A friend who is a serious jock bike rider got the virus recently. On day 5 he felt much better, and after testing negative, could not resist a little bike ride (which would probably have killed me, but like I said, he bikes all the time).
When he got back, he did not feel so good, and tested positive! A couple of days of rest, and he tested negative again. He was careful not to overwork his body for a couple of weeks, and all is well.
I don't know if the tests are faulty, or if it is in fact possible to get your viral load up from exhaustion.
Curious.
