| Summary: | An enteroparasitologic prevalence study based on a coproparasitologic analysis and the Graham test were conducted, in order to evaluate the children population (between 1-12 years old) from Colony Aurora, Province of Misiones. The 89.1% of children had parasites. A prevalence of 22.9% for
Uncinariasis and 6.9% for Estrongiloidiasis was found. Also, during 1999-2002, a serial coproparasitologic retrospective study was conducted; the population target was children younger than 6 years old with social security; the 60.5% of them were parasited. A 1.7% case of Uncinariasis and Estrongiloidiasis were found for each one. When comparing the case frequency of "children younger than 6 years old" sample from the prevalence study against "Children with social security which belongs to the free annual control program 2002" sample, a decrease of 39.6% cases was detected. In this last group, the 24.8% also had anemia, being the parasites found the major cause.
