摘要
目的对2007—2016年汉中市麻疹疑似病例实验室检测结果进行分析,了解汉中市麻疹流行趋势,为防控和消除麻疹提供科学依据。方法采集麻疹疑似病例血清和咽拭子标本,分别检测患者血清中麻疹IgM抗体和咽拭子中的麻疹病毒核酸。结果 2007—2016年汉中市共报告麻疹疑似病例518例,检出阳性205例,阳性率为39.58%。不同年份之间麻疹阳性率差异有统计学意义(χ~2=101.09,P<0.05)。麻疹发病高峰为3—6月,病例数为144例,占总病例数的70.24%。<30岁年龄组为麻疹高发年龄组,共172例,占比为83.90%。麻疹病例主要集中在洋县(32例)、南郑县(26例)和略阳县(25例)。结论 2007—2016年汉中市麻疹发病总体上呈下降趋势,但为了实现消除麻疹的目标,卫生部门仍应加强麻疹监测工作。
[Objective]To analyze the laboratory test results of suspected measles cases in Hanzhong City from 2007-2016,understand the epidemiological trends of measles,and provide scientific evidence for measles control and elimination.[Methods]The serum and pharyngeal swab specimens were collected from suspected measles cases to detect measles-specific Ig M antibodies and viral nucleic acid respectively.[Results]A total of 518 suspected measles cases were reported from 2007-2016 in Hanzhong City and 205 cases were confirmed by laboratory testing with the positive rate of 39.85%. There was statistically significant difference in the positive rate between different years（χ~2=101.09,P〈0.05）. The peak season appeared March to June,with 144 cases,accounting for 70.24% of the total cases. People under 30-year-old were the high-risk groups,with 172 cases,accounting for83.90%. The measles cases mainly concentrated in Yangxian County（32 cases）,Nanzheng County（26 cases）and Lueyang County（25 cases）.[Conclusion]The trend of measles morbidity is generally decreasing in Hanzhong city from 2007 to 2016,but health department should still strengthen the measles surveillance to achieve the goal of measles elimination.
