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.
To determine the prevalence of intestinal parasites in street dwellers attending a shelter in Cali, Colombia.
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.
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.
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.
肠道寄生虫感染是一个公共卫生问题，特别是在弱势群体中。关于街头居民肠道寄生虫感染的患病率和决定因素的研究较少，而这些人可能会经历重大的健康和社会经济问题。了解这一人群中肠道寄生虫的患病率和相关因素对于针对这些感染采取干预措施以减轻其传播至关重要。
确定在哥伦比亚卡利的一个收容所中居住的街头居民中肠道寄生虫的患病率。
我们选择了符合纳入标准的 66 名参与者。我们收集了连续的粪便样本进行实验室评估以及社会人口学数据，并收集了有关他们的卫生习惯和成瘾情况的信息。
76%的参与者有肠道寄生虫或共生菌，30%存在单虫感染，46%存在多虫感染，20%存在嗜酸性粒细胞增多症。类布氏隐孢子虫是最常见的病原体（68.18%），其次是内阿米巴（34.85%）和结肠内阿米巴（18.18%）。最常见的病原体是溶组织内阿米巴/迪斯帕内阿米巴/莫氏内阿米巴复合体（10.61%）和钩虫（9.09%）。我们评估了与患病率相关的决定因素。
肠道寄生虫感染是卡利街头居民的一个健康问题。建议进行连续检查以诊断肠道寄生虫感染，特别是在寄生虫负荷较低的情况下。应开展运动以降低易发生并发症人群中这些寄生虫的患病率。
