I have a neighbor that continued to test positive for a month after his symptoms subsided. Don't know what kind of test he was taking but he finally tested negative using a different test.

The whole thing is wacky as hell. We took the same approach when my wife got it. She quarantined from the outside world for 10 days but not from me (though we have been married almost 30 years so there was no kissing or sex anyway). I never got sick.
