More fear mongering... Million's have recovered from COVID completely, and they don't have any lingering effects from it as they rejoin society and their lives.
Infact a negative test means just that "A NEGATIVE RESULT", in which concludes that there is no Covid infection still present in the body, and therefore it's not doing continued harm to the body if it's no longer present in the body.
Now there is the possibility that it might have made the lungs more sensitive to maybe getting viruses easier and such at a later date, but usually that comes from age or having a weakened or compromised immune system that is damaged while the virus was in play.
Doesn't mean that the virus is still present, but it could mean that the system may have been weakened a little, therefore making the body a little more susceptible in the future to such a thing.
Some people get pneumonia almost every year after their system becomes susceptible to it, but that's just life in getting older, and therefore more fragile in life. I know people that have pneumonia pop up here and there, and they are treated for it, and get well. Viruses aren't the end of the road for most, but if one isn't healthy then it best to be aware of that, and take certain measure's to protect oneself. Don't expect those that are healthy to live a compromised live just to make someone else feel good, safe or better about themselves.
We went to events over the summer, and many weren't wearing mask, and other's were. No one was looking at each other as if there was something stupid going on. It was very nice and respectable. No hysteria, no Karen's, and no problem.
