Carry on with your plans, but with certain safeguards and travel tips in mind, say UC Davis Health experts.

“The best advice is to delay travel until you are fully vaccinated,” said Natascha Tuznik, an infectious disease specialist at in the Department of Internal Medicine. “And, even if you are vaccinated, remember that most public transportation still requires masks—including planes and airports.”

Tuznik is planning to travel with her husband and young children in October and is hopeful their trip to Disney World will be one for the memory books. However, she is prepared in case the Delta variant or other rapidly changing COVID-19 conditions cause another shutdown.

“Chance favors the prepared mind,” said Tuznik, quoting 19th century vaccine pioneer Louis Pasteur. “There are new pandemic developments all the time. My recommendation is to buy travel insurance in case there is a surge that complicates or cancels your vacation plans.”

Tuznik recommends the following tips:

  • Children over 2 and under 12 should wear masks in public places as should anyone who isn’t vaccinated.
  • Unvaccinated individuals should get tested three days before traveling and maintain a physical distance of 6 feet, if possible.
  • Follow all state and localrecommendations or requirements after travel.
  • When traveling internationally, research COVID-19 restrictions before you go. You may need a recent negative COVID-19 test before you board your flight and you WILL need a negative COVID-19 test before boarding your flight home to the U.S.

Quarantine when you return home:


If you have traveled internationally and are vaccinated, you should test 3-5 days after return and, if negative and asymptomatic, you do not have to quarantine. Domestic travelers don’t need to be tested upon returning home. See CDC travel tips for vaccinated individuals.

Not vaccinated?

CDC advises to get tested within 3-5 days and stay home for a full 7 days, even if you test negative. If you don’t test, you must stay home for a full 10 days. Follow CDC traveler guidelines for updates to recommendations.

The CDC offers a map displaying travel recommendations by destination to help with decisions on whether or not to travel to certain countries during the pandemic.
