Reduction of Viral Infectivity

The SARS-CoV-2 virus which causes COVID-19 was found to spread via aerosols, large droplets, or contact with infectious secretions. Environmental contamination with aerosolized droplets containing this pathogen can serve as a reservoir for infection and must be controlled by effective disinfection protocols. Minimizing the degree of environmental contamination with highly effective decontamination measures would aid in the overall containment efforts of the COVID-19 pandemic. We validated the use of the photocatalytic oxidation method to inactivate enveloped RNA viruses using dengue virus type 2 (DENV2) as a safe surrogate for the highly pathogenic SARS-COV-2 virus. Our results showed that there was a significant reduction in the infectivity of the DENV2 after being exposed to the photocatalytic oxidation treatment. This suggests that the photocatalytic oxidation treatment might reduce the spread of viral infections and improve the containment of pandemics such as COVID-19.
