To help prevent the spread of COVID-19 and help our country cope during the pandemic, CDC has occasionally issued legally binding orders and regulations.

Air passengers, 2 years or older, traveling to the United States from another country must present a negative COVID-19 test result or documentation of recovery from COVID-19 before boarding their flights. For passengers that are not fully vaccinated and are ages 2 or older, a negative COVID-19 viral test result from a sample taken no more than 1 day before travel is required.
