A large number of foreign laborers are now working in Taiwan, the majority coming from Southeast Asia where parasitic infections are common. Since 1992, monitoring the intestinal parasitic infections of these foreigners has been carried out, particularly to prevent the introduction of some of the parasites into Taiwan. This paper reports results obtained during the year 1993-1994.
The merthiolate-iodine-formalin (MIF) concentration method was used to detect intestinal parasites; and the data were analyzed by chi 2-test.
Among the 3,020 persons examined, 526 (17.4%) were infected and 14 kinds of parasites were identified; i.e. Ascaris lumbricoides, Trichuris trichiura, Strongyloides stercoralis, Enterobius vermicularis, hookworms, Taenia sp., Opisthorchis viverrini, Fasciolopsis buski, Schistosoma japonicum, an echinostome, Entamoeba histolytica. Entamoeba coli, Endolimax nana and Giardia lamblia. By nationality, those workers from Indonesia had the highest infection rate, at 32.3%; they were followed by the Filipinos (18.7%), the Thais (16.6%) and the Malaysians (8.0%). The three or four most prevalent parasites were T. Trichiura (21.8%), A. lumbricoides (5.6%) and hookworms (2.4%) for the Indonesians; T. Trichiura (9.1%), A. lumbricoides (3.7%), hookworms and E. histolytica (2.1% each) for the Filipinos; O. viverrini (8.4%), hookworms (3.3%) and E. histolytica (1.2%) for the Thais; T. trichiura (2.2%), A. lumbricoides and E. histolytica (1.8% each) and hookworms (1.4%) for the Malaysians. Among the 526 persons infected, 92.2% had 1 species, 7.2% had 2 species, 0.4% had 3 species and 0.2% had 4 species of parasites.
The present result, a 17.4% infection rate, was significantly higher (p < 0.05) than the 12.3% obtained for the previous year (1992-1993). E. histolytica was found in 34 persons, 16 of whom were working as live-in housemaids. The epidemiological significance of some parasites is discussed here.
目前有大量外籍劳工在台湾工作，其中大多数来自寄生虫感染常见的东南亚地区。自1992年以来，一直在对这些外籍人员的肠道寄生虫感染情况进行监测，特别是为了防止某些寄生虫传入台湾。本文报告了1993 - 1994年期间获得的结果。
采用硫柳汞 - 碘 - 福尔马林（MIF）浓缩法检测肠道寄生虫；并通过卡方检验对数据进行分析。
在接受检查的3020人中，526人（17.4%）被感染，共鉴定出14种寄生虫，即蛔虫、鞭虫、粪类圆线虫、蛲虫、钩虫、带绦虫、华支睾吸虫、姜片吸虫、日本血吸虫、一种棘口吸虫、溶组织内阿米巴、结肠内阿米巴、微小内蜒阿米巴和蓝氏贾第鞭毛虫。按国籍划分，来自印度尼西亚的劳工感染率最高，为32.3%；其次是菲律宾人（18.7%）、泰国人（16.6%）和马来西亚人（8.0%）。印度尼西亚人最常见的三四位寄生虫是鞭虫（21.8%）、蛔虫（5.6%）和钩虫（2.4%）；菲律宾人是鞭虫（9.1%）、蛔虫（3.7%）、钩虫和溶组织内阿米巴（各2.1%）；泰国人是华支睾吸虫（8.4%）、钩虫（3.3%）和溶组织内阿米巴（1.2%）；马来西亚人是鞭虫（2.2%）、蛔虫和溶组织内阿米巴（各1.8%）以及钩虫（1.4%）。在526名感染者中，92.2%感染1种寄生虫，7.2%感染2种，0.4%感染3种，0.2%感染4种寄生虫。
目前17.4%的感染率结果显著高于上一年（1992 - 1993年）的12.3%（p < 0.05）。在34人身上发现了溶组织内阿米巴，其中16人是住家女佣。本文讨论了一些寄生虫的流行病学意义。
