Reducing spread of infections with a Photocatalytic Reactor

Improved control and reduction of healthcare-associated infections (HAI) are perpetual concerns in hospitals and other healthcare settings, including non-hospital residential facilities such as nursing homes and correctional facilities. Additionally, the recent emergence of the coronavirus disease 2019 (COVID-19) pandemic, which is caused by the novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), highlights the need for safe and effective methods to decontaminate surfaces to control infection spread in hospitals and the community. To address these critical needs, we have been working on multiple experiments to test the efficacy of using a photocatalytic reactor decontamination method that produces reactive oxygen species to disinfect contaminated surfaces in a hospital and a laboratory setting. Our data showed a significant reduction in S. aureus (bacterial) growth in a hospital room that was treated with a photocatalytic reactor compared with a control room. Moreover, there was a significant reduction in the infectivity of viruses when treated with the photocatalytic reactor. Collectively our data suggest the potential efficacy of using photocatalytic reactors in reducing the spread of infections.
