Echinococcus in red foxes

The zoonotic dwarf fox tapeworm Echinococcus multilocularis has never been detected in mainland Norway.

The objective of the surveillance program is to document freedom of E. multilocularis (i.e. a prevalence below 1% at a confidence level of at least 95%) in mainland Norway.


The prevalence of Echinococcus multilocularis was analysed by PCR of faecal samples from 495 red foxes (Vulpes vulpes) and 11 gray wolfs (Canis lupus) collected during the licensed hunting season in 2017. E. multilocularis was not detected in any of the samples corresponding to a prevalence in carnivore hosts below 1% with at a confidence level of at least 95%.
