[Intestinal parasite infections and schistosomiasis in a poor urban area, in townships of the sugar cane belt and in villages of the semi-arid area of North-East Brazil].
We determined the prevalence of intestinal parasite infections between 1993 and 1998 in the populations of a poor quarter of Recife (Pernambuco), in two townships in the sugar cane belt and in three villages of the semi-arid area far from the coast. Intestinal schistosomiasis was present in the sugar-growing area but was not observed in the populations inland that use dams to provide irrigation and fishing. Ascaris was very common in the city and the sugar cane belt and large numbers of hookworms were observed, especially in the sugar-growing area. These nematodes were very rare in the semi-arid area. This distribution probably results from both climatic conditions and human behavior. The high frequency of Amoeba cysts demonstrates that the peasants, farmers and fisherman living in these areas have poor hygiene practices. There are probably many, complex relationships between education, income, lifestyle and intestinal parasite infections.
