Prevention of diseases transmitted by airborne droplets.

There are many diseases that are transmitted by airborne droplets. There are special tips and rules to help prevent disease. But all of them are not effective enough, since we cannot hide from the carrier of the disease. We can maintain personal hygiene: wash our hands after public places, transport, before eating, process fruits and vegetables before eating. Some people advise avoiding places where there is a large crowd of people. But the chances of getting infected even in a large crowd are very small and this is more paranoia than a remedy.
