目的:对2012年广州市越秀区疑似麻疹风疹的血清学结果进行整理分析,以了解麻疹风疹病例的流行特点。方法:选取2012年1月-2012年12月的166例疑似麻疹风疹患者的血清作为研究对象,统计血清中IgM阳性抗体的检出情况,以及各年龄段、月份IgM抗体阳性的例数及构成比。结果:麻疹风疹疑似病例中有36.1%的患者检测出IgM抗体阳性,其中麻疹IgM阳性以0-1岁婴幼儿的检出率较高,可达44.4%。从月份来看,12月、8月和5月是麻疹的好发时期。风疹IgM阳性以20岁以上中老年患者检出率最高,为75.0%,7月、4月和5月是风疹的易感季节。结论:疑似麻疹风疹病例有较高的IgM抗体阳性检出率,0-1岁婴幼儿和20岁以上中老年人是麻疹风疹的易感人群,4-5、7-8和12月是发病的高峰时期,临床应注意加强防范。
Objective: To analyze the serological results of suspected measles and rubella in Yuexiu District of Guangzhou City in 2012 to understand the epidemiological characteristics of measles and rubella cases. Methods: From January 2012 to December 2012, 166 cases of suspected measles and rubella sera were selected as the research objects, the detection of serum IgM-positive antibodies and the positive number of IgM antibodies in all age groups and months ratio. RESULTS: Thirty-six (36.1%) of the suspected cases of measles and rubella were detected positive for IgM antibody. The detection rate of measles IgM positive children and infants aged 0-1 years was 44.4%. From the month of view, December, August and May are good times for measles. Rubella IgM positive in 20 years of age and above the highest detection rate of middle-aged patients, 75.0%, July, April and May are susceptible to rubella season. CONCLUSIONS: The prevalence of IgM antibodies in suspected measles and rubella cases is high, and susceptible populations of measles and rubella are among 0-1 year-old infants and middle-aged and elderly people over 20 years of age. Peak period, clinical should pay attention to strengthen prevention.
