[Alveolar echinococcosis in the French province of Ardennes: isolated case or new focus?].

The first three autochthonous cases of alveolar echinococcosis were diagnosed in the Ardennes area (France). This is the most occidental localization of this disease in Northern Europe. The authors discuss these cases with an epidemiological regard. They are looking for relationships with natural parasitic cycle in the neighbouring country Belgium and their consequences on local public health in the future.
