SARS-CoV-2

Long COVID remains an enigma wrapped within a conundrum. Many individuals claim the affliction. But without a consensus on its diagnosis, unraveling its underlying physiologic changes, let alone therapeutic approaches, is a random walk. It's a lot a drunk searching for their keys under a streetlamp because the light is better. Two developments this week may well begin the unwrapping.
Long COVID burdens tens of millions of Americans and the nation's healthcare system, but our response to it has been fragmented and chaotic. We need to address it without delay, with more research and better access to treatment.
The spread of SARS-CoV-2 infections through many mammal species in the wild raises the specter of deer becoming a SARS-CoV-2 reservoir — a permanent home for the virus and a regular source of outbreaks in other animals, including humans.
In order to prepare for the emergence of new SARS-CoV-2 "variants of concern" or other epidemic coronaviruses, researchers are taking a variety of approaches to creating vaccines that will protect against not only known viruses but also against variants that have not yet appeared.
Long COVID will take a toll on the nation's healthcare system for the foreseeable future, but we can reduce new cases by treating acute COVID infections with a commonly prescribed, inexpensive medicine.
The most infectious subvariant of the SARS-CoV-2 virus yet discovered is spreading through the U.S., and experts are predicting a January-February surge of COVID cases. A corollary is that we will also have more cases of long COVID, which is worrisome given new findings that long COVID, like acute infections, can be fatal. The best way to avoid long COVID is not to get infected in the first place.
The activist group GM has attacked gene-edited crops by alleging that they're designed to increase pesticide use. Is there any truth to this allegation? With millions of COVID vaccine doses administered since December 2020, what have we learned about the risks associated with the shots?
A new paper reports that Paxlovid-resistant Covid has been isolated, calling into question the utility of the drug as well as how it should be used. Is this cause for alarm? Not yet, but it could become just that. A look at viral resistance to drugs.
We're learning more every day about the SARS-CoV-2 virus, but it will likely present surprises. The best strategy is still to prevent new infections.
An unexpected delay in the FDA's authorization of COVID shots for children under age 5 could amplify parents' existing concerns about vaccinating their kids. Here's what we know about the situation.
California is poised to empower children as young as 12 to receive COVID vaccines without parental consent. The Golden State is on the wrong path.
Reporters and science communicators commonly point to widespread COVID misinformation to explain why so many people are skeptical of vaccines and other infection-control measures. Bad pandemic takes clearly influence the public, but there's much more to the story.
