I have been answering a bunch of questions about this virus. There is a lot of confusion, and there are a few questions that I seem to hear over and over. So, here is a simple primer. 1. Why is personal distance of 6 feet a thing? The measles virus can be spread through the air because it can literally float on the microscopic dust in the air. If you walk into a room in which someone with measles had coughed hours before, it is possible to get the measles from inhaling the floating virus.
