    Updated Jan. 20, 2022

    CDC has updated isolation and quarantine recommendations for the public, and is revising the CDC website to reflect these changes. These recommendations do not apply to healthcare personnel and do not supersede state, local, tribal, or territorial laws, rules, and regulations.

    Reinfection with the virus that causes COVID-19 means a person was infected, recovered, and then later became infected again. After recovering from COVID-19, most individuals will have some protection from repeat infections. However, reinfections do occur after COVID-19. We are still learning more about these reinfections. Ongoing studies of COVID-19 are helping us understand:

    • How often reinfections occur

    • Who is at higher risk of reinfection

    • How soon reinfections take place after a previous infection

    • The severity (how serious the infection is) of reinfections compared with initial (the first) infections

    • The risk of transmission to others after reinfection
