Researchers in Hong Kong say they’ve confirmed that a person can be infected with COVID-19 twice.
There have been sporadic accounts on social media sites of people who say they’ve gotten COVID twice. But scientists have been skeptical about that possibility, saying there’s no evidence it happens.
The new proof comes from a 33-year-old man in Hong Kong who first caught COVID-19 in March. He was tested for the coronavirus after he developed a cough, sore throat, fever, and a headache for 3 days. He stayed in the hospital until he twice tested negative for the virus in mid-April.
On Aug. 15, the man returned to Hong Kong from a recent trip to Spain and the U.K., areas that have recently seen a resurgence of COVID-19 cases. At the airport, he was screened for COVID-19 using a test that checks saliva for the virus. He tested positive, but this time, had no symptoms. He was taken to the hospital for monitoring. His viral load — the amount of virus he had in his body — went down over time, suggesting that his immune system was taking care of the intrusion on its own.This article was originally found on webmd.com
