Description:Updated Nov. 21, 2020
CDC uses Travel Health Notices (THNs) to alert travelers and other audiences to health threats around the world and how to protect themselves. On November 21, 2020, CDC adapted its 3-level notice system to a new 4-level system for COVID-19 and updated criteria used to determine THN levels.
COVID-19 Travel Health Notice information can be found in two places:
• An interactive world map which shows COVID-19 travel recommendations by destination
• CDC’s COVID-19 Travel Health Notice webpage
This new 4-level system categorizes destinations, including international destinations and United States Territories, into the following four levels:
• Level 4: Very high level of COVID-19
• Level 3: High level of COVID-19
• Level 2: Moderate level of COVID-19
• Level 1: Low level of COVID-19
