Irradiating COVID-19 Cough Droplets with UV-C Lamps

The extreme confusion at the beginning of the pandemic inspired Marche Polytechnic University researchers, who happen to be intrigued by saliva droplet diffusion, to search for answers and ways to help. In Physics of Fluids, they describe using a supercomputer to do numerical modeling of cough droplets irradiated by UV-C light. They also report exploring the social distances required to prevent virus transmission.

UV light shows promise in mitigation of costly swine virus

Experiments testing the ability of ultraviolet light to stop the spread of a costly virus for pork producers has shown promise, according to an ISU research team. Ultraviolet light analyzed in experiments irradiates aerosolized droplets of the virus that causes porcine reproductive and respiratory syndrome. The researchers hope to scale their experiments up to a size comparable to pork production facilities.

Biomedical engineers to test ultraviolet light’s ability to kill coronavirus

The idea of UV sterilization is not a new one, but little or no scientific data about its potency against COVID-19 have been collected, until now. Thanks to a one-year, $182,728 grant from the National Science Foundation, researchers at Binghamton University, State University of New York are beginning to test UV’s effectiveness.
