Reported cases of people getting reinfected with SARS-CoV-2, the virus that causes COVID-19, are rare in the U.S. and none have been confirmed by the federal Centers for Disease Control and Prevention. But researchers say studying possible reinfections could answer some big questions about the body’s natural immune response after being infected with the virus.

Back in February, when the sports world was still wondering how severe an outbreak of something called Covid-19 might be, a Colombian cyclist named Fernando Gaviria was finding out for himself.

People can catch COVID-19 twice. That’s the emerging consensus among health experts who are learning more about the possibility that those who’ve recovered from the coronavirus can get it again. So far, the phenomenon doesn't appear to be widespread—with a few hundred reinfection cases reported worldwide—yet those numbers are likely to expand as the pandemic continues.

Although patients who recover from Covid-19 will hope to have developed antibodies conferring protection against the virus, there remain questions about immunity and how long it lasts.

A case of reinfection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is described in a study published online Oct. 12 in The Lancet Infectious Diseases.

If you were counting on a coronavirus infection to keep you safe from COVID-19 without having to get a vaccine, scientists have some bad news: It won’t work.

The Nevada State Health Response team reported the first case of COVID-19 reinfection in the country during a press conference Friday afternoon.

Scientists at the University of Nevada, Reno School of Medicine (UNR Med), led by its Nevada State Public Health Laboratory (NSPHL) are studying a likely case of COVID-19 reinfection.
