The Centers for Disease Control and Prevention (CDC) continues to recommend that travelers take precautions against COVID-19 over the winter travel season.

Domestic Travel During COVID-19:

• Get up to date with your COVID-19 vaccines before you travel.
• Consider getting tested before travel.
• Follow CDC’s recommendations for wearing masks in travel and public transportation settings.
• Get tested after traveling, if your travel involved situations with greater risk of exposure such as being in crowded places while not wearing a high-quality mask or respirator.

International Travel to and from the United States:

• Protect yourself and others from COVID-19:
  • Get up to date with your COVID-19 vaccines before you travel.
  • Consider getting tested before travel.
  • Follow CDC’s recommendations for wearing masks in travel and public transportation settings.
  • Get tested after arrival.
• Countries may have their own entry and exit requirements.
• Non-U.S. citizen, non-U.S. immigrants: You must show proof of being fully vaccinated with the primary series of an accepted COVID-19 vaccine before you board your flight to the United States. Only limited exceptions apply.

International travelers should be aware that some countries continue to have COVID-19 entry requirements. For country-specific information on entry requirements, travelers should visit the U.S. State Departments COVID-19 website. Currently, China has the most travel requirements, with travelers having to provide a PCR COVID test 48 hours before travel and quarantining for eight days upon arrival.

Travelers can use this resource to find testing sites near them. Travelers should confirm their chosen testing facility can make an appointment in time for them to travel and can provide results that meet entry and travel requirements. Additionally, some international airports such as SFO offer testing on-site before you travel (see SFO COVID-19 Testing).
