Myth: UV rays from sunlight kill the new coronavirus

But although the heat of sunlight can weaken the outer layer of the coronavirus and help kill the virus on surfaces, it can take a long time and in the meantime a person could touch the surface, touch their nose, mouth or eyes and become infected. It is not safe to assume that sunlight will kill a virus when you are around others on a sunny day. Going to the beach on a sunny day and assuming the sunlight will kill virus is not a safe assumption because the virus can still spread from person to person when the virus is shed as an infected person talks or breathes or coughs.
