UV light kills the COVID-19

the quickest of any solution. The virus dies in seconds with no fluid or other residual. This would work very well in empty airplanes, classrooms, hospital rooms, nursing homes, hotel rooms, supermarkets, restaurants, prisons, large offices … anywhere as long as no one is there when shining the light.

Ultraviolet light at wavelengths between 200 and 280 nanometers, also known as UV-C light, “causes DNA either to change shape, or acts like molecular scissors,” says Beckett, . “It will cut that genetic material and cause little nicks in it.”

Complex organisms and even some bacteria can repair those small lacerations themselves. Viruses, which are molecularly much simpler than bacteria, don’t stand a chance.

UV-C light is a long-established disinfectant in health care settings. Over the last 10 years, hospitals around the world have adopted machines that sterilize rooms and equipment with powerful blasts of light. Because UV-C can also cause sunburn and the cell mutations that lead to skin cancer, most machines currently in use can only work safely and effectively in rooms empty of people, making them impractical for use in high-traffic areas like waiting rooms and other common spaces.
