As of November 21, 2020, there is a revised Travel Health Notice system for COVID-19 released by the Centers for Disease Control and Prevention (CDC) that lists recommendations for testing before and after international air travel.
It is now recommended that international air travelers get tested with a viral test at least 1-3 days before their flight to limit spread during travel. They should also get tested 3-5 days after traveling, and stay at home for at least 7 days. However, if the traveler does not get tested, it is recommended that they stay home for at least 14 days.
Aside from getting testing, travels should also take steps to reduce exposures and avoid higher-risk activities for at least 14 days before traveling. If they are experiencing symptoms of COVID-19, have tested positive for COVID-19, have been around a person with COVID-19, or are waiting for the results of a COVID-19 viral test, travelers should delay local or international travel.
Furthermore, travelers flying internationally should check with each airline, transiting airport and final destination for the latest safety guidelines prior to departure.
