It’s probably in the best interest of someone who has yet to catch a cold or other virus to avoid being in close contact with someone who is literally spraying viruses into the air by coughing or sneezing. You can’t protect yourself from potentially inhaling what is in the air. Also, viruses survive on inanimate objects (like furniture) for a short while, so if one happens to land on your pillow and you put your face on it, you might suffer the consequences. If someone is sick, it’s better to put some distance between them and you. We have antibiotics to fight bacterial infections, but still the only thing around that defends against viruses is a vaccination. Unfortunately for me, I go into allergic shock when I have a flu vaccination…
