SARS相关症状留观病人的流行病学分析

Epidemiological analysis of cases with SARS like fever to be observed

[目的] 为了解SARS相关症状留观病人的流行病学特征。 [方法] 用个案调查方收集SARS相关症状留观病人资料,进行描述性分析。 [结果]181例发热留观病例,男女性比1:0.98;学龄前儿童占12.15％,16-45岁青壮年占53.04%;26.53％有外出史;初次就诊至确定留观天数0.98d,平均留观天数2d;最终诊断为细菌性肺炎44.19％,支原体肺炎11.60％,军团菌肺炎2.76％。实验室咽拭子培养诊断结果:支原体阳性率10.41％,军团菌阳性率5.21%。实验室血清IgM检测结果:军团菌16.88％,乙型流感病毒15.58％,支原体11.68％。 [结论] 本组资料中留观病人流行病学特征与SARS基本不相符合。

[Objective] To understand the epidemiological characteristics of cases with fever to be observed. [Methods] To collect 1S1 cases information by face- to- face investigation, and make analysis. [Results] Of the 181 cases, the ratio of male to female was 1:0.98; the percentage of per- education children was 12.15%, the percentage of young adults (aged 16 - 45) was 53. 04 % . 26. 53 % of cases had history of egress The average length from first visit to hospitalization to be observed was0. 98 days The average length of observation was 2 days. The percentage of bacteria pneumonia as final diagnosis was 44.19% , myccplasmal pneumonia was 11. 60% , legionaires' pneumonia was 2. 76% . Throat swab positive of mycoplasmal was 10.41% . Detection of legionaires' was 5.21%. The positive serological IgM antibody for legionella was 16. 88 % for flu was 15.58% and for mycoplasmal was 11.68% . [Conclusion] The epidemiological characteristics of cases with fever to be observed was basically different from SARS.
