How long does it take for UV light to kill viruses?

Studies conducted by researchers at John Hopkins University using UV light on “high touch” public spaces in hospitals such as bed rails, tray tables, and vitals monitors have revealed that it only takes 15 minutes for these objects to be disinfected using UV light. Remarkably, the study revealed 25 out of 27 high-touch surfaces used in the study were devoid of any bacteria after being exposed to UV light. To destroy bacteria, ultraviolet radiation is used as a disinfectant by utilizing a 200 to 300 nanometre range. To eradicate a virus, extremely high levels of UV light would be required and the amount of UV required and the time needed would be dependent on many factors, such as the shape and type of material that the virus is found on. Current UV devices are insufficient to adequately kill viruses. Efforts are being made to create a portable UV device that is capable of releasing high-intensity rays able to kill viruses, such as the SARS-CoV-2 virus.

UV-C lights are available to consumers in a variety of different products including UV-C lamps and wands. The length of time needed to destroy viruses and bacteria is unique to each device. Each UV-C device will state on the packaging or the packaging insert how long it will take to sanitize the product and how close the object will need to be held to the device. UV light is only effective on smooth, flat surfaces and cannot effectively disinfect rounded objects such as the buttons of a remote control, nor can it get into crevices. Other forms of disinfection would be required to adequately clean these objects.
