A nationwide survey was performed to know the distribution and prevalence of human Gymnophalloides seoi infection on western and southern coastal islands in the Republic of Korea. A total of 4,178 fecal specimens were collected from residents on 45 (24 western and 21 southern) islands, and examined by Kato-Katz and formalin-ether sedimentation techniques. Eggs of G. seoi were detected from 160 (3.8%) people living on 22 (13 western and 9 southern) islands. The prevalence varied by the location of islands; higher on western islands than on southern islands. The highest prevalence was found on Amtaedo (25.3%), followed by Cheungdo (25.0%), and Anchwado (20.9%) (Shinan-gun). A little lower prevalence was observed on Munyodo (13.3%), Shinshido (12.9%), and Sonyudo (10.3%) (Kunsan-shi). Of the remaining islands, the regions showing the prevalence greater than 5% included Kohado, Dallido (Mokpo-shi), Pyeongildo, Kogumdo (Wando-gun), and Keogumdo (Kohung-gun). A strong age predilection was noted (p < 0.05); 95% of the infected people were over 40 years old. Females showed a little higher prevalence than males. The results indicate that human G. seoi infection is more widely distributed than previously considered. Nine of 11 islands (excluding the 2 known areas Munyodo and Sunyudo) that showed greater prevalence than 5% are regarded as new endemic foci of G. seoi.
为了解韩国西部和南部沿海岛屿上人体感染西氏裸茎吸虫的分布及流行情况，开展了一项全国性调查。从45个（24个西部和21个南部）岛屿的居民中总共收集了4178份粪便标本，并采用加藤-厚涂片法和福尔马林-乙醚沉淀技术进行检测。在22个（13个西部和9个南部）岛屿的160人（3.8%）粪便中检测到西氏裸茎吸虫虫卵。流行率因岛屿位置而异；西部岛屿高于南部岛屿。在岩泰岛（25.3%）发现的流行率最高，其次是长岛（25.0%）和安川岛（20.9%）（新安郡）。在文岛（13.3%）、新实岛（12.9%）和索尼岛（10.3%）（群山市）观察到的流行率略低。在其余岛屿中，流行率高于5%的地区包括古哈多岛、达利岛（木浦市）、平岛、古金岛（莞岛郡）和巨金岛（固城郡）。发现存在明显的年龄偏好（p<0.05）；95%的感染者年龄在40岁以上。女性的流行率略高于男性。结果表明，人体感染西氏裸茎吸虫的分布比之前认为的更为广泛。在11个流行率高于5%的岛屿中（不包括已知的文岛和索尼岛这2个地区），有9个被视为西氏裸茎吸虫的新流行疫源地。
