调查了韩国玉川郡金江沿着华支睾吸虫病和后殖吸虫病的流行状况。从2000年2月至12月，对5个村庄的1 081名居民的粪便进行了检查。每个粪便标本检查的玻璃纸厚涂片法和福尔马林乙醚沉降技术。虫卵阳性病例采用Stoll虫卵计数法进一步分析，阳性病例给予吡喹酮治疗。华支睾吸虫和后殖吸虫虫卵阳性率分别为9.3%和5.5%，双重感染率为3.5%。每克粪便虫卵数（EPG）为1.54 × 10 - 5;中华按蚊918 ± 1,463，后殖吸虫711 ± 947。C.滨江区中华按蚊和后殖吸虫的检出率分别为14.2%和8.4%，显著高于内陆区的3.2%和1.7%。C.中华绒螯蟹和后殖吸虫的阳性率分别为16.7%和10.0%，显著高于雌蟹（3.5%和1.8%）。不同地区、不同性别间EPG值差异不显著。华支睾吸虫病和后殖吸虫病的患病率明显低于以往报告。然而，C.中华绒螯蟹（Metagonimus sinensis）和后殖吸虫（Metagonimus sp.）
The endemic status of clonorchiasis and metagonimiasis along the Geum-gang (River) in Okcheon-gun (County) in Korea was examined. From February to December 2000, stools of total 1,081 inhabitants living in 5 villages were examined. Each stool specimen was examined by both the cellophane thick smear method and the formalin-ether sedimentation technique. Egg-positive cases were further analyzed by Stoll's egg-counting technique, and praziquantel was administered to positive cases. The egg-positive rates for Clonorchis sinensis and Metagonimus species were 9.3% and 5.5%, respectively, and the double infection rate was 3.5%. The numbers of eggs per gram (EPG) of feces of C. sinensis and Metagonimus sp. were 918+-1,463 and 711+-947, respectively. The egg-positive rates for C. sinensis and Metagonimus sp. in the riverside area were 14.2% and 8.4%, respectively, which were significantly higher than those of the inland area (3.2% and 1.7%, respectively). The egg-positive rates of C. sinensis and Metagonimus sp. in males (16.7% and 10.0%) were significantly higher than those of females (3.5% and 1.8%). However, there were no significant differences of EPG values between localities and sexes. The prevalence of clonorchiasis and metagonimiasis in this survey was significantly lower than that in the previous reports. However, there is still a high prevalence of infection with C. sinensis and Metagonimus sp. in this region, especially in the riverside area.
