Abstract:	The present study was undertaken in 1980 in order to assess the prevalence of Schistosoma haematobium (Bilharz) among employees on the South Chad Irrigation Project (Borno State, northeastern Nigeria), particularly the agricultural workers who could constitute a source of infection within the irrigated area should the snail intermediate hosts of the parasite become established there. The overall prevalence of S. haematobium in the 254 male subjects examined was 31 percent. This is strikingly consistent with previously measured prevalence rates in the region. There were no marked patterns of infection associated with ethnicity or religion, although the number of samples examined was possibly too small to detect any such trends. The distribution of housing and sanitation among infected persons followed the general pattern of all respondents. Bibliogr.
