Parasitological examination of the population of the Amur Region has revealed that the nanophyetiasis foci affecting as high as 28.4% of the people are being preserved and functioning now; at the same time the highest rates of infection with the trematode Nanophyetus salmincola schikhobalowi are seen in the dwellers of the populated areas situated on the banks of the mountain Amur tributaries. It has been ascertained that the major season when the population is infected with Nanophyetus is summer and its highest incidence are noted in autumn (November) after the active fishing season is completed. It has been found that infection occurs in infants and the maximum incidence is in the age group of 21-30 years (45.5%) and remains virtually the same in a middle-aged population [31-50 years (37.0-42.2%)], by decreasing slightly in the older age groups (18.2-21.7%). According to the questionnaire survey data, fish (90% of its species are an intermediate host for Nanophyetus) is a staple food in the population of the highest incidence rural areas. The major causes of Nanophyetus infection are the wide consumption of raw and low-salt fish and a low population awareness of measures to prevent helminthiasis, the transmission factor of which is fish.
对阿穆尔地区居民的寄生虫学检查发现，目前影响高达28.4%人口的阔节裂头绦虫病疫源地仍然存在且在发挥作用；与此同时，在阿穆尔河山区支流沿岸聚居区的居民中，感染吸虫鲑居尾孢绦虫的比例最高。已确定居民感染阔节裂头绦虫的主要季节是夏季，在秋季（11月）捕鱼旺季结束后发病率最高。研究发现，婴儿也会感染，发病率最高的年龄组为21至30岁（45.5%），中年人群（31至50岁，发病率为37.0%至42.2%）的发病率基本相同，而在老年人群中发病率略有下降（18.2%至21.7%）。根据问卷调查数据，在发病率最高的农村地区，鱼类（其90%的种类是阔节裂头绦虫的中间宿主）是主要食物。感染阔节裂头绦虫的主要原因是大量食用生鱼和低盐鱼，以及居民对预防蠕虫病措施的认识不足，而蠕虫病的传播媒介就是鱼类。
