北京市2071例SARS排除病例分析

Analysis on 2071 cases excluded from severe acute respiratory syndrome in Beijing

目的 分析严重急性呼吸综合征(SARS)排除病例的基本特征和排除的原因。方法 对2003年3～6月间北京市被排除的2071例临床诊断和疑似SARS病例进行分析;用SPSS 10.0软件进行统计学分析。结果 SARS排除病例中男性约三分之二,女性约三分之一;职业以民工最多,其次为学生和离退休人员。排除日期的分布主要有三个高峰,6月7～13日是病例排除的高峰。患者从发病到排除的时间间隔呈现两个形状不同的峰,一个峰为发病后6～10天,另一个峰在发病后48～52天。有密切接触史的患者发病后50天方被排除的比例明显高于无密切接触史的被排除病例。1211例病例有明确的更正诊断,所患疾病主要为肺炎、病毒性感冒、肺部感染等呼吸道疾病。结论 应该加强SARS的鉴别诊断,减少临床误诊。

Objective To examine the characteristics of cases excluded from severe acute respiratory syndrome(SARS) and the reasons for exclusion. Methods 2071 probable or suspected cases excluded from SARS between March and June, 2003 were analyzed. Results Two-thirds of the excluded cases were males. Construction workers, students and retired people ranked top three in all the occupation categories. Three peaks appeared in the dates of exclusion, and the most obvious one was from June 7 to June 13. There were two peaks in the distribution of time period from onset to exclusion, one was six to ten days and the other was forty-eight to fifty-two days after onset. Patients with history of close contact were more likely to be excluded within fifty days after onset than those without close history of contact. Pneumonia, common cold and lung infection were the leading causes for correction in the 1211 excluded cases. Conclusion Study on the diagnosis and differential diagnosis should be emphasized.
