Infectious disease epidemiologist Dr. Syra Madad joins Dr. Ian Smith to discuss reinfection, which is a hot topic with the report of a 33-year-old man in Hong Kong getting the virus for a second time.
Due to the limited number of studies on reinfection, Dr. Madad says there is a great deal that is unknown. She tells Dr. Ian it is not known if getting the virus a second time is rare or not. She also notes there have been instances of the second infection being more severe than the initial infection, but stresses there is a limited number of cases that have been studied.
"Can reinfection happen? Yes, it can. How often? That is still up in the air," the infectious disease epidemiologist says. Dr. Madad also notes how long COVID antibodies will last in the body and their level of immunity is still a question mark.
