| 目的 分析北京市严重急性呼吸综合征 (SARS)流行病学特征。方法 对北京市疾病预防控制中心 2003年SARS疫情数据库进行分析。结果 北京市SARS流行过程分五个阶段,各阶段发病构成如下 :输入扩散期 (3月1～ 31日 )为 2.7% ;上升期 (4月1～ 15日 )为 13.6 % ;高峰期 (4月16日至5月4日 )为 71.0 % ;下降期 (5月5～ 18日 )为 11.6 % ;终止期 (5月19～2 8日 )为 1.1%。北京市SARS临床诊断病例 2521例,发病率为 18.5 7/10万,死亡 192例,死亡率和病死率分别为 1.4 1/10万和 7.6 %。男女发病比例为 1∶0.97,2 0～ 29岁组发病率最高 (30.85 /10万 ),0～ 14岁组最低 (2.5 4 /10万 ),患者以青壮年为主,占 72.3%。城区、近郊区和远郊区 (县 )发病率分别为 32.2 5 /10万、20.5 7/10万和 8.90 /10万,呈现随人口密度下降发病逐渐下降的趋势。不同职业中,医务人员 (17.3% )、干部职员 (12.9% )、离退休人员 (11.4 % )、工人 (9.7% )和家务待业人员 (8.8% )居发病构成前五位。病死率随年龄显著升高。结论 北京市是全球SARS流行强度最高的地区,但是病死率最低。 |
