Abstract (English):	According to the World Health Organization (WHO), intestinal parasitosis occurs mainly in underdeveloped countries, with a greater impact on school-age children. They are closely related to poverty and the most disadvantaged social groups. The aim of this study was to determine the prevalence of intestinal parasites in children from poor neighborhoods in the Central Department of Paraguay in 2023 and 2024. Observational, descriptive, cross-sectional, non-probabilistic convenience sampling study, reaching a total of 167 children in the neighborhoods ¨San Francisco¨ from Asunción and ¨San Blas¨ from Mariano Roque Alonso. Direct observation of fresh stool material, the modified Ritchie technique and the spontaneous sedimentation technique were used. From the coproparasitological analysis, 69 samples (41%) were positive for intestinal parasite findings, 25 of them (36%) were pathogenic parasites and 44 (64%) were commensal parasites. Giardia lamblia (30%) and Blastocystis hominis (27.5%) were the most prevalent. The data obtained show a lower prevalence of intestinal parasitosis in comparison with previous data from other studies carried out at national level, nevertheless we cannot assert a decrease in the prevalence of intestinal parasitosis in the child population, due the absence of prevalence studies from previous years in the same population. National statistics are needed to evaluate an improvement in health conditions such as access to drinking water, as well as the effectiveness of deworming campaigns promoted by an institutional entity.

Abstract (Spanish):	Según la Organización Mundial de la Salud (OMS) las parasitosis intestinales se presentan principalmente en países subdesarrollados, con un mayor impacto en los niños en edad escolar. Están estrechamente relacionadas con la pobreza y los grupos sociales más desamparados. El objetivo del presente trabajo consistió en determinar la prevalencia de parásitos intestinales en la población infantil de barrios carenciados del departamento Central del Paraguay en el 2023 y 2024. Estudio observacional, descriptivo, de corte transversal, muestreo no probabilístico por conveniencia, alcanzando un total de 167 niños en los barrios San Francisco de Asunción y San Blas de Mariano Roque Alonso. Se realizó observación directa del material fresco de las heces, la técnica de Ritchie modificada y la técnica de sedimentación espontánea. Del análisis coproparasitológico, 69 muestras (41%) dieron positivas a hallazgos de parásitos intestinales, 25 de ellas (36%) fueron parásitos patógenos y 44 (64%) comensales. Giardia lamblia con el 30% y Blastocystis hominis con el 27,5% fueron los más prevalentes. Los datos obtenidos exponen una menor prevalencia de parasitosis intestinal en comparación con datos anteriores de otros estudios realizados a nivel nacional, pese a lo cual no podemos aseverar la existencia de una disminución de ésta en la población infantil, a falta de estudios de prevalencia de años anteriores en la misma población. Se precisan estadísticas nacionales para evaluar una mejoría en las condiciones de salubridad como el acceso a agua potable, así como la efectividad de las campañas de desparasitación impulsadas desde el ente institucional.
