Description:Updated Oct. 27, 2020
Confirmed and suspected cases of reinfection of the virus that causes COVID-19 have been reported, but remain rare.
In general, reinfection means a person was infected (got sick) once, recovered, and then later became infected again. Based on what we know from similar viruses, some reinfections are expected. We are still learning more about the virus that causes COVID-19. Ongoing COVID-19 studies will help us understand:
• How likely is reinfection
• How often reinfection occurs
• How soon after the first infection can reinfection take place
• How severe are cases of reinfection
• Who might be at higher risk for reinfection
• What reinfection means for a person’s immunity
• If a person is able to spread COVID-19 to other people when reinfected
