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 EPA ORD CoVID-19 website data report summarizes the results of lab studies on the inactivation of UVC light as emitted from two different light sources against SARS-CoV-2 and two surrogate viruses. 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, transportation authorities, and other stakeholders including the general public that may consider UVC light disinfection as a mode of disinfection of their spaces.
Description:
Second update to the ORD CoVID-19 Environmental Research website on UVC disinfection.
