to avoid falling ill on your vacation: take care. schedule a full 24 hours after landing in your new location to unwind sleep and take care of yourself. a nonstop mentality wears down our immune systems and lowers our resistance to staving off infectious diseases. take flight. it's true that spending time in confined spaces can expose us to infection. but modern aircraft use excellent filters: 50% of the air is fresh and the other 50% has almost all of the infectious particles filtered out. so while it might be bad news to sit right next to someone who is obviously sick most of us will do just fine on the plane itself.
