目的:了解余杭区健康人群麻疹免疫水平现状,为麻疹防控提供依据。方法:采用分层随机抽样选择余杭区健康人群作为检测对象,用酶联免疫吸附试验(ELISA)检测人血清中麻疹IgG抗体。结果:余杭区人群麻疹抗体阳性率为94.48%,保护率61.90%。20~、30~岁年龄组抗体阳性率分别为87.50%、90.12%,保护率分别为55.00%、53.09%,均明显低于其他年龄段人群。结论:余杭区麻疹抗体水平总体水平较高。20~、30~岁年龄组的成人是目前该区麻疹发病的高危人群。积极开展成人麻疹类疫苗接种是当前麻疹防控的有效措施。
Objective: To understand the status of measles immunity in healthy population in Yuhang District, and to provide basis for prevention and control of measles. Methods: Stratified random sampling was used to select the healthy population of Yuhang District as the testing object, and the serum IgG in measles was detected by enzyme - linked immunosorbent assay (ELISA). Results: The positive rate of measles antibody in the population of Yuhang district was 94.48%, the protection rate was 61.90%. The positive rates of antibodies in 20 ~ 30 years old group were 87.50% and 90.12% respectively, the protection rates were 55.00% and 53.09%, respectively, which were significantly lower than those in other age groups. Conclusion: The level of measles antibody in Yuhang District is generally high. 20 ~, 30 ~ age group of adults is the highest risk of measles in this area. Active adult measles vaccination is an effective measure to prevent and control measles.
