Survival and disinfection of an enveloped surrogate virus on Tyvek suits used for health care personal protective equipment.
The survival and disinfection of bacteriophage Φ6, an enveloped surrogate virus, was evaluated on Tyvek suits used as health care personal protective equipment. After 6 hours there was 2-log10inactivation of virus on Tyvek suits at both 40% and 60% relative humidity. Both hypochlorite and quaternary ammonium produced a >3.21- and >4.33-log10reduction of the virus, respectively, after 1-minute contact time. Enveloped viruses can survive on Tyvek suits beyond the length of a single patient care encounter, but they can be inactivated by chemical disinfectants.
