Because of a bugs short lifespan ,most all bugs and more so viruses mutate very quickly.....in turn it means they are quite different from the first nasty little critter......:(
OK just curious though couldn't that happen in dark, no air, moist place where somebody does a number 1 or 2 constantly say like in a back ally corner by a building in the combat zone in Boston? Just think of the murky stink! It sure smells like a disease I kid you not. How do they ever manage to clean these places? Jet blasts of disinfectant from a hose?
