摘　　要：目的了解近年来人禽流感疫情情况及其流行病学特征,为有效防控人禽流感提供科学依据。方法收集2003年以来世界卫生组织、中国卫生部网站人感染高致病性禽流感疫情信息公布资料,分析其流行病学特征,探讨人禽流感防控策略。结果全球自2003年以来累计报告人禽流感确诊病例516例,死亡306例,病死率为59.30%。其中,中国累计报告确诊病例40例,死亡26例,病死率为65.0%,高于全球平均水平;冬、春季为疫情高发季节;儿童、青壮年多发,中青年病死率较高;男女发病率间无显著性差异。结论人禽流感病死率高,病毒可能已经发生变异并突破种间屏障,传播能力增强,人传人风险增加,对人类危害大。应积极采取措施,有效防控人禽流感的发生。Objective To understand the epidemic situation and the epidemiological characteristics of human avian influenza in recent years, and to provide the scientific evidences for prevention and control the human avian influenza effectively. Methods Collected the information announcement material of human avian influenza on the World Health Organization and the Ministry of Public Health of China website since 2003 were collected, and its epidemiology characteristics were analyzed, the prevention and control strategies were discussed. Results The cumulative number of confirmed human cases of avian influenza A H 5 N 1 reported to WHO were 516 cases since 2003 in the world, with the death cases of 306, the case fatality rate was 59.30%. and chinese cumulative number of confirmed human cases of avian influenza A/（H5N1）were 40, including 26 death cases, the case fatality rate was 65.0% , was higher than the global average level. The human avian influenza had mostly happened in winter and spring. The children and the young adults had the mostly proportion in all the cases, the young adults ’ case fatality rate was high. There was no statistical significance between the male and female. Conclusion The case fatality rate of human avian influenza is high, the virus may be undergo variation and break through the inter-species barrier, it ’ s ability of infection has strengthened. The risk of infection by people to people is increasing, The disease has a serious hazard to human. Should take the measures positively to prevent and control the human avian influenza effectively.
