During the 11 influenza seasons from 1977 through 1988, more than 10,000 excess deaths attributed to pneumonia and influenza (P&I) were reported during each of seven seasons, and approximately 45,000 deaths were reported during each of two seasons (CDC, unpublished data, 1992). The most important strategy for preventing influenza-associated morbidity and mortality is vaccination of persons in high-risk groups with vaccine closely matched to circulating strains. In collaboration with state and local health departments, CDC conducts surveillance to monitor influenza activity and to detect antigenic changes in the circulating strains of influenza virus. This report summarizes surveillance for influenza in the United States and worldwide during the 1991-92 season and describes the composition of the 1992-93 influenza vaccine.
在1977年至1988年的11个流感季节中，有7个季节每年报告的因肺炎和流感（P&I）导致的超额死亡超过10000例，有两个季节每年报告的死亡约为45000例（疾病控制和预防中心，未发表数据，1992年）。预防与流感相关的发病和死亡的最重要策略是为高危人群接种与流行毒株密切匹配的疫苗。疾病控制和预防中心与州和地方卫生部门合作，开展监测以监测流感活动并检测流感病毒流行毒株的抗原变化。本报告总结了1991 - 1992年季节美国和全球的流感监测情况，并描述了1992 - 1993年流感疫苗的成分。
