See all COVID-19 travel notices.

 

Do not travel internationally until you are fully vaccinated. Getting vaccinated
is still the best way to protect yourself from severe disease, slow the spread
of COVID-19, and reduce the number of new variants. CDC encourages you get a
COVID-19 vaccine booster dose if you are eligible. People who are not fully
vaccinated should follow additional recommendations before, during,
and after travel.


BEFORE YOU TRAVEL INTERNATIONALLY

Make sure to plan ahead:

 * Follow all airline requirements as well as any requirements at your
   destinationExternal Link, including mask wearing, proof of vaccination,
   testing, or quarantine. Requirements may differ from U.S. requirements. If
   you do not follow your destination’s requirements, you may be denied entry
   and required to return to the United States.


TESTING

   RECOMMENDED
 * If you are not fully vaccinated, get tested with a viral test 1–3
   days before your trip. 

Do NOT travel if…

 * You are sick.
 * You tested positive for COVID-19 and haven’t ended isolation.
   * After you end isolation, avoid travel until a full 10 days after your
     symptoms started or the date of your positive test if you had no symptoms.
   * If you must travel on days 6 through 10, properly wear a well-fitting
     mask when you are around others for the entire duration of travel. If you
     are unable to wear a mask, you should not travel during days 6 through 10.
 * You had close contact with a person with COVID-19 and haven’t ended
   quarantine.
   * Get tested at least 5 days after your last close contact and make sure your
     test result is negative and you remain without symptoms before traveling.
     If you don’t get tested, delay travel until a full 10 days after your last
     close contact with a person with COVID-19.
   * If you must travel before the 10 days are completed, properly wear
     a well-fitting mask when you are around others for the entire duration of
     travel during the 10 days. If you are unable to wear a mask, you should not
     travel during the 10 days.
 * You are waiting for results of a COVID-19 test. If your test comes back
   positive while you are at your destination, you will need to isolate and
   postpone your return until it’s safe for you to end isolation. Your travel
   companions may need to quarantine.


DURING TRAVEL


MASKS

   REQUIRED
 * Wearing a mask over your nose and mouth is required in indoor areas of public
   transportation (including on airplanes) traveling into, within, or out of the
   United States and indoors in U.S. transportation hubs (including airports).


PROTECT YOURSELF AND OTHERS

   RECOMMENDED
 * Follow all recommendations and requirements at your destinationExternal Link,
   including wearing a mask and staying 6 feet (2 meters) apart from anyone who
   did not travel with you.
 * Wash your hands often with soap and water or use hand sanitizer with at least
   60% alcohol. 


BEFORE TRAVELING TO THE UNITED STATES


TESTING - ALL TRAVELERS

   REQUIRED

Before boarding a flight to the United States, you are required to show the
following:

 * A negative COVID-19 test result taken no more than 1 day before travel.

Children under 2 years old do not need to test. There is also an option for
people who have documented recovery from COVID-19 in the past 90 days. Learn
more about these requirements.


CONTACT INFORMATION

   REQUIRED

All air passengers to the United States are also required to provide contact
information to airlines before boarding flights to the United States. This
strengthens a travel process already in place to rapidly identify and contact
people in the U.S. who may have been exposed to a communicable disease, such as
COVID-19. Access to travelers' contact information will allow U.S. federal,
state, and local health departments and agencies to share appropriate health and
public health information necessary to help keep the public safe.  


AFTER ARRIVAL IN THE UNITED STATES

You might have been exposed to COVID-19 on your travels, whether you traveled by
air, land, or sea. You might feel well and not have any symptoms, but you can
still be infected and spread the virus to others. For this reason, CDC
recommends the following:


ALL TRAVELERS

   RECOMMENDED
 * Get tested with a COVID-19 viral test 3–5 days after travel.
   * Find a U.S. COVID-19 testing locationExternal Link near you.
 * Self-monitor for COVID-19 symptoms; isolate and get tested if you develop
   symptoms.
 * Follow all state and local recommendations or requirements after travel.


IF YOU ARE NOT FULLY VACCINATED

   RECOMMENDED

In addition to the recommendations above

 * Stay home and self-quarantine for a full 5 days after travel.

If Your Test Result is Positive

Isolate yourself to protect others from getting infected. Learn what to do and
when it is safe to be around others.


IF YOU RECOVERED FROM COVID-19 RECENTLY

If you recovered from a documented COVID-19 infection within the past 90 days
(regardless of vaccination status), you do NOT need to get a test 3–5 days after
travel. People can continue to test positive for up to 90 days after diagnosis
and not be infectious to others. You also do not need to self-quarantine after
travel. If you develop COVID-19 symptoms after travel, isolate and consult with
a healthcare provider for testing recommendations.
