Travelers should continue to follow CDC guidance for traveling, along with state and local travel return requirements. After a trip, travelers are recommended to self-monitor for COVID-19 symptoms; and isolate and get tested if you develop symptoms.
If you plan to travel internationally, you will need to get a COVID-19 viral test (regardless of vaccination status) before you travel by air into the U.S., and show your negative result to the airline before boarding. The CDC recommends that all travelers returning from international travel get tested for COVID-19 3-5 days after travel.
If you are not fully vaccinated, the CDC also recommends that you get tested for COVID-19 3-5 days after returning from travel (domestic or international), and to stay home and self-quarantine for 7 days after travel. If you don’t get tested, stay home and self-quarantine for 10 days after travel.
