As the COVID-19 pandemic continues to evolve, the Centers for Disease Control and Prevention (CDC) is monitoring the risk of the virus in destinations around the world and issuing travel recommendations. The CDC uses Travel Health Notices (THN) to alert travelers and other audiences to health threats and advise them on how to protect themselves. In this article, we'll explore how the CDC determines the level of a destination's COVID-19 travel health advisory and how to find apps that can help with monitoring and prevention. The CDC uses a variety of factors to assess the risk of COVID-19 in a destination.
These include the number of cases, the rate of transmission, and the availability of healthcare resources. The CDC also considers whether travelers are likely to be exposed to COVID-19 during their trip, such as through contact with infected individuals or by visiting crowded places. Based on this assessment, the CDC assigns a THN level to each destination. The THN levels range from 1 to 3, with 1 being the lowest risk and 3 being the highest. Level 1 destinations have minimal or no risk of COVID-19 exposure, while Level 3 destinations have high risk of exposure. For destinations with a population of 100,000 people or less, the CDC issues health advisories for all three levels. The CDC also provides information on arrival notices for certain countries.
These notices provide information on any additional requirements for travelers entering those countries, such as proof of vaccination or a negative COVID-19 test result. The CDC also has an interactive global map that provides up-to-date information on travel recommendations for each country.

national, resident permanent legal or traveling to the United States on an immigrant visa, you must show proof that you are fully vaccinated against COVID-19 before flying to the United States from a foreign country. Travelers who have recovered from COVID-19 in the past 90 days don't need to be tested before or after their trip.
