Apparently there are a lot of them! This article seems to be a very even-handed review of what’s known, being guessed at, and how big the unknowns are around asymptomatic virus related health issues. Asymptomatic COVID is just a new neighborhood on a very large map.

It was my understanding that Covid hasn’t changed that part of its stripes. One would come back from a convention with “con crud” due to the large number of folks who weren’t yet symptomatic but were in the “spreader zone”.

One of the takeaways from this article for me was that there are some folks who can be infected, able to spread, but will never show symptoms during or after their immune system defeats the virus. So, “yet” isn’t in play for them. Whether they are blessed with the right type & quantity of T-cells or some other virus fighting weapons, they can manage to stay symptom free for the entire battle.
I’m sure other folks are better informed about “asymptomatic” than I was. Didn’t seem to register on my radar before C-19 reared its ugly head. I had wondered if it was a DNA thing not unlike those who are essentially unaffected by smoking. This article had a better explanation and referenced the body of research on the topic.

I think this is a big part of where people’s understanding of COVID spread (and other illnesses) fail. The people saying “I feel fine, why should I quarantine?” or “I’m/you’re vaccinated, why should I/you wear a mask?” and this is why.
Even after you’ve recovered from some illnesses you can still spread that illness. I have to stress to people all the time that even though their dog is happy and bouncy again after say, a parvo infection, he can still spread it to others so keep him away from others for another two weeks. They rarely listen.
