Abstract

Background and objectives: Cryptosporidium spp. is a major cause of gastrointestinal illness in humans. There are no data available on geospatial distribution of Cryptosporidium spp. in the Mazandaran Province, Iran. Therefore, the aim of this study was to determine the spatial patterns and demographic factors associated with Cryptosporidium spp. infection in the Mazandaran Province, North of Iran. Methods: Fecal specimens were collected from diarrheic individuals (n=215) who were referred to health centers in the Mazandaran Province during 2014-2015. The specimens were examined for presence of Cryptosporidium spp. oocysts by Ziehl-Neelsen acid-fast staining. Results: Cities of Sari, Neka, Noshahr and Behshahr were identified as disease hotspots. The prevalence of Cryptosporidium infection was significantly higher in subjects under 10 years of age as well as those living in low-altitude areas and rural areas without access to standard water sources. Conclusion: Our findings and the GIS-derived data could be used to facilitate cryptosporidiosis surveillance and monitoring of Cryptosporidium spp. distribution in the study area.

利用地理信息系统评价伊朗北部马赞达兰省腹泻人群隐孢子虫的空间分布和流行病学

背景与目的:隐孢子虫是人类胃肠道疾病的主要病因。伊朗马赞达兰省隐孢子虫的地理空间分布尚无资料。因此，本研究的目的是确定伊朗北部马赞达兰省隐孢子虫感染的空间格局和人口统计学因素。方法:收集2014-2015年在马赞达兰省卫生中心转诊的腹泻患者(n=215)的粪便标本。Ziehl-Neelsen抗酸染色检测隐孢子虫卵囊的存在。结果:萨里市、内卡市、诺沙赫尔市和贝沙赫尔市被确定为疾病热点。隐孢子虫感染率在10岁以下人群、低海拔地区和农村无标准水源人群中较高。结论:本研究结果和gis数据可用于研究区隐孢子虫病监测和隐孢子虫分布监测。
