[The prevalence of intestinal parasitoses among the users of the Health Center of Sousas District, Campinas, São Paulo (1986-1990)].

The prevalence of intestinal parasites was carried on users of the Health Center of Sousas District, Campinas, SP (1986-1990). From 770 observed medical records we verify 114 positive cases (14.8%) for protozoa, helminths and commensals. Ascaris lumbricoides (48.2%), Giardia lamblia (30.7%), Trichuris trichiura (18.4%) and Enterobius vermicularis (9.6%) were more prevalent in preschool children. The adults, what are the most numerous class, appeared few parasitised. The other parasites and commensals appeared with a prevalence like the traditional brazilian population surveys, except for the absence of tenids and low prevalence of Ancylostomatoidea. We propose the realization of routine stool parasitological examinations among the preschool children and the use of the primary health care data in parasitological survey.
