[Investigation on the parasites of alien laborers in Kaohsiung].
In the past year, stool specimens of 1,732 alien laborers were examined for intestinal parasites. There was no significant difference in the positive rate between males and females. All alien laborers were examined in 3 hospitals and the positive rates were 24.8% (191/769), 13.6% (109/804) and 12.6% (20/159). Broken down by nationality, the positive rates in laborers from Thailand, Indonesia, the Philippines and Malaysia were 23.9% (192/803), 20.3% (62/305), 12.1% (60/498) and 4.8% (6/126) respectively. Of all alien laborers, 17.2% (297/1,732) had single infections of parasites and 1.3% (23/1,732) had multiple infections. Opisthorchis viverrinii was the most prevalent parasite found in infected alien laborers. 91.5% of alien laborers were aged from 21 to 40-years-old and had positive rates of parasites reaching 91.0%. The time of arrival in Taiwan had an effect in all alien laborers examined for parasites. The positive rate in laborers arriving during April to June was 22.7% which was significantly higher than the 16.3% for laborers arriving in other months.
