5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.

The auto mod will contact you if a link shortener is detected, please delete your post if they are right.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.
As a person who is on the tail end of COVID infection, this describes my current symptoms.
I never tested myself because I just thought it was a cold, but that describes my symptoms too. Started with sore throat which wasn't too bad and went away. Then the next day congestion and exhaustion, with just a little bit of sneezing.
These symptoms lasted nearly a month after my covid infection.
Same for me as well
Do the old covid tests still work? Ive had this cold several times this year and always covid negative.
The answer is yes they are still as effective, dont let anyone here convince you otherwise. The base protein has not mutated and that is what is being checked when you do this chromatography style test.
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.
Mind the expiration dates.
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.

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.
It's not anthropomorphizing, it's abstraction and it's incredibly common in evolutionary science to speak in this manner.
It helps that it already killed millions of the more susceptible early on before immunity started.
Not sure how statistically significant this is in the overall numbers, though.
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.
That was the basic progression when I had it a few months ago if you add fever and chills.
Huh, I have exactly that. Dunno if covid though of just some flu
