上海市卢湾区人群麻疹免疫水平监测

Population measles immune level monitor in Luwan district of Shanghai

[目的 ] 了解卢湾区近 10年人群麻疹免疫水平与麻疹发病情况的关系。 [方法 ] 对卢湾区 1989～1999年人群麻疹免疫水平和麻疹发病情况资料进行分析 ,并计算抗体阳转率、发病率。 [结果 ] 历年接种率维持在97%以上的较高水平。免后抗体阳性率为 99.42 %,几何平均滴度 (GMT)为 39.96。人群麻疹抗体总阳性率为99 .49%,近几年麻疹年均发病率在 0 .19/ 10万以下。 [结论 ] 在保持高接种率和免疫成功率的基础上 。

Objective] To explore the relation between immune level in healthy people of different age and incidence of measles in Luwan district in recent 10 years. [Methods] By analysing the population immune level and incidence of measles, antibody positive rate and incidence of measles were calculated. [Results] The immunization coverage rate of measles vaccine (MV) was more than 97%. The positive seroconversion rate of post-vaccination was 99.42% and the geometric mean titer (GMT) was 97.43%. The incidence of measles decreased gradually to under 0.19/100,000. [Conclusion] Mobile children and adult people are the focal target for control measles while a high-level coverage rate and a high quality vaccination in population is maintained.
