A cross-sectional study on the prevalence and intensity of schistosomiasis among sugar cane cutters in Zimbabwe.
A schistosomiasis prevalence and intensity survey was carried out among sugar cane cutters of Hippo Valley and Triangle, the two largest irrigated sugar estates in Zimbabwe. Urine and stool specimens were collected for determination of schistosomiasis infection from 1995 cane cutters. A total of 315 (15.8pc) cutters were found to be infected with Schistosoma mansoni while 163 (8.2pc) were found to be positive for S. haematobium. The arithmetic mean egg count (AMEC) and geometric mean egg count (GMEC) for the different age groups into which the cane cutters were divided was calculated. The prevalence and intensity of S. mansoni increased with age while the opposite was true for S. haematobium. The factors contributing to this observation are discussed.
