Surface disinfectants are part of broader preventive strategies preventing the transmission of bacteria, fungi and viruses in medical institutions. To evaluate their virucidal efficacy, these products must be tested with appropriate model viruses with different physico-chemical properties under conditions representing practical application in hospitals. Considering that non-enveloped viruses such as noroviruses and enteroviruses are resistant to the majority of chemical disinfectants, only biocides with proven virucidal efficacy can be used.
