作者对日本1976年11月至1981年3月,五年内流行性感冒样患者发病情况和1980至1981年的流行情况,就病毒学和血清学进行了探讨,结果如下: 1.1976～1981年五年内,虽然全年均有流行,但是发病高峰均在1月下旬到2月下旬约一个月内。2.在1980～1981年流行期间共分离出病毒1,100株,为多株流行,其中,A苏联型(H_1N_1)718株(65.3%)、A香港型(H_3N_2)150株(13.6%)、B型232株(21.1%)。3.从被分离的A苏联型(H_1N_1)、A香港型(H_3N_2)、B型的全部型别来看,与1980年度的疫苗之间抗原有变异。4.在这次流行中被分离的B型中,抗原变异较大的是B/滋贺/75/81株及其类似株。
The author of the Japanese from November 1976 to March 1981, five years of influenza-like illness and the prevalence of 1980 to 1981, the virology and serology were discussed, the results are as follows: 1. 1976 to 1981 in five years , Although the epidemic throughout the year, but the peak incidence in late January to late February about one month. A total of 1,100 strains were isolated during the period from 1980 to 1981, of which 718 (65.3%) were A type (H_1N_1), 150 (13.6%) were A type (H_3N_2), B Type 232 (21.1%). 3. From the total number of A type (H_1N_1), A Hong Kong (H_3N_2) and type B isolated, there was a variation in the antigen between 1980 and the vaccine. Among the type B strains isolated in this epidemic, B / Shiga / 75/81 strains and their similar strains have a large variation in the antigen.
