By performing the county-wide surveys of Paragonimus westermani infection in several areas in the Chilgok county, Kyungpook Province, three endemic foci of Paragonimus westermani were found. The foci found in this survey were Haksan first dong, Haksan second dong, and Settom in Kumhwa village, all in Kasan myun, Chilgok county. In the three communities, the positive rates for the fluke among the residents by the intradermal test with Paragonimus antigen varied from 22.3 per cent to 25.0 per cent; school children from these areas showed infection rates above 50 per cent. The rate in males and females was 23.9 and 23.0 per cent, respectively. This difference was not significant. The presence and number of Semisulcospira snails and Astacus crayfish, the intermediate hosts of Paragonimus westermani in the stream communities and the high infection rates for the fluke in the residents were the supporting factors in determining the foci.
通过对庆尚北道漆谷郡几个地区进行全县范围的卫氏并殖吸虫感染调查，发现了3个卫氏并殖吸虫地方性疫源地。本次调查发现的疫源地分别是漆谷郡加山洞的鹤山1洞、鹤山2洞以及锦和村的雪屯，均位于加山洞。在这3个社区中，用卫氏并殖吸虫抗原进行皮内试验，居民中吸虫的阳性率在22.3%至25.0%之间；这些地区的学童感染率超过50%。男性和女性的感染率分别为23.9%和23.0%。这种差异不显著。溪流群落中卫氏并殖吸虫中间宿主拟钉螺和螯虾的存在及数量，以及居民中吸虫的高感染率是确定疫源地的支持因素。
