我组在1953年曾对辽宁省境内的锦洲、沈阳、四平和吉林省的长春以及黑龙省的哈尔滨市等地流行性乙型脑炎隐性感染进行了调查。根据实验结果,曾提出哈尔滨市有发生流行性乙型脑炎的可能性。但对哈尔滨更北地区尚无充分的了解。我们为进一步了解东北区乙型脑炎的疫区范围,特别是哈尔滨以北地区的情况。在1956年对黑龙江省境内的双城、哈尔滨、齐齐哈尔、佳木斯等地区的流行性乙型脑炎隐性感染进行了调查。
In 1953, our group investigated the latent infection of Japanese encephalitis (JE) in Jinzhou, Shenyang, Siping and Changchun in Jilin Province and Harbin in Heilongjiang Province in 1953. According to the experimental results, it has been proposed that there is a possibility of occurrence of Japanese encephalitis in Harbin. However, there is no adequate understanding of the northern part of Harbin. To understand more about the epidemic area of Japanese encephalitis in Northeast China, especially in the area north of Harbin. In 1956, Heilongjiang Province in Shuangcheng, Harbin, Qiqihar, Jiamusi and other regions of the Japanese encephalitis latent infection were investigated.
