This study was conducted on some underprivileged populations namely prisoners and camp residents to determine whether the conditions in which they live constitute risk determinants parasitic infections especially with gastrointestinal parasites. Results showed that 44.2 % of 436 camp settlers (adults/children/both sexes) were positive for intestinal parasites of which 74.0% were protozoa' and 26% were helminths Again 36.10 % of the 795 prisoners (adults/children) were found infected; 93 %were infected with intestinal protozoa and 6.9 % with intestinal helminth. Higher prevalence rates of gastro-intestinal infections was observed in the camp population, no sex or age related differences occurred. In decreasing order of prevalence parasites recorded were E coli, G. lamblia, Ehistolytica, H. nana, E vermicularis T. saginata, A. duodenale, S. mansoni, S. stercoralis, T. trichura and A. lumbericoides. Urine samples were also screened. S haematobium was detected in 9.5% of urine sample from the camp population and in 2.3% of urine samples from the prison population. No sex related differences were observed however significant age-related differences was evident as infection rate markedly decreased after 20< years of age. When blood samples investigated, Falciparum malaria was detected in 29.4% of the camp population and 12.69% of the prison population. No age or sex specific prevalence was evident. In general, 38.3 % of the whole population had single infection however double infection was detected in 5.3 % of the camp population and in 1.13% of the prison population. Double infection with the urine parasite S. haematobium and the intestinal protozoa E coli was observed in 1.89 % and with G. lamblia in 1.3 % and with the Cestode H. nana in 0.6 % .Analysis of data accordingtoethnic origin revealed no tribal related differences. It was concluded from the study that living in the these camps or the prisone environment does nopt constitute a risk factor for parasitic infections when compared with rates of infection observed in the general population as obtained from the literature.
