Schistosomiasis in Cross River State, Nigeria: 1. Prevalence and intensity of infection in Adim, Akamkpa Local Government Area.
Mid-stream urine was randomly collected from 248 subjects in Adim. Blood and protein concentrations were determined semi-quantitatively using Combi-7 reagent strips. The urine samples were then processed and any ova of Schistosoma haematobium present were counted per 10 ml urine. Fresh stool samples were also randomly collected, processed and examined for S. masoni and other helminthic ova. The prevalence of S. haematobium in the area was 43.5% and this was found to be age-related but not sex-related. Mean egg count was 137.2 per 10 ml urine. Intense haematuria of 250 ery/microliters and proteinuria of 500 mg/dl accompanied the high egg counts. The stool examination showed no cases of Manson's schistosomiasis but polyparasitism with other intestinal helminths was common particularly among children under 10 years old. This is the first report of urinary schistosomiasis in this area and the high prevalence rate is consistent with the rice farming occupation of the natives of the area. The sensitive nature and the case of application of the reagent strips in determining heavy infections by measuring haematuria and proteinuria is once again confirmed.
