The epidemiologic features of Strongyloides stercoralis infection in Kentucky were studied by an analysis of clinical cases at the University of Kentucky Medical Center (UKMC); by an analysis of parasitologic records of the Kentucky Bureau for Health Services (KBHS); and by a prospective stool survey of school children in Clay County, located in southeastern Kentucky, an area of the state previously found to be highly endemic for intestinal parasites. S. stercoralis was the most common parasitic infection diagnosed at UKMC. The patients were predominantly white male adults who were over 50 years old, had an associated chronic or debilitating medical illness, were of low socioeconomic background, and resided in southeastern Kentucky. S. stercoralis was a common parasitic infection at KBHS ad the patients showed a similar geographic distribution. Of 561 Clay County children surveyed, 23.7% harbored one or more intestinal parasite pathogens and 3.0% had S. stercoralis. Thus, S. stercoralis remains highly endemic in Kentucky and may cause disease even in geriatric patients.
通过分析肯塔基大学医学中心（UKMC）的临床病例、肯塔基州卫生服务局（KBHS）的寄生虫学记录，以及对肯塔基州东南部克莱县学童进行前瞻性粪便调查，研究了粪类圆线虫感染在肯塔基州的流行病学特征。克莱县是该州此前发现肠道寄生虫高度流行的地区。粪类圆线虫是UKMC诊断出的最常见寄生虫感染。患者主要是50岁以上的白人成年男性，伴有慢性或使人衰弱的疾病，社会经济背景较低，居住在肯塔基州东南部。粪类圆线虫在KBHS是一种常见的寄生虫感染，患者呈现相似的地理分布。在接受调查的561名克莱县儿童中，23.7%携带一种或多种肠道寄生虫病原体，3.0%感染了粪类圆线虫。因此，粪类圆线虫在肯塔基州仍然高度流行，甚至可能在老年患者中引发疾病。
