Doctors who treat Covid describe the ways the illness has gotten milder and shifted over time to mostly affect the upper respiratory tract.
Doctors say they’re finding it increasingly difficult to distinguish Covid from allergies or the common cold, even as hospitalizations tick up.
The illness’ past hallmarks, such as a dry cough or the loss of sense of taste or smell, have become less common. Instead, doctors are observing milder disease, mostly concentrated in the upper respiratory tract.
“It isn’t the same typical symptoms that we were seeing before. It’s a lot of congestion, sometimes sneezing, usually a mild sore throat,” said Dr. Erick Eiting, vice chair of operations for emergency medicine at Mount Sinai Downtown in New York City.
The sore throat usually arrives first, he said, then congestion.
As a person who is on the tail end of COVID infection, this describes my current symptoms.
Do the old covid tests still work? Ive had this cold several times this year and always covid negative.
They have a much higher false negative rate now than they used to. Thats probably due to changes in the virus itself and lower viral load as people have higher levels of immunity now. However if you test positive you can still be pretty certain you have covid.
Yes, also recognition that some people may have symptoms and test negative or feel fine and test positive. That’s also why there is no recommendation to test again. If someone pops a positive recommendations say to stay home for 5 days then mask for 5 more. There is no benefit to additional testing because of natural variation in antibody production and function.
I simply had the worst sore throat I’ve ever had. No congestion. Then I lost my sense of smell for about 6 months. That was awful. Very grateful it came back.
So is there any real way to say if this is because of widespread vaccination or because the virus itself has lost some lethality genes
Not a scientist, but I’d guess mostly B, maybe helped along with some of A.
The goal of a virus is to replicate, and it does that better when it’s less lethal
Just a very small correction- as with all biology, natural selection will drive a virus to replicate more effectively, that’s it. This does NOT mean a virus will automatically become less lethal over time. That’s an older hypothesis that scientists found was not in line with observation.
The newer hypothesis is known as “virulence-transmission trade-off”. The oversimplification of the idea is that if a mutation increases both transmission and virulence, it will also tend to be selected for. COVID is inconsistent with both hypotheses in certain ways though, so really predicting its virulence in the short or long term has proven difficult.

The old idea isn’t wrong per se, lower lethality is a good survival trait. It just has to be weighed against the value of transmission, which would intuitively have a much higher value. In covid, the lethality rate is even less inpactful because it is contagious for a relatively long period before the host would suffer severe illness. But low lethality is still a good thing, and in such a widespread disease one would still expect that trait to become more pronounced eventually. That doesn’t mean it necessarily would, statistically likely doesn’t mean certain, especially if a particular mutation gave it a substantial bump to both traits it may never be selected out for example. But the current trend seems to be a result of this likelihood.
Viruses don’t have goals. You are anthropomorphizing them. What viruses do is mutate. If mutations have more fitness, they will spread more effectively. That says nothing about mortality nor morbidity. With this disease it spreads in the early stage, which long before the person who has caught it either dies, recovers, gets long COVID, etc.
Scheduled next boost for next week.
I finally caught it earlier this year. Thanks to vax, it was similar to a cold / flu. Was mostly better after a few days.
Medical science is awesome. I couldn’t be happier about how it turned out. What a relief.
The EMA recommeded it recently. I think that has to filter down into member states now. So for the EU next week would probably be too soon. For Switzerland it’s not approved yet. But maybe in other non-EU countries somewhere?
