1997年彰化秀傳紀念醫院受檢外籍勞工腸內寄生蟲感染調查研究
A Survey on Parasitic Infections among Foreign Laborers Examined in the Show-Chwan Memorial Hospital at Changhua in 1997
摘要
針對50611名於民國86年期間在秀傳紀念醫院體檢之外籍勞工腸內寄生蟲的感染情形做一統計分析，利用張氏糞便檢查收集器收集糞便檢體，並採用修飾性福馬林－乙醚法濃縮集卵，經硫汞－碘－蟻醛染色後以顯微鏡鏡檢。結果顯示有1850名外籍勞工感染，總陽性率為3.66%。共發現22種腸內寄生蟲，發現車最高者為鉤蟲，佔總受檢數之1.67%；其他為鞭蟲0.51%、微小阿米巴0.04%、大腸阿米巴0.34%、梨形鞭毛蟲0.32%、泰國肝吸蟲0.29%、蛔蟲0.07%、糞小桿線蟲0.04%、短小包膜絛蟲0.03%、痢疾阿米巴0.02%、布氏薑片蟲0.01%、棘口吸蟲0.01%、絛蟲0.01%、以及其他發現率小於0.01%的寄生蟲，包括嗜碘阿米巴、哈門氏阿米巴、豬－人肉孢子蟲、人芽囊原蟲、蟯蟲、菲律賓毛線蟲、東方毛圓線蟲、肝毛線蟲、以及曼氏血吸蟲。所有受檢呈陽性的檢體中，4.05%為多重感染者。進一步分析86年10月至12月期間受檢之外勞感染情形，各種不同國籍之腸道寄生蟲感染率，分別為泰國籍3.07%、印尼籍4.82%、以及菲律賓籍4.12%。複檢(3.57%)比新入境檢(3.09%)之外籍勞工感染率高。上述結果顯示外籍勞工腸道寄生蟲的感染率偏高，對於如何避免境外寄生蟲引入臺灣，落實檢疫工作，提昇檢驗品質乃為當務之急。

This study is conducted to determine the incidence of intestinal parasite infection in foreign laborers examined in Show-Chwan Memorial Hospital during an one year period (1997). Of 50,611 laborers examined by the modified formaline-ether concentration and the metrthiolate-iodine-formaline (MIF) stain methods, 1850 (3.66%) of those workers were positive, and 22 kinds of parasites were identified. Among those 1850 persons with intestinal parasites, hookworm was the most prevalent (1.67%), followed by trichuris trichiura (0.51%), Endolimax nana (0.44%), Entamoeba coli (0.34%), Giardia lamblia (0.32%), Opisthorchis uiuerrini (0.29%), Ascaris lumbricoides (0.07%), Strongyloides stercoralis (0.04%), Hymenolepis nana (0.03%), Entamoeba histolytica (0.02%), Fasciolopsis buski (0.01%), echinostomes (0.01%), Taenia sp. (0.01%), and others whose infectious rate was less than 0.01% including of Iodamoeba buetschlii, Entamoeba hartmanni, Sarcoeystis suihominis, Blastocystis hominis, Enterobius uermicularis, Capillaria Philippinensis, Trichostrongylus orienlalis, Capillaria hepatica, and Schislosoma mansoni. Four percent of those 1850 infected persons were infected with multiple parasites. Based on 13804 specimens examined during a period of three months (October to December, 1997), the infectious rates of laborer from Thailand, Indonesia, and the Philippines were 3.07%, 4.82%, and 4.12% respectively. The infectious rate of re-examined foreign laborers (3.57%) was higher than the first time examined foreign laborers (3.09%). Our results revealed that parasitic infections were prevalent among foreign laborers, and it is important to improve the quality of the parasitic test in order to prevent the introduction of these parasites to the native Taiwan populations.
