All people in Washington state age 12 and older are eligible to receive the COVID-19 vaccine. Learn how to get vaccinated in King County, read more about vaccination for youth, and view Public Health's Vaccine Strategy.

King County is following the Centers for Disease Control and Prevention’s travel recommendations. This page provides general guidance along with local recommendations for travelers.

Travel recommendations and requirements

We recommend limiting non-essential travel to reduce the spread of COVID-19 if unvaccinated.

People who are fully vaccinated with an FDA-authorized vaccine can travel safely within the United States.

If you travel, these are the CDC’s recommendations depending on where you’re traveling and your vaccination status. Everyone should monitor for symptoms for 14 days and wear a mask, regardless of your vaccination status or where you’re traveling.

For Domestic Travel:

Domestic Travel Recommendations and Requirements Not Vaccinated Fully Vaccinated
Get tested 1-3 days before travel.  
Get tested 3-5 days after travel and self-quarantine for 7 days. Self-quarantine for 10 days if you don’t get tested.  
Self-monitor for symptoms.
Wear a mask and take other precautions during travel.

For International Travel:

International Travel Recommendations and Requirements Not Vaccinated Fully Vaccinated
Get tested 1-3 days before traveling out of the U.S.  
Mandatory test required before flying to U.S.
Get tested 3-5 days after travel.
Self-quarantine after travel for 7 days with a negative test or 10 days without test.  
Self-monitor for symptoms.
Wear a mask and take other precautions during travel.

Do NOT travel if you were exposed to COVID-19, you are sick, you test positive for COVID-19, or you are waiting for results of a COVID-19 test. Learn when it is safe for you to travel. Don’t travel with someone who is sick.


What to expect if you’re going to travel

Travel increases the chance of spreading and getting COVID-19. We recommend limiting travel at this time. For more information, check out CDC's Travel Guidance.

If traveling within the United States:

Most states do not require a test, but each state and country has their own COVID-19 guidelines, and requirements change frequently. Do research before you go.

If traveling internationally:

Proof of negative test is required for air travelers entering the United States: all travelers into the United States from another country are required to get tested no more than 3 days prior to flying. This includes U.S. citizens and residents. Travelers must show proof of a negative result or documentation of having recovered from COVID-19 to the airline prior to boarding.

Some countries are conducting exit screening for all passengers leaving their destination. Before being permitted to board a departing flight, you may have your temperature taken and be asked questions about your travel history and health.

Testing options for travelers

I am planning to travel. Do I need to get tested?

Please see the section above to see if you need to get tested before or after travel based on your vaccination status.

Should I travel now that I’m vaccinated?

People who are fully vaccinated with an FDA-authorized vaccine can travel safely within the United States. While the CDC says it is safe to do so, they still discourage non-essential travel as it can contribute to the spread of COVID-19, which is still moderate-to-high in most of the country.

What are some of my testing options?

Go to your health care provider or a private health clinic. Many private health clinics and health care providers will provide testing with travel documentation for an additional fee.

Seek rapid testing. There are multiple rapid testing options around the county, including at the Sea-Tac airport. Public Health cannot make recommendations for private testing options.

Do King County free testing sites provide travel testing? You can get tested at any of the Open Access testing sites in King County. However, it is not guaranteed that you will receive a result within 72 hours of departure at the Open Access testing sites. It's also not guaranteed that the results will meet the specific requirements for all countries. We recommend other testing options in these cases.

Our testing sites only offer whether COVID-19 was "Detected" or "Not Detected," along with the person's name, DOB, test type, and date tested. These sites are not intended to screen travelers.

If you need testing documentation or certification:

If you do get tested at an Open Access testing site, please note that the sites cannot provide documentation or signatures certifying your results. But when you retrieve your results online, you will find a printable document that shows the results were processed by a certified lab.
