Project background

Hepatitis E is increasingly recognized as a foodborne zoonotic disease transmitted via pork products. Little information was available about the incidence and impact of hepatitis E in humans in Switzerland.

Our work

SAFOSO in collaboration with the University of Zurich conducted a quantitative assessment of the risk of hepatitis E to consumers from the consumption of domestic pork and wild boar products. In addition, the objective was to assess the burden of disease of human hepatitis E in Switzerland.


The results of our study contributed to the decision to make hepatitis E in humans a notifiable disease and triggered a discussion to include hepatitis E virus in the national monitoring program for pork products. The results of the study have also been published internationally and can be found on our website.
