Impact/Purpose:
SARS-CoV-2, the causative virus of the CoVID-19 pandemic, is by now a highly studied pathogen, yet consensus is lacking on the effective dose to inactivate/kill this virus on surfaces using UVC light. Dose-response curves are lacking for this virus as well as many surrogates. Information of what doses can be realistically achieved in e.g., a metro car or bus to achieve disinfection are also lacking. This presentation summarizes the results of lab studies on the inactivation of UVC light against SARS-CoV-2 and a surrogate virus as well as results from a field study in collaboration with LA Metro that measured UVC doses at various locations in a metro car outfitted with UVC light generated devices. This information provides a first guidance on the ability of UVC light to inactivate SARS-CoV-2 and an assessment of the possible SARS-CoV-2 surrogates for UVC disinfection research. These results are of high relevancy to researchers, companies that work on UVC implementation, transportation authorities, and other entities including the general public that may consider UVC light disinfection as a mode of disinfection of their spaces.
