My son had positive tests for over a month and was clearly not ill. In fact, he never really got sick with Covid. This was the first- go around, back in 2020, December. He had to be quarantined in the US Army before he got to go to basic training. So, yeah, that's a thing. Take it easy and pray you will not have symptoms for as long as I did. Mine have lasted for over a year now. And, there were alot of other people there at the event that were sick as well....not just the woman coughing. We are contagious long before we are "sick". That goes for most viruses. This one isn't different. We just must do our best.
