本报告总结了一项前瞻性研究腹泻队列农村儿童在其自然生态系统，和一个纵向研究的腹泻城市儿童参加医院急诊服务。4.3%的病例粪便中发现隐孢子虫卵囊，而所有对照均为阴性。农村婴儿1岁内没有感染，而大都市地区1岁以下儿童的感染率为3%。这可能是由于农村地区几个月的密集和纯母乳喂养，而在城市地区，许多婴儿根本不母乳喂养，或过早断奶。在全母乳喂养的婴儿中没有发现感染。与隐孢子虫相关的腹泻是水样的，没有炎性细胞。脱水在城市儿童中很常见，但通过口服补液治疗或在某些情况下通过静脉输液治疗迅速纠正。感染集中在一年中温暖、多雨和潮湿的月份。
This report summarizes both a prospective study of diarrhea in cohorts of rural children in their natural ecosystem, and a vertical study of diarrheic urban children attending a hospital emergency service. Cryptosporidium oocysts were found in feces of 4.3% of the cases, while all controls were negative. No infection occurred in the 1st yr of life among rural infants, contrasting with a 3% infection rate in children under 1 yr of age in the metropolitan area. This could be attributed to intense and exclusive breastfeeding for several months in the rural area while in the urban area many infants are not breat-fed at all, or are weaned prematurely. No infection was found in wholly breast-fed infants. Diarrhea associated with Cryptosporidium was watery and without inflammatory cells. Dehydration was common in urban children, but was rapidly corrected by oral rehydration therapy, or by i.v. fluid therapy in some cases. Infections clustered in the warmer, rainy and humid months of the year.
