The samples analyzed in the countryside were confirmed as positive for schistosomiasis 150 (19.6%) and 241 samples (6.4%) respectively of the urban area, observing an average of 9 % of infectivity. The positive cases were more significant for schistosomiasis among residents in rural communities than in urban areas , with a result of 19.6 % and 6.4 % respectively.
