Due to the large number of known viral pathogens and for methodical reasons, it is not possible to test disinfectants for their activity against all individual viruses directly. Hence, in accordance with the joint guidelines of the RKI and DVV, test viruses are selected for determining the efficacy. These viruses are representative for Germany and possess characteristic properties.
Viruses for testing virucidal activity against enveloped viruses:
BVDV (Bovine viral diarrhoea virus) and vaccinia virus.
Viruses for testing virucidal activity:
Adeno-, polio-, polyoma- and murine norovirus.
In contrast, the European Norm EN 14476 uses the test viruses adeno-, poliovirus and murine norovirus (MNV) for determining virucidal activity.
