Stool examination is a requirement of the screening program for Thai workers seeking overseas employment. We report on the prevalence of intestinal parasitic infections among these workers; the stool examination results of 2,213 Thai workers who visited the Out-patients Department of the King Chulalongkorn Memorial Hospital between September 2000 and January 2001 were analysed. One hundred and thirty-five (6.1%) were found to be infected with 1 or 2 species of parasite. There were 54 (40%), 47 (34.8%), and 25 (18.5%) cases infected with nematodes, platyhelminths and protozoa, respectively. The commonest parasite was Opisthorchis viverrini (28.9%). Most nematode infections were due to Strongyloides stercoralis (19.2%); most protozoal infections were due to Giardia lamblia (17.0%). Mixed infections were found in 9 cases. Not unexpectedly, the rate of intestinal parasitic infection among Thai workers remains high. Screening for the parasitic infections among these workers can help to decrease their rate of rejection by the countries in which overseas employment is sought.
粪便检查是泰国寻求海外就业工人筛查项目的一项要求。我们报告了这些工人肠道寄生虫感染的流行情况；分析了2000年9月至2001年1月期间到朱拉隆功国王纪念医院门诊部就诊的2213名泰国工人的粪便检查结果。发现135人（6.1%）感染了1种或2种寄生虫。分别有54例（40%）、47例（34.8%）和25例（18.5%）感染线虫、扁形虫和原生动物。最常见的寄生虫是华支睾吸虫（28.9%）。大多数线虫感染是由粪类圆线虫引起的（19.2%）；大多数原生动物感染是由蓝氏贾第鞭毛虫引起的（17.0%）。发现9例混合感染。不出所料，泰国工人肠道寄生虫感染率仍然很高。对这些工人进行寄生虫感染筛查有助于降低他们被寻求海外就业国家拒签的比例。
