Six commercially available FFR models were contaminated with H1N1 influenza virus as aerosols or droplets that are representative of human respiratory secretions. A subset of the FFRs was treated with the aforementioned decontamination technologies, whereas the remaining FFRs were used to evaluate the H1N1 challenge applied to the devices.<h4 class=""h4"">Resultsh4>
All 3 decontamination technologies provided >4-log reduction of viable H1N1 virus. In 93 % of our experiments, the virus was reduced to levels below the limit of detection of the method used.<h4 class=""h4"">Conclusionsh4>
These data are encouraging and may contribute to the evolution of effective strategies for the decontamination and reuse of FFRs.
