As a result of a court order, effective immediately and as of April 18, 2022, CDC’s January 29, 2021 Order requiring masks on public transportation conveyances and at transportation hubs is no longer in effect. Therefore, CDC will not enforce the Order. CDC continues to recommend that people wear masks in indoor public transportation settings at this time.

  • Everyone aged 2 years or older—including passengers and workers— should properly wear a well-fitting mask or respirator in indoor areas of public transportation (such as airplanes, trains, buses, ferries) and transportation hubs (such as airports, stations, and seaports), especially in locations that are crowded or poorly ventilated such as airport jetways.

Contact Information – ALL Travelers

   REQUIRED

All air passengers to the United States will also be 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:
