I suppose you can also get sick from being outside. There are germs everywhere! Maybe also from touching other people. Do you ever touch things other people touch?

I would say the "big leap" you are taking is that everybody will get some irreversible contagious disease. Really? You know we deal with bacteria all the time, right? In fact, you have quite a few on your skin. I'm pretty sure you continuously wash your skin though, to prevent yourself from getting ill.
