Prevalence of intestinal parasites in street dwellers attending a shelter in Cali, Colombia

Abstract

Introduction. Intestinal parasitic infections represent a public health problem, especially among vulnerable populations. There are few studies on the prevalence and determinants of intestinal parasites infections in street dwellers, who may experience significant health and socioeconomic implications. Understanding the prevalence and associated factors of intestinal parasites in this population is crucial for targeted interventions to mitigate the spread of these infections.Objective. To determine the prevalence of intestinal parasites in street dwellers attending a shelter in Cali, Colombia.Materials and methods. We selected 66 participants who met the inclusion criteria. We collected serial stool samples for laboratory evaluation and sociodemographic data, and information on their hygiene habits and addictions.Results. Seventy-six percent of the participants had intestinal parasites or commensals, with 30% presenting monoparasitism, 46% polyparasitism, and 20% eosinophilia. Blastocystis spp. was the most common organism (68.18%), followed by Endolimax nana (34.85%) and Entamoeba coli (18.18%). The most common pathogens were the Entamoeba histolytica/E. dispar/E. moshkovskii complex (10.61%) and hookworms (9.09%). We evaluated prevalence-related determinants.Conclusions. Intestinal parasitism is a health problem among street dwellers in Cali. A serial examination is recommended for diagnosing intestinal parasitic infection, especially in cases of low parasite loads. Campaigns should be established to reduce the prevalence of these parasites in populations at risk of complications.
