Giardia and Cryptosporidium are protozoan parasites that can cause prolonged gastrointestinal infection especially in immunocompromised individuals. We studied the characteristics of giardiasis and cryptosporidiosis cases notified to the Finnish Infectious Disease Registry (FIDR) during 1995-2006, and of persons tested for these parasites in the clinical laboratory of the healthcare district of Helsinki and Uusimaa during 2004-2006. According to reporting, the incidence of both infections was higher in persons residing in the Helsinki area than in other parts of Finland. Persons born abroad were more often tested than were persons born in Finland, and the proportion of the Giardia infected among those tested was very high (14%) in children under the age of five born abroad. Giardia was tested for over 70 times as often as Cryptosporidium, which thus appears to be heavily under tested and therefore underdetected.
贾第虫病和隐孢子虫病是原生动物寄生虫病，可导致免疫功能低下者的胃肠道感染迁延不愈。我们研究了芬兰传染病监测系统（FIDR）于 1995-2006 年通报的贾第虫病和隐孢子虫病病例的特征，以及赫尔辛基和乌西玛地区医疗服务区临床实验室于 2004-2006 年检测这些寄生虫的患者的特征。根据报告，在赫尔辛基地区居住的人群中，这两种感染的发病率均高于芬兰其他地区。与芬兰出生者相比，出生于国外者接受的检测更多，在国外出生的五岁以下儿童中，贾第虫感染者的比例非常高（14%）。检测贾第虫的次数比检测隐孢子虫多 70 多倍，这表明隐孢子虫检测严重不足，因此漏检率很高。
