Can You Get Coronavirus Again After You've Already Had It? “The answer — today — is that people appear to be contagious one to two days prior to getting sick, and for one to two weeks after getting sick,” said Dr. Stephen Gluckman, an infectious diseases physician at Penn Medicine and the medical director of Penn Global Medicine. (This timeframe generally goes for any contagious illness, not just COVID-19.)

“As we improve, the amount of virus we’re shedding into the environment drops off,” Gluckman said.
