Virucidal Efficacy of a Disinfectant for Use on Inanimate Environmental Surfaces For Hepatitis B Virus

The U.S. Environmental Protection Agency (EPA) requires an infectivity assay to be conducted to determine the virucidal efficacy of disinfectants used on hard, inanimate environmental surfaces. Presently, there are no reliable in vitro infectivity assays available for Hepatitis B virus. The EPA has approved the use of surrogate viruses to be used as a model… Read More
