An epidemic of Asian (A2) influenza that occurred in the USSR early in 1965 was the fourth wave of Asian influenza there since 1957, when the disease became pandemic, spreading through all countries and continents. The 1965 epidemic was severe, in several cities even more so than the 1957 pandemic. Study of the antigenic structure of the viruses isolated during the latest epidemic indicated that the viruses were similar to those isolated in western Europe in 1964 (A2/England 12/64) but that their structure showed a further shift away from that of the prototype virus (A2/Singapore 1/57). The 1957 and 1959 pandemics followed similar courses, starting in China. The third wave affected Europe. North Africa and Asia in winter 1960-61, but did not reach the USSR until the following winter. The fourth wave was more complex, spreading in Asia in 1962-63 and in Europe and America in 1963-64; it reached the USSR at the beginning of 1965. The way in which the structure of the A2 virus has changed since 1957 is discussed.
1965年初在苏联发生的亚洲（A2）型流感疫情是自1957年该病成为大流行病并蔓延至所有国家和各大洲以来，苏联出现的第四波亚洲流感。1965年的疫情很严重，在几个城市甚至比1957年的大流行更为严重。对最近疫情期间分离出的病毒的抗原结构进行研究表明，这些病毒与1964年在西欧分离出的病毒（A2/英格兰12/64）相似，但它们的结构显示出与原型病毒（A2/新加坡1/57）的结构有进一步的差异。1957年和1959年的大流行过程相似，均始于中国。第三波疫情在1960 - 1961年冬季影响了欧洲、北非和亚洲，但直到次年冬季才蔓延至苏联。第四波疫情更为复杂，于1962 - 1963年在亚洲蔓延，1963 - 1964年在欧洲和美洲蔓延；1965年初蔓延至苏联。文中讨论了自1957年以来A2病毒结构的变化方式。
