Jamie Gillan tested COVID-19 postive after a month

Cleveland Browns punter Jamie Gillan was placed on the team's COVID-19 reserve list on Thursday, after testing positive for the virus. The problem is, he tested positive about a month ago.

I spoke to #Browns punter Jamie Gillan, who landed on the Reserve/COVID-19 list today. The Scottish Hammer says he actually had COVID-19 almost a month ago, and tested negative for the virus (and positive for antibodies) on Tuesday … before a positive test yesterday. □□ pic.twitter.com/o8Kqz9PLMv

Before the COVID truthers and conspiracy theorists run wild with this one, I've known more than one person this has happened to. They test positive, recover, test negative, and then all of a sudden they have the virus again.

Sure, there is a possibility that Gillan's particular test is a 'false positive.' This is just another example of how there are so many unknowns about this virus. How can we definitively know for sure that he doesn't still have it, hasn't contracted it a second time, or can't spread it to others? 

This probably won't be the last time this happens either.
