Does any of this really work? Is there any real science that this reduces the rates of transmission or is this just feel good nonsense? I'm sure that every soap company has studies of poring their soap into a pietri dish and seeing it kill many of the bugs. The question that I am asking is, are there any real and quality studies that measure real world effect?
