Alveolar echinococcosis is an indigenouszoonosis caused by the growth of the larval stage of a small tapeworm, Echinococcus multilocularis. Despite a low incidence in Belgium, with about 10 cases on average recorded per year, this parasitosis poses a real public health problem because it often remains difficult to diagnose and is potentially fatal in the absence of treatment. General practitioners are on the frontline, but they do not always know enough about the disease, which causes a delay in the diagnosis and impacts the prognosis. The present study aims to assess the level of knowledge of alveolar echinococcosis among general practitioners in the province of Liège via a questionnaire, on the one hand, and to increase their level of knowledge via a formative intervention using a video capsule, on the other hand. We have performed a randomized controlled experimental study, which showed that general practitioners in the province of Liège have limited knowledge on alveolar echinococcosis. This mainly concerns symptomatology, diagnostic tools and treatment. The formative intervention carried out allowed increasing their level of knowledge about this disease.
