And of course, I am glad it doesn't (hasn't yet?) . Hi All, I see daily people going through trash cans looking for recyclables. These people do not wear gloves, and their hands go through all sorts of trash, including food leftovers. I imagine at some point they may rub their faces with their hands, and they may come into physical contact with many others in many different ways. In my very rudimentary knowledge of Biology and Epidemiology , this seems to provide " perfect storm " conditions for an epidemic. Now, I have seen this going on for years. Why isn't this creating an epidemic?
