This paper reports the prevalence of helminthiasis among Myanmar migrants in the municipality of Mae Sot, Tak Province, 2008. The sample was randomly selected by using the 30-cluster sampling technique. Fecal samples were examined for parasitic eggs using the Kato-Katz thick smear technique. Frequency and percentage were used to present the results of analysis. The chi-square test was used for comparison between factors and helminthiasis and multiple logistic regression analysis was used to determine factors associated with infection. Of the 1,751 migrants examined, 475 (27.1%) had at least one helminth. The highest prevalence of helminthiasis was among migrants 15-24 years old (34.7%), followed by those 5-14 years of age (31.1%). The prevalence of infection slightly decreased with higher educational levels. Students and factory workers had lower prevalence rates than others. Migrants registered for work permits had a lower rate than those who were not. The most common helminth identified was Trichuris trichiura (18.0%), followed by Ascaris lumbricoides (8.8%) and hookworm (4.0%). A decrease in prevalence of infection was associated with increasing age, being a factory worker and being registered for work permits. This study indicates that yearly provision of a broad spectrum anti-helminthic drug to all migrants registered for work permits is effective and should also cover those who are not registered.
