Deactivating COVID-19 Virus Cough Droplets with UV-C Lamps


Using supercomputer numerical modeling of saliva droplets’ diffusion produced by coughs, researchers in Italy explore deactivating COVID-19 virus particles via UV-C light.

One of the primary ways the COVID-19 virus is transmitted is via airborne diffusion of saliva microdroplets, so it is paramount to find methods to kill the virus in airborne microdroplets.

The extreme confusion that abounded at the beginning of the pandemic about safe social distances, mask-wearing, and social behavior inspired Marche Polytechnic University researchers, who happen to be intrigued by saliva droplet diffusion, to search for answers and ways to help.
