyond case counts: What Omicron is teaching us

Beyond case counts: What Omicron is teaching us

STAT reports: The Omicron wave in the United States is upon us. If you were fortunate enough to tune out from Covid-19 news over the holidays, you’re coming back to startling reports about record high case counts and, in some places, increases in hospitalizations. The wave will crest, of course; the question is when. For now, experts say, the country still has a ways to go to get through the Omicron surge. Below, STAT outlines what Omicron is already teaching…
