Travel increases your chances of spreading and getting COVID-19. Some travel activities, like the transportation you choose and where you stay, can increase your risk of getting COVID-19. Know your travel risk. Your chances of getting COVID-19 while traveling also depends on whether you and those around you take steps to protect yourselves and others, such as wearing masks and staying 6 feet away from people outside your travel group (social distancing). Airports, bus stations, train stations, and rest stops are all places travelers can be exposed to the virus in the air and on surfaces. These are also places where it can be hard to social distance. In general, the longer you are around a person with COVID-19, the more likely you are to get infected.
Air travel requires spending time in security lines and airport terminals, which can bring you in close contact with other people and frequently touched surfaces. Most viruses and other germs do not spread easily on flights because of how air is circulated and filtered on airplanes. However, social distancing is difficult on crowded flights and sitting within 6 feet of others, sometimes for hours, may increase your risk of getting COVID-19. How you get to and from the airport, such as with public transportation and ridesharing, can also increase your chances of being exposed to the virus.
Bus or train travel
Traveling on buses and trains for any length of time can involve being in crowded terminals and sitting or standing within 6 feet of others, which may increase your risk of getting COVID-19. If you choose to travel by bus or train, learn what you can do to protect yourself on public transportation.
Making stops along the way for gas, food, or bathroom breaks can put you and your traveling companions in close contact with other people and frequently touched surfaces.
You may have to stop less often for food or bathroom breaks, but RV travel usually means staying at RV parks overnight and getting gas and supplies at other public places. These stops may put you and those with you in the RV in close contact with others.
If you plan to travel internationally, you will need to get tested no more than 3 days before you travel by air into the United States (US) and show your negative result to the airline before you board your flight, or be prepared to show documentation of recovery (proof of a recent positive viral test and a letter from your healthcare provider or a public health official stating that you were cleared to travel).
On January 12, 2021, CDC announced an Order requiring all air passengers arriving to the US from a foreign country to get tested no more than 3 days before their flight departs and to present the negative result or documentation of having recovered from COVID-19 to the airline before boarding the flight. Air passengers will also be required to confirm that the information they present is true in the form of an attestation. This Order is effective as of 12:01am EST (5:01am GMT) on January 26, 2021.
