Coprological examinations were made in 358 foreigners, 51 of which (14.2%) were positive from the point of view of hookworm eggs presence. On the basis of the discovered infection prevalence, which is still high in foreigners arriving to the CSSR from the tropics and subtropics and on the basis of the new information about the developmental cycle of Ancylostoma duodenale the author recommends to alter the so far valid antiepidemic measures in the following sense: Persons should be regarded as parasitologically negative to hookworm infection, if their coprological examination is permanently negative within 40 weeks of their stay in the CSSR.
对358名外国人进行了粪便检查，其中51人（14.2%）从钩虫卵存在的角度来看呈阳性。基于从热带和亚热带抵达捷克斯洛伐克社会主义共和国的外国人中发现的感染率仍然很高，以及基于十二指肠钩虫发育周期的新信息，作者建议在以下方面改变迄今有效的防疫措施：如果在捷克斯洛伐克社会主义共和国停留40周内粪便检查一直呈阴性，则应将这些人视为钩虫感染的寄生虫学阴性者。
