Abstract

The in vitro virucidal efficacy of povidone-iodine products against avian influenza viruses was investigated. The viral infectious titers were reduced below the detection limit by incubation with the povidone-iodine products used in this study (PVP-I solution, PVP-I scrub, PVP-I palm, PVP-I gargle, PVP-I throat spray and PVP-I solution for animals) for only 10 seconds. These results indicate the virucidal efficacy of these povidone-iodine products against avian influenza viruses.
