Travel Guidance for COVID-19

CDC Travel Guidance Within the United States

Anyone who is fully vaccinated against COVID-19 can travel within the United States without needing a COVID-19 test result or to self-quarantine after travel. We must all still take precautions while traveling, including wearing a mask, avoiding crowds, socially distancing, and washing hands frequently. View the latest CDC domestic travel guidance.

CDC Order Requiring Testing Before International Travel 

Effective Dec. 6, 2021, if you plan to travel internationally, you will need to get a COVID-19 viral test (regardless of vaccination status or citizenship) no more than 1 day before you travel by air into the United States. You must show your negative result to the airline before you board your flight. View the latest CDC international travel guidance.

Know when to delay your travel

Travelers with a known exposure to COVID-19 should delay travel, quarantine themselves from other people, get tested, and monitor their health.

You should not travel if you are sick or you tested positive for COVID-19 and haven’t ended isolation, even if you are fully vaccinated.

Check travel restrictions at your destination

State, local, and territorial governments may have travel restrictions in place, including testing requirements, stay-at-home orders, and quarantine requirements upon arrival. To help slow the spread of COVID-19, it is important that you follow these travel restrictions. 

For up-to-date information and travel guidance, check the state, territorial, tribal and local health department where you are, along your route, and where you are going. Prepare to be flexible during your trip as restrictions and policies may change during your travel. 

Travel can increase your chances of getting COVID-19. Staying home is still the best way to protect yourself from COVID-19. Stay home if you are sick or if you have been around someone with COVID-19 within the past 14 days. For more information on traveling review the CDC’s travel guidance.

Domestic Travel Guidance

Travel increases the chance of getting and spreading COVID-19. Fully vaccinated travelers are less likely to get and spread COVID-19. CDC recommends delaying travel until you are fully vaccinated. All travelers should follow CDC recommendations for vaccinated and unvaccinated people.

Wearing a mask over your nose and mouth is required in indoor areas of public transportation (including airplanes) and indoors in U.S. transportation hubs (including airports).

Check to see if there are a lot of COVID-19 cases at your destination.

The more cases at your destination, the more likely you are to get infected during your travels.

Are you or someone you live with at a higher risk for COVID-19?

If you become infected while traveling, you may become very sick while you are traveling. You can also spread the virus to your loved ones when you get home. 

Check to see if your destination has local requirements or restrictions for travelers.

Some places have requirements for travelers, like quarantining for 14 days after you travel. Check state, territorial, tribal, and local public health websites for information before you travel.
