We now have the first confirmed U.S. case of someone getting reinfected with COVID-19.
Scientists published a report about it on Monday, the same day President Donald Trump spoke at a rally in Sanford, where he said that he might be immune.
The case involves a 25-year-old in Nevada. Scientists say they know he was infected two different times because he tested positive in April, then tested negative twice in May before testing positive again in June.
Doctors said reinfection could be rare, and it’s hard to determine, because there’s no comprehensive surveillance system in place to track if someone gets the virus again.
The 25-year-old in the study was sicker the second time around, but eventually recovered.
