Can Long Haulers Get Covid Again
Today we bring you lot a new episode in our podcast serial COVID, Quickly. Every 2 weeks, Scientific American's senior health editors Tanya Lewis and Josh Fischman catch yous up on the essential developments in the pandemic: from vaccines to new variants and everything in between.
You lot can heed to all past episodes hither.
Josh Fischman: Hello, and welcome to COVID, Quickly, a Scientific American podcast series.
This is your fast-track update on the COVID pandemic. We bring you up to speed on the scientific discipline behind the well-nigh urgent questions about the virus and the disease. We demystify the inquiry and help you sympathize what it really ways.
I'm Josh Fischman, Scientific American's senior health editor. Tanya Lewis, unremarkably here with me, has the twenty-four hours off.
Today the giant Omicron moving ridge looks similar it may have peaked in the U.Southward. We'll expect at its unusual furnishings on two groups: children and people with long-haul COVID. And we'll talk about a dramatic worldwide vaccine milestone.
Omicron cases look like they are starting to drop in many U.S. states. Just they're coming downwards from staggering heights. By mid-February, about 40 percent of the U.S. population volition be infected by the variant. That's an approximate from Trevor Bedford of the Fred Hutchinson Cancer Research Center in Seattle, who models infection rates.
And that's changed one important feature of the pandemic: Kids getting sick. With earlier variants, very few children got seriously sick. Merely recently an average of about 800 children have been admitted to the hospital with COVID every day. For kids nether five, the hospitalization rates jumped to 2 to four times that of previous waves.
What's going on? Has the virus mutated to get worse for kids? Probably not, scientists say. What we're seeing is a consequence of the overall vast number of Omicron infections.
There'southward a proverb: a small fraction of a large number is still a big number. And that seems to exist what's going on with kids and COVID. A pocket-size portion of infected kids have always gotten seriously ill. Now we have a lot more infected kids. Almost a million in the first 2 weeks of January solitary. So fifty-fifty if the portion of infections that demand a trip to the hospital stays the aforementioned, the absolute number is going to jump up.
The good news is that Omicron really seems less severe than the earlier variant, Delta. Rong Xu, a data scientist at Case Western Reserve University, looked at health records of 80,000 kids and found the Omicron hospitalization rate was one percent. With Delta information technology was higher, at three percentage. But again, with a lot more than infected kids, that one percent turns into a bigger bodily number.
1 thing about Omicron that may make it harder on kids is where this variant likes to hang out and multiply. Earlier versions of the virus went deep into the lungs. This 1, yet, seems to like the airway above the lungs, including the throat. Kids' airways are tinier, and then its easier for them to become clogged with mucus and inflamed with infection.
That leads to conditions like croup, which includes a wracking, barking cough that alarms parents. Simply again some good news: croup symptoms normally become away in near three days. Ibuprofen tin can reduce the pain and swelling. Steroids help in more serious cases. It'south a familiar illness and doctors know how to care for it. Telephone call one if your child is having trouble breathing.

The other grouping of people that'south probably going to be hit by Omicron'due south huge numbers are long haulers, or people with what's chosen long COVID. After their initial infection, these people struggle for months with a cluster of disabling symptoms. The listing includes deep fatigue, shortness of breath, body pain, and headaches. It tin be incommunicable to work or accept care of your children, difficult to cook and exercise other things that are basic parts of daily life.
Doctors now estimate that 14 to xxx percent of people who get the coronavirus suffer from this syndrome.
And every bit with kids and Omicron, the percent isn't equally important as the actual number. Considering the wildly contagious variant has infected tens of millions of people, if only a pocket-size fraction of those who catch it develop long COVID, millions could be burdened with symptoms for months, if not years.
And simply considering many Omicron cases are mild doesn't mean such people are immune from lingering symptoms. David Putrino, a rehabilitation medicine specialist at the Icahn School of Medicine in New York City, told my colleague Melinda Wenner Moyer that people with mild illness do go on to get long COVID. A study in the U.K found that ongoing health problems were simply weakly linked to severity of illness.
Ane thing that does reduce the frequency of long COVID is vaccination. Some other U.K study showed that if people were fully vaccinated, and got a second, quantum infection, simply 5 percent had symptoms afterward a month. But 11 percent of unvaccinated people did accept serious symptoms.
In the U.Southward. a report found vaccinated people were 7 to ten times less likely to report long COVID problems months after their initial diagnosis than were non-vaccinated people.
So just like with acute COVID, shots help eliminate the run a risk of a long haul.

Beyond the globe, there now have been 10 billion COVID vaccine shots given out, a major milestone this month. In that location are 20 different kinds of vaccines, and 4.8 billion people have received at least one dose. That is 60 pct of the population on our planet. That'southward in only over a twelvemonth, an unprecedented rollout of medicine.
They have not quite been the shots heard around the earth, withal. Most of them have gone to people in richer countries. In poor countries, just 5.5. percentage of people have received a full ii-dose regimen. In the entire continent of Africa, more than 80 per centum of the people have not gotten fifty-fifty one dose, according to a news story in Nature magazine.
Not just does that inequality put people in low-income countries at much higher risk of disease, it too raises the risk of new coronavirus variants evolving in these areas. And equally the past two years have taught us, variants don't stay at domicile.
The way out of the pandemic is amend global distribution. We're getting there–ten billion doses is a big number–but we need to get at that place even faster.
