项目摘要

In the course of study for 3 years, a total of 6 surveys, 3 for illegal immigrants in a detention camp in Negeri Sembilan and 3 for legal foreign workers in a plantation estate in Selangor, was carried out. A total of 741 study subjects consisted of 308 illegal immigrants, 221 legal foreign workers and 212 local workers as control. Indonesians were dominated among the illegal immigrants followed by those from other Asian countries. Most of the legal foreign workers were Indonesian.As a whole, prevalence of parasitic infections was higher in illegal immigrants, particularly for pathogenic protozoa and ectoparasites, reflecting lower hygienic standard of their living condition. The legal Indonesian workers were found to have a relatively high prevalence of asymptomatic malaria, which may have been acquired when they went on a home visit in Indonesia. The local workers showed different features of parasitic infections according to their ethnicity. Country of origin appeared to have an influence on the status of parasitic infections.Our attempts to identify non-endemic infections did not detect any positive cases among the foreigners. However, many infections could have been brought by migrant workers, both legal and illegal, from their country of origin. Thus the migrants with these infections certainly will play an important role in sustaining the infections at a certain level in Malaysia. The legal migrants enjoy the freedom of movement within the host country, and this provides ample opportunities for the spread of new diseases. For the imported parasitoses, health check at entrance of immigrants could have an important role to prevent spreading out the infections into the country, although it is impossible for the illegal immigrants.

在研究过程中，进行了3年的研究，总共进行了6次调查，在尼格利·塞姆比兰（Negeri Sembilan）的一个拘留营中为非法移民进行了3次调查，在雪兰莪（Selangor）的一家种植园中为法律外国工人进行了3次调查。共有741名研究对象包括308名非法移民，221名合法的外国工人和212名当地工人作为控制。印尼人在非法移民中受到了统治，随后是来自其他亚洲国家的人。大多数合法的外国工人都是印度尼西亚人。整个非法移民的寄生虫感染率更高，特别是对于致病性原生动物和骨质寄生虫，反映了其生活状况的较低卫生标准。发现法律印度尼西亚工人的无症状疟疾患病率相对较高，这可能是在印度尼西亚进行家庭访问时获得的。当地工人根据寄生虫的种族展示了寄生虫感染的不同特征。原籍国似乎对寄生虫感染的状况有影响。我们的识别非流行感染的尝试并未发现外国人之间的任何积极病例。但是，从其原籍国的法律和非法工人都可能引起许多感染。因此，具有这些感染的移民肯定会在马来西亚的一定水平维持感染中发挥重要作用。法定移民享有东道国内部运动的自由，这为传播新疾病提供了充足的机会。对于进口的寄生虫，尽管非法移民是不可能的，但移民入口处的健康检查可能会发挥重要作用，以防止向该国传播感染。
