目的了解2010年息县人群麻疹免疫水平,为制定消除麻疹措施和策略提供科学依据。方法在全县10个乡镇共随机抽样0～14岁常住健康人群3 436人,用ELISA法检测麻疹IgG抗体。结果麻疹IgG抗体阳性率为94.00%,其中男性阳性率为93.82%,女性阳性率为94.22%。不同乡镇、不同年龄组儿童之间麻疹免疫水平有统计学意义。结论息县基础免疫有免疫脱漏现象,个别乡镇麻疹接种率不高,建议加强8月龄MV初免及时性和提高复种接种率,重点加强麻疹IgG抗体水平较低乡镇的MV基础免疫和查漏补种,适时开展麻疹强化免疫。
Objective To understand the level of measles immunity in Xixian County in 2010 and provide a scientific basis for formulating measles elimination measures and strategies. Methods A total of 3 436 resident healthy population from 0 to 14 years old in 10 townships of the county were enrolled. Measles IgG antibody was detected by ELISA. Results The positive rate of measles IgG antibody was 94.00%, of which the positive rate was 93.82% in males and 94.22% in females. Measles immunity levels among different towns and children of different age groups were statistically significant. Conclusions Immunosuppression in the basic immunization of Xixian County is rare. The measles immunization rate in individual townships is not high. It is suggested that the timeliness of 8-month-old MV immunization and the vaccination coverage should be improved. The basic immunization and detection of MV in villages and towns with low levels of measles IgG should be strengthened Breeding, timely measles to strengthen immunity.
