摘要

Background: Although the present prevalence of filariasis in the Thai population is low, migration of Myanmar labor into Thailand may increase the incidence of bancroftian filariasis. Due to the previous report, the prevalence of filariasis in Myanmar-migrant workers was very high. In this study, we reported the prevalence of lymphatic filariasis in Myanmar-migrant workers in Bangsaparn district, Prachuab Kiri Khan, a rural community in the Southern Region of Thailand with the high density of Myanmar-migrant workers as fishermen. Methods: We analyzed the data of screening for filariasis using microscopic examination among 250 Myanmar-migrant workers (169 males and 81 females) who had just stayed in Thailand for less than 1 month. Results: The microfilarial rate among these Myanmar migrants was 2.4 %. All cases were bancroftian filariasis. The microfilarial rates in males and females were 3.0% and 1.2 %, respectively. Conclusion: Since these migrants carry the parasite with high infected rate and the mosquito vector Culex quinquefasciatus is also prevalent in Thailand, Thai people are at high risk of acquiring this disease if good control and prevention strategies are not implemented. Filaria screening test as one of the infection control strategies is necessary. Presented at the Joint International Tropical Medicine Meeting 2001 Bangkok Thailand August 8 - 10, 2001 Introduction Lymphatic filariasis, caused by filarial nematode parasites, is an important mosquito-borne disease in the tropical countries including to Thailand. Up to billion of people around the world is the population at risk for filariasis (1). The two species as Wuchereria bancrofti and Brugia malayi are the two common pathogenic parasites in Thailand (2, 3). Presently, in Thailand, endemic areas of lymphatic filariasis are limited to some provinces in the Western, Southern and Northern region (3). However, due to the recent report of Triteeraprapab and Songtrus (4), the high prevalence as up to 4.4 % was reported in the group of Myanmar migrant workers in Tak province,Northern Region of Thailand. Such a high infection rate obviously deserve Thai public health concern, therefore, specific infectious control program for communicable diseases among the migrant Myanmar workers was purposed.Recently, more than thousands of Myanmar workers live in Thailand, working as the laborers. Furthermore, though most of these workers are legal some are illegal. Also, these workers are usually a carrier of many diseases, therefore, the outbreak of some controllable diseases in Thailand can be expected (4). Here, we reported the result of screening tests for the Myanmar migrant workers in a rural district near Thai-Myanmar border, where a number of Myanmar immigrated for better job and income. Materials and Methods Study setting and populationThe setting of this study is at Bangsaparn District, Prachuab kiri khan Province, about 400 km from Bangkok capital city. This district is a rural district closed to Thai Gulf. Also, Thai-Myanmar border locates in this area. There are hundreds of Myanmar immigrate to this district to work as fishermen. According to the communicable diseases control program, the screening program for all migrant workers was set by the district hospital. The data from two hundreds and fifty Myanmar workers who had just stayed in Thailand for less than 1 month and passed the screening program by the district hospital during year 1997 were reviewed in this study.Screening for filariasisAll screenings in this study were performed by the medical technologists. The method use for diagnosis of filaria in this study was identification of microfilaria in the peripheral blood smear as described in the previous study (4). All subjects were got blood collection during 9.00 - 11.00 o'clock. Thin and think blood films were prepared for each individual. All blood films were examined under the light microscope ( X 1,000).Data analysisReview of all recorded data was performe
