阜南县2005年麻疹血清学监测结果分析

Analysis of Measles Serological Surveillance in Funan County in 2005

目的了解麻疹疑似病例实验室诊断符合率及健康人群麻疹抗体水平,为进一步提高麻疹监测工作质量提供依据。结果2005年共监测报告疑似麻疹病例110人,其中暴发病例34人,散发病例76人;暴发病例采集血标本30份,散发病例采集血标本65份,麻疹IgM抗体阳性率分别为96.67%和56.92%。对健康人群9个年龄组171份血标本检测,结果麻疹IgM阳性(≥1∶200)率98.83%。结论阜南县麻疹监测系统灵敏度较高。健康人群麻疹抗体水平高,已形成较为稳固的免疫屏障,近期不会造成人群的麻疹大面积暴发疫情。在加速控制麻疹阶段实验室诊断尤为重要。

Objective To identify coincidence proportion of laboratory test among measles -like cases and the antibody level of measles among healthy people, to improve the quality of the surveillance system. Method Blood specimens from measles cases and healthy people were collected and tested for IgM of measles virus. Results Totally 110 measles - like cases were reported by the surveillance system, among which 34 cases from measles outbreaks and 76 cases from non - outbreaks.
