[Alveolar echinococcosis in China: current data]

Very few information about alveolar echinococcosis in China is available outside the country. The aim of the authors is to give some precisions about the human cases and the infection in the natural animal hosts. It occurs in 3 distinct foci which comprise poor and remote rural areas. Approximately, 420 cases of human disease have been detected, and the most intense focus is Ningxia province in central China. In all areas, the adult tapeworm is frequently found in V. vulpes, V. corsac, and in the domestic dog. The intermediate hosts differ from an area to the others. Their infection rate is high in the central and the northern foci. More researches are needed for improving our knowledge about the epidemiology of the disease. But the actual major requirement is to apply control measures as health education and medical information.
