This study compares the main causes of influenza epidemics reported in Czechoslovakia (CSR) and the German Democratic Republic (GDR) during the 9 seasons between 1980 and 1988. The influenza epidemics due to identical virus types were experienced in the two countries in the 1980, 1984 and 1986 seasons, and of these only the 1984 epidemic associated with A-strain influenza A/Chile/1/83 (H1N1) virus could be demonstrated to spread from the eastern parts of the CSR to the northern areas of the GDR. This implies that influenza epidemics due to identical drift variants spread only exceptionally from one country to the other during the period of observation, in spite of a busy tourist activity across the borderline.
本研究比较了1980年至1988年9个季节期间捷克斯洛伐克（CSR）和德意志民主共和国（GDR）报告的流感流行主要原因。1980年、1984年和1986年这两个国家经历了由相同病毒类型引起的流感流行，其中只有1984年与甲型流感A/智利/1/83（H1N1）病毒相关的流行被证明是从捷克斯洛伐克东部地区传播到德意志民主共和国北部地区的。这意味着，尽管边境地区旅游活动频繁，但在观察期内，由相同漂移变异株引起的流感流行仅在极个别情况下从一个国家传播到另一个国家。
