Travel can increase your chances of getting and spreading COVID-19. We ask all visitors to respect the wishes and public health guidelines of their local destinations. Guidance may vary county by county, so it’s important to plan ahead, be prepared, and be flexible.

Things to consider

  • Travelers who are up to date on recommended COVID-19 vaccine doses are less likely to get and spread COVID-19. 

    • Vaccinated travelers do not need to get tested before or after travel within the United States unless their destination requires it. Check local requirements for testing prior to planning travel.

    • International travel poses additional risk. All travelers should get tested three to five days after traveling internationally.  As of December 6, 2021, all air passengers, regardless of vaccination status, must show a negative COVID-19 test taken no more than one day before travel to the United States.

    • Travelers who are up to date on their COVID-19 vaccines do not need to self-quarantine after travel.

    • Everyone age 2 and older must wear a mask on planes, buses, trains, and other forms of public transportation traveling into, within, or out of the United States, and in U.S. transportation hubs such as airports and stations. This is required by federal law for both vaccinated and unvaccinated people.

    • All travelers should follow CDC’s recommendations for traveling safely, including keeping 6 feet of distance from others and washing hands frequently.

  • Non-essential travel is not recommended for people who are not up to date on COVID-19 vaccinations.

  • Find out if COVID-19 is spreading where you’re going and always check restrictions in the area to which you are traveling. To get the most up-to-date information on local orders and variances, contact the area’s local public health agency.

  • If you or those you are traveling with are at higher risk for serious illness from COVID-19, consider limiting your travel.

  • Traveling to places where there is widespread transmission or to places where you intend to participate in large gatherings increases your chances of being exposed to COVID-19. 

  • For any trip, consider what you will do if you become ill while you’re away. You may need to isolate or quarantine away from home if you develop symptoms or are exposed to the virus while traveling.

When to avoid travel

  • If you are sick.

  • If you tested positive for COVID-19.

    • If you have symptoms, do not travel until 10 full days after your symptoms started. If you do not have symptoms, do not travel until 10 full days after you tested positive.

  • If you have been around someone with COVID-19 and haven’t ended quarantine.

    • Do not travel until you have finished quarantining for five full days after exposure. It is best to avoid travel for a full 10 days after your exposure.

  • If you are waiting for results of a COVID-19 test.

    • If your test comes back positive while you are away from home, you will need to isolate and postpone your return until ten full days have passed since your symptoms started or you tested positive. Your travel companions may need to quarantine.

  • Do not travel with someone who is sick.

People who are sick, have recently tested positive for COVID-19, or have been exposed to a person with COVID-19 pose a risk to others and should not travel.

If you become sick or are exposed to COVID-19 while traveling in Colorado

In Colorado, the local public health agency or state public health agency may issue public health orders to quarantine or isolate if you become ill or are exposed to someone with COVID-19 while you are visiting.

Public health orders may limit your travel or even require you to stay in Colorado during your quarantine or isolation, at your own expense. This means you may not be able to leave the state, regardless of how you travel (e.g. private car or airplane). This ensures not only your safety but the safety of those you may come in contact with on your trip home.
