北安为黑龙江省克山病重点流行区之一,据流行病学调查初步资料指出该病具有明显地区性,而考虑病因可能存在于环境,怀疑为自然疫源性疾病。该地区毗邻草甸荒地,区中动物群落尤以(?)齿动物及其体外寄生物在该病流行季节出现高峰很值得重观。为了从自然疫源地学说探索(?)齿动物及其体外寄生腐食(?)与克山病流行学关系的线索,自1956年9月至1958
Bei’an is one of the key endemic areas for Keshan disease in Heilongjiang Province. According to the preliminary data from the epidemiological survey, the disease is obviously regional. However, considering the cause may exist in the environment, it is suspected as a natural epidemic disease. The area adjacent to the meadow wasteland, especially in the district animal community (?) Dendrolimus and its ectoparasites peaked during the epidemic season is worth reviewing. In order to explore the clues of the relationship between dental animals and their parasitic rot fungus (?) And Keshan disease epidemiology from the theory of natural foci, from September 1958 to 1958
