As a prelude to a national campaign to control schistosomiasis in Togo, mass screening of school children in 22 prefectures was undertaken to determine the extent of endemic schistosomiasis. Children were randomly selected for testing. In each case, stool examinations using by the Kato-Katz method and urine tests (centrifugation of 10 ml) were performed to detect Schistosome eggs. A total of 2511 children were tested. The sex ratio was 1.7 and mean age 10.4 years (range: 5 to 20 years). The incidence of schistosomiasis was 26.7 p. 100. Schistosoma haematobium was the most widespread and active Schistosome species, being endemic in all locations studied. The incidence of Schistosoma haematobium ranged from 0.6 to 72 p. 100 (national mean: 25.5 p. 100). Schistosoma mansoni was prevalent in only 12 prefectures (range 0.6 to 10 p. 100; national average 2.2 p. 100). The rate of infection was highest in the age group between 10 and 20 years and the risk appeared to be significantly higher in males than in females (p < 0.05). This study confirmed the high incidence of schistosomiasis infection in Togo and identified hyperendemic areas in which control measures should be programmed first.
