I thought it was at least 2 weeks, to a month. I know that if anyone tests positive for it, they should stay at home, particularly if they're not vaccinated. As far as I know, a relative of mine, a woman friend of my family, and many other acquaintances have had it. My cousin had to be hospitalized a bout a month, the lady family friend almost didnt make it and was sick at least a month, and the rest of acquaintances died. My brother alone knows 5 people who died, all friends at a senior art class he goes to.
It's a serious illness and with the Delta variant growing in cases each day, I would recommend staying at home and having people do things for you as much as possible. Avoid going out.
