During the 1991-92 influenza season, influenza activity was reported at moderate levels in many parts of the world. Influenza A(H1N1), A(H3N2), and influenza B viruses have continued to circulate worldwide. From October 1991 through February 1992, when influenza viruses circulated widely in the Northern Hemisphere, epidemic levels of activity were most commonly associated with the H3N2 subtype of influenza A (1). This report summarizes worldwide influenza activity reported from March through September 1992 and activity in the United States from October 1991 through September 1992.
在1991 - 1992年流感季节期间，世界许多地区报告流感活动处于中等水平。甲型（H1N1）、甲型（H3N2）流感病毒以及乙型流感病毒继续在全球传播。从1991年10月到1992年2月，当流感病毒在北半球广泛传播时，流感活动的流行水平最常与甲型H3N2亚型流感相关（1）。本报告总结了1992年3月至9月全球报告的流感活动以及1991年10月至1992年9月美国的流感活动情况。
