蛔虫病

由于蛔虫病和其他土源性蠕虫病在许多发展中地区有高的发病率，建议对来自这些地区的移民、国际被收养者和某些返回的旅行者进行筛查。

收养

发现高达 60% 的国际被收养儿童有传染病。美国儿科学会建议检查儿童粪便中的虫卵和寄生虫，作为对该类儿童进行传染病筛查的一部分。[33]American Academy of Pediatrics. Medical evaluation of internationally adopted children for infectious diseases.

旅行者

那些从疫区旅行归来的旅行者，应当通过检查粪便虫卵和寄生虫，筛查其是否有蛔虫病和其他的肠道寄生虫。[34]Centers for Disease Control and Prevention. Pre- and post-travel general health recommendations. In: Health information for international travel 2008. Atlanta, GA: US Department of Health and Human Services, Public Health Service; 2007.
