Lol, I hate to tell you this but if sunlight could substantially wipe out the virus we'd all be toast from the rays cooking us, that 's because the UV rays that can destroy viruses aren't the type for prolonged exposure to humans. They do have these types of lights and they are used in some hospital settings, now being implemented on some airplanes but not while humans are sitting there, you can't point one at you at home to get a tan...not without serious consequences. (I wrote all that in a round about way because I am to lazy to go look it all up right now)
