a study of some factors influencing the epidemiology of urinary schistosomiasis at ifakara (kilombero district, morogoro region, tanzania).some factors influencing the epidemiology of urinary schistosomiasis were studied at ifakara between 1978 and 1980. ifakara is situated in the fertile plain of the kilombero river in the south-eastern part of tanzania. the overall prevalence of schistosoma haematobium infection among primary school children (6-19 years) in the ifakara agglomeration was 21% (730/3478). the highest prevalence was observed in both sexes in the age group 15-19 years. distinct variations in prevalence were found betw ...19836138972

the population biology and epidemiology of schistosome and geohelminth infections among schoolchildren in tanzania.a study of helminth infections was undertaken among 3244 schoolchildren from 28 schools in morogoro rural district, tanzania. schistosoma haematobium was the most common infection, followed by hookworms, ascaris lumbricoides, s. mansoni, and trichuris trichiura. infection prevalence of each species varied among schools and age groups, but not between sexes. there was no relationship between the prevalences of different infections among schools, except for a strong negative correlation between th ...19989861359
controlling schistosomiasis: the cost-effectiveness of alternative delivery strategies.sustainable schistosomiasis control cannot be based on large-scale vertical treatment strategies in most endemic countries, yet little is known about the costs and effectiveness of more affordable options. this paper presents calculations of the cost-effectiveness of two forms of chemotherapy targeted at school-children and compares them with chemotherapy integrated into the routine activities of the primary health care system. the focus is on schistosoma haematobium. economic and epidemiologica ...199410139471
