Nishimura in 1943 indicated for the first time that a serious endemic focus of Clonorchis sinensis is located in the vicinity of Yeong-cheon(Kyungpook Province, Korea). Later, numerous surveys of this fluke in the Province have been made, but no additional report on the endemic focus of the fluke has been available. The overall percentage of Clonorchis sinensis infections, based on the discovery of eggs by the formalin-ether sedimentation technique, was found to be 54.8 percent from 851 residents in Nakjeon ri (village), Danmil myun, Uiseong gun (county), Kyungpook Province and no significant difference was observed in the sex specific rate of the individuals infected. There is a high incidence of infection with Clonorchis sinensis. The infection rate in the age group from 0 to 4 years was 14.6 per cent, 5 to 9 years was 35.7 per cent and 10 to 14 years was 51.7 per cent. In the worn burdens for residents, the average number of egg-counts was 41,800. It is found that a serious endemic focus of Clonorchis sinensis exists in the vicinity of Nakjeon village.
西村于1943年首次指出，华支睾吸虫的一个严重地方性疫源地位于永川（韩国庆尚北道）附近。后来，对该省的这种吸虫进行了大量调查，但尚未有关于该吸虫地方性疫源地的其他报告。基于福尔马林 - 乙醚沉淀技术发现虫卵，庆尚北道醴泉郡丹密面纳川里（村）851名居民中华支睾吸虫感染的总体百分比为54.8%，且在感染个体的性别特异性率上未观察到显著差异。华支睾吸虫感染率很高。0至4岁年龄组的感染率为14.6%，5至9岁为35.7%，10至14岁为51.7%。在居民的虫负荷方面，虫卵计数的平均数为41,800。发现纳川村附近存在华支睾吸虫的一个严重地方性疫源地。
