COVID-19 patients protected from reinfection for 3 months after recovery

“As expected from other small studies, prior infection provides protection, though maybe not complete, from subsequent infection,” infectious disease specialist Dr. Donald Forthal told UPI. Recovered patients have some level of protection “for at least the time period of this study, or about three months,” said Forthal, chief of the division of infectious diseases, [school of medicine] at the University of California, Irvine, who was not part of the NIH research.
