The aim of this study was to reveal sources where cryptosporidiosis may be acquired. We studied 4545 patients, from whom 5730 stool samples were obtained for the diagnosis of parasitic infections during 13 mo, and found that 119 of these patients (2.62%) excreted oocysts of Cryptosporidium. About two-thirds of the patients reported no animal contacts. There were no cases among children under the age of 5 yr, which is evidence against endemicity, and the prevalence was highest (6.22%) in young adults aged 15-29 yr. The sex distribution was unremarkable: of the 119 patients, 56 were men and 63 were women. Most patients reported a recent trip abroad, which had taken place 12 times more frequently during the previous month than earlier. Cryptosporidiosis was five times more frequent in patients who had recently visited Leningrad than in others, and seven times more frequent in patients with Giardia lamblia than in others. Sporadic cryptosporidiosis occurs mainly in travelers, and seems to be acquired from similar sources as giardiasis.
本研究的目的是揭示可能感染隐孢子虫病的来源。我们对4545名患者进行了研究，在13个月期间从他们身上获取了5730份粪便样本用于诊断寄生虫感染，发现其中119名患者（2.62%）排出了隐孢子虫的卵囊。约三分之二的患者表示没有接触过动物。5岁以下儿童中无病例，这证明不存在地方流行性，患病率在15 - 29岁的年轻人中最高（6.22%）。性别分布无明显差异：119名患者中，56名男性，63名女性。大多数患者报告近期出过国，前一个月出国的频率比之前高出12倍。近期去过列宁格勒的患者感染隐孢子虫病的频率是其他人的5倍，感染蓝氏贾第鞭毛虫的患者感染隐孢子虫病的频率是其他人的7倍。散发性隐孢子虫病主要发生在旅行者中，似乎与贾第虫病有相似的感染源。
