2001-2006年广州市麻疹病例血清学检测分析

Analysis of Serological Detection of Measles Cases in Guangzhou in 2001-2006

目的了解广州市2001-2006年麻疹血清学监测的状况和流行病学特点。方法对广州市2001-2006年疑似麻疹病例的流行病学和实验室血清学检测结果进行分析。结果2001-2006年共报告麻疹疑似病例7064例,麻疹IgM抗体阳性4498例,阳性率为63.67%。发病年龄以少儿和青年为主,大多数病例麻疹疫苗免疫史不详。结论应进一步提高流动人口MV接种率,加强麻疹实验室的监测,才能有效消除麻疹。

Objective To evaluate the status of measles serology surveillance and the epidemiological features of measles in Guangzhou. Method The epidemiology and laboratory results of the surveillance of the suspected measles cases during 2001 -2006 were analyzed. Results A total of 7 064 suspected measles cases have been reported in five years, in which 4 498 measles cases were positive in IgM antibody and the positive rate was 63.67%. Measles cases were mainly children and young adults, and most of them had uncertain measles vaccine imnlunization history. The status of measles surveillance system was normal, and the level of measles antibody of native population was higher than that of floating population. Most outbreaks occurred in the floating population and it was the reason that the measles incidence was somewhat high in Guangzhou. Conclusion To speed up the process of measles control, it is important to carry out enhanced immunization among those in high risk to measles, and to enhance the construction of measles surveillance system as well as the measles laboratory network.
