In the July 1992 issue of the Journal, Corachan and others described what they believed to be a previously unknown area of schistosomiasis transmission in Mali, West Africa. They primarily based their claim on “findings from a travelers' clinic” in Barcelona, where they treated returning tourists. They identified this area of transmission as the small Cercle of Bankass (6,875 square km) which is inhabited primarily by the Dogon people but also by other ethnic groups, including the Peul. Schistosomiasis has been diagnosed in Bankass for many years. For example, in December, 1966, the Ministry of Public Health and Social Affairs recorded 68 cases of Schistosoma haematobium in the Cercle of Bankasss and in March, 1967, 98 cases. In calendar year 1991, a total of 114 cases of schistosomiasis were reported there.
