Prevention: Being in public, especially with air travel, there is a constant risk of getting infections. Air travel is worse since 75% of the air you breathe on a plane is recirculated. Little can be done about the air (masks help very little since viral particles pass through the mask easily, ) but washing your hands and using sanitizers frequently will help, since 80% of infections are passed thru the hands.
