2005-2006年浙江省不明原因肺炎病例监测结果分析

Analysis on surveillance results of unexplained pneumonia cases in Zhejiang from 2005 to 2006

目的分析2005-2006年浙江省不明原因肺炎病例监测结果,为制定传染性非典型肺炎(SARS)和人禽流感防制策略提供帮助。方法对2005-2006年浙江省不明原因肺炎监测资料进行统计分析。结果2005-2006年浙江省累计报告不明原因肺炎病例29例,除去误报病例9例,协助外省调查病例3例,本省实际报告病例17例,其中1例被确诊为人感染高致病性禽流感;报告病例男女性别比为1.43:1;以儿童和老年人为主;冬、春季为高发季节,占82.35%;职业构成以农民为主;就诊时符合流感样病例数为14例,占82.35%。结论不明原因肺炎患者就诊时所伴有的流感样症状具有较为重要的临床意义;应进一步规范不明原因肺炎的诊断和报告,为早期发现SARS和人禽流感病例提供帮助。

Objective The study was conducted to analyze the surveillance results of unexplained pneumonia cases in Zhejiang from 2005 to 2006 for the formulation of strategies for the prevention and control of SARS and Human avian influenza. Methods Statistical analysis were performed on the surveillance data of unexplained pneumonia in Zhejiang Province from 2005 to 2006. Results 29 cases of unexplained pneumonia were reported from 2005 to 2006 in Zhejiang. Nine mistaken cases and three cooperatively investigated cases in other provinces excluded, there were actually 17 reported cases, one case of which was diagnosed high-pathogenic human avian influenza. The reported ratio of male to female was 1.43：1. Children and aged people were mostly affected. 82.35% of unexplained pneumonia cases were reported in winter and spring. Farmers were the major affected occupation. 14 cases were found with influenza-like symptoms when sent to the hospital, accounting for 82.35%. Conclusion Influenza-like symptoms were clinically significant for the diagnosis of unexplained pneumonia. Clinical diagnoses and reports of unexplained pneumonia cases should be normalized to favor the early discovery of cases of SARS or human avian influenza.
