Description:Updated Apr. 28, 2021
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 November 21, 2020, CDC adapted its 3-level notice system to a 4-level system for COVID-19 and updated criteria used to determine THN levels. The system was updated to align with the same incidence rate or case count thresholds adopted by recognized public health organizations and shares a common 4-level structure with the U.S. Department of State’s Travel Advisory system.
