Risk of COVID-19 During Air Travel

Educational Objective
To understand the risks of COVID-19 infection during air travel
1 Credit CME

The risk of contracting coronavirus disease 2019 (COVID-19) during air travel is lower than from an office building, classroom, supermarket, or commuter train.

The virus that causes COVID-19 is emitted when someone talks, coughs, sneezes, or sings, mainly in droplets that can be propelled a short distance, and sometimes in smaller aerosol particles that can remain suspended and travel further. Another person can be infected if these particles reach their mouth or nose, directly or via hands. Transmission via surface contact is also important in some cases.
