目的了解无锡市新区成年外来人口麻疹抗体水平,为制定新区控制和消除麻疹的措施提供依据。方法随机抽取无锡市新区健康成年外来人群共计823人进行麻疹IgG抗体水平检测及相关问卷调查。结果调查非无锡本地户籍外来务工人员823名,血清麻疹抗体IgG阳性率仅为30.13%,保护性抗体阳性率为25.52%;抗体几何平均滴度为1∶179,该类人群麻疹免疫水平远低于保护水平。结论无锡新区成年外来人群麻疹病毒免疫水平低下,在合适的条件下极易造成麻疹的流行或暴发。
Objective To understand the level of measles antibody in adolescent population in Wuxi New District and provide the basis for the development of new area control and measles elimination measures. Methods A total of 823 healthy adolescents from Wuxi New District were randomly selected for measles IgG antibody levels and related questionnaires. Results A total of 823 non-Wuxi migrant workers were investigated. The positive rate of serum measles antibody IgG was only 30.13% and the positive rate of protective antibody was 25.52%. The geometric mean antibody titer was 1:179. The level of measles immunity in such people was far lower At the level of protection. Conclusion The level of measles virus immunodeficiency in adolescents from Wuxi New District is very low. Under the proper conditions, it is very easy to cause the epidemic or outbreak of measles.
