人禽流感疫情分析及其防控策略探讨

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。
