摘　　要：目的 调查≥15岁居民麻疹免疫水平并探讨阻断麻疹传播策略。方法 对江苏省603名≥15岁居民麻疹免疫水平进行血清流行病学调查，分离血清后采用酶联免疫吸附试验检测抗体，抗体阳性率比较运用χ2检验。结果 2012年共收集603份合格标本，苏北、苏南抗体阳性率分别为91.33%、95.36%，男、女性抗体阳性率分别为92.24%、95.69%，≥15岁居民抗体阳性率为94.36%，不同地区、性别、年龄居民抗体阳性率差异均无统计学意义，与2008年比较差异均无统计学意义；≥15岁居民麻疹几何平均滴度（GMT）随年龄增长呈下降趋势。结论 以8月龄-14岁儿童为对象的免疫策略对≥15岁居民麻疹发病影响较小，无法阻断麻疹病毒在全省范围内传播。Objective To investigate the immunity to measles virus in population aged ≥15 years in Jiangsu province and to explore stratiges for interrupting measles virus transmission.Methods Sero-survey on measles IgG antibody in 603 individuals aged ≥15 years in Jiangsu province was carried out,and the antibody was detected using enzyme-linked immunosorbent assay.Chisq-test was used to measure the differences in antibody positive rate.Results Totally 603 specimens were collected.The antibody seroprevalence of the populations in northern and southern were 91.33% and 95.36%;the seroprevalence of male and female were 92.24% and 95.69%;the seroprevalence of population aged ≥15 years in 2012 was 94.36%.There were no statistical differences in the positive rate among region,gender,and age groups.And no statistical difference in the positive rate of the population in 2012 was found when compared to that of 2008.The geometric mean titer in the population of ≥15 years decreased with age.Conclusion The immunization strategies targeted to the individuals aged 8 months to 14 years may not work to interrupt measles virus transmission,especially in the individuals aged ≥15 years.
