You really don’t understand viruses then
It is how all viruses spread. There is always a patient zero. The problem is where has that person been? How many people has he been in contact with? How many of them have come down Dick?
You just haven’t paid attention over the years
It’s true, I’m not a virologist.
In fact, the only thing I really know about viruses is that I had the flu once when I was 16. That was the sickest I’ve ever been, I could do nothing, I was in bed the whole time, don’t even know if I went to the bathroom or ate.
