Factors that may contribute to reinfection include waning immunity and emerging new variants. But this new rash would appear after COVID-19 is gone. Its tough to pin down how soon people are susceptible to reinfection, Shaw said. The White House later revealed that he tested positive again on Saturday in what has become known as a rebound case.
