What may work is using ultra violet rays to clean the air. I know they are already using the technology in US bases. How come, our so called scientific experts including, Dr. Anthony Fauci has not said anything about cleaning the air in enclosed spaces like grocery stores, casinos, hospitals? You would think that would make a lot more people safer from contracting the Corona Virus and a much better solution than social distancing? Remember, the Corona Virus when airborne and being circulated by the airconditioning, will remain airborne, to infect people. Masks may protect you but, maybe not, depending on the mask you are wearing. Watch for it, one day, one of these extreme liberal idiots dictating policies on Corona Virus will finally, figure it out. Give it one whole year. Maybe, I am being too optimistic. And it is not President Donald Trump to be blamed as he is not a scientific expert to begin with.
