How does this virus spread specifically? I've heard droplets and airborne transmission? Wouldn't the virus "die" if the droplet evaporates? When you sneeze without covering the face, thousands of droplets get in the air but they evaporate within a minute or so depending on the relative humidity and temperature. Does the virus live when it is a particulate all by itself without being suspended in liquids? I want to know the technical details of how these things transmit. I've spend many years developing microcontamination systems in multi-billion dollar silicon fabs - there is a lot of theory/empirical science that goes in engineering sub-class 1000 cleanrooms. If viruses are alive unsuspended in liquids, then what stop thems from attaching to foods (grocery store)? Deeper understanding of physical propagation can help us fight Coronavirus - so far we're just putting on the masks.
