How long does an infected person shed virus?
It’s not known how long you actually shed the virus at the moment, but what is known is that your tests stay positive, in most people, for about three weeks. So once you’ve got the infection, your throat swab stays positive for about three weeks. And you’d have to assume that you’re shedding the virus, and therefore infectious during that time. So it’s quite a long time.
