Description:

CDC uses Travel Health Notices (THNs) to alert travelers and other audiences to health threats around the world and advise on how to protect themselves.

On April 18, 2022, CDC updated its COVID-19 THN system. Level 4 will no longer be based on COVID-19 incidence or case count alone. It will be reserved for special circumstances, such as rapidly escalating case trajectory or extremely high case counts, emergence of a new variant of concern, and healthcare infrastructure collapse. Levels 3, 2, and 1 will still be primarily determined by 28-day incidence or case counts as outlined below.
