OBJECTIVE: Mass systematic screening for alveolar echinococcosis (AE) of the liver in the Haut Cantal endemic area.
MATERIAL AND METHODS: Targeted population was composed of the members of the Mutualité Sociale Agricole of the area, from 16 to 65 years old. 2077 notifications were sent, corresponding to 20% of the population of this area, defined by a triangle between Egliseneuve d'Entraigues, Riom ès Montagne and Saint Flour. Two screening tests were performed: Elisa serology test and liver ultrasound examination.
RESULTS: Participation levels were relatively low-ultrasound: 18.92%, serology: 17%. Among 350 liver examinations, 2 suspicions of AE were found: CT and serology confirmed the diagnosis in the first symptomatic patient; CT and biopsy confirmed the diagnosis in the other asymptomatic patient in whom serology was normal.
CONCLUSION: Ultrasound screening showed at least a 0.57% prevalence of AE, i.e., 2 cases out of 350. This low rate however confirms that Haut Cantal is an endemic area, but with a lower incidence rate than in other endemic areas.
