[The So-called "fox Tapeworm"]

The so-called "fox tapeworm" (Echinococcus multilocularis), the causative agent of a severe disease in man (alveolar echinococcosis), is presently under public discussion in Switzerland. Therefore, actual information is provided on the life cycle of the parasite, epidemiology, disease in humans, symptomatology, diagnosis, therapy and prophylaxis. It is recommended that in endemic regions hunters handling foxes should wear protective gloves, dead foxes should be transported in plastic bags and wild fruits, berries and vegetables should be carefully washed and--if possible--heated to more than 70 degrees C for some minutes prior to consumption. After contact with foxes or other final hosts (dogs, cats) infected with E. multilocularis, persons should be monitored with the highly sensitive and specific Em2-ELISA for serum antibodies aiming at an early diagnosis and treatment of a potential infection.
