Аннотация
BACKGROUND: Hepatitis E virus (HEV) is the most common cause of acute viral hepatitis, and mainly transmitted via faecal-oral contamination or consumption of contaminated food products. However, limited data on the surface stability and HEV sensitivity to chemical disinfectants are available.
AIM: To establish an HEV-based carrier assay to evaluate its surface stability and the virucidal activity of nine surface disinfectants.
METHODS: A recently developed robust HEV-3 cell culture system for an HEV-based carrier assay.
FINDINGS: Alcohol-based disinfectants were insufficient to eliminate HEV infectivity, whereas disinfectants based on aldehyde, peracetic acid, oxygen, and/or quaternary ammonium inactivated HEV.
CONCLUSION: These findings have strong implications for the recommendation of evidence-based hygiene guidelines to reduce HEV transmission.
