That way, intestinal parasitoses prevalence was determined in Santa Luzia. Altogether, 3.221 tests were analyzed. 34.6% had parasitosis, of these, 40.39% were of specie Endolimax nana, the most frequent protozoan, and 2,15% were Ascaris lumbricoides, the helminth more present. In positive tests, 9.52% presented polyparasitoses and 90.48% monoparasitoses. It was concluded that more than 30% of patients were infected with some specie of parasite; protozoans are more prevalente than helminths; and the implementation of integrated actions is necessary to reduce the infestation of these parasites in the population.
