Treatment with dry hydrogen peroxide accelerates the decay of severe acute syndrome coronavirus-2 on non-porous hard surfaces

Background Disinfection of contaminated or potentially surfaces has become an integral part the mitigation strategies for controlling coronavirus disease 2019. Whilst a broad range disinfectants are effective in inactivating severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), application low throughput areas that receive treatments. large surface often involves use reactive microbiocidal materials, including ultraviolet germicidal irradiation, chlorine dioxide, and hydrogen peroxide vapor. Albeit these methods highly SARS-CoV-2, deployment approaches creates unacceptable health hazards precludes treatment occupied indoor spaces using existing disinfection technologies. In this study, feasibility dry (DHP) SARS-CoV-2 on was evaluated. Methods Glass slides were inoculated with treated DHP between 5 25 ppb up to 24 hours. Residual infectious virus samples eluted from three replicates at each time point titrated African green monkey VeroE6 cells. Results comparison observed relatively high stability glass (control group), residual titers significantly reduced after receiving 120 minutes treatment. Conclusions The accelerated decay suggests can be method
