In Costa Rica there were three national surveys of intestinal parasitism (1966, 1982, and 1996) that showed dramatic reduction of the prevalence of Trichuris, Ascaris, and Necator/Ancylostoma (hookworms); however, these nematodes persist with high prevalence in low socio-economically groups, as the squatter settlements around the cities; however, it is possible that pour Amerindian communities with substandard housing condition also suffer the burden of intestinal parasites. For this reason, the present study was planted in a rural disperse Amerindian community from the South of Costa Rica. 45 fecal samples were collected from children under 15 years old, and were processed according a modification of the Baermann method, which also permits the observation of other parasites beyond Strongyloides. 38 (84%) of the analyzed samples were positive for at least one parasite. The prevalence for nematodes was Ascaris (36%), hookworms (22%) Enterobius (4%), and Trichuris (2%). For protozoa was Endolimax nana (33%), Entamoeba coli (27%), and Entamoeba histolytica/dispar (11%). These data are the reflect of the inadequate sanitation conditions of this community
