目的了解呼和浩特市健康人群麻疹免疫状况,为进一步制定麻疹控制策略提供参考。方法 2012年抽取呼和浩特市4个县区,每个县区随机抽取2~4岁、7~9岁、13~15岁、20~25岁、30~35岁5个年龄组的健康人员约75人,全市共300人。应用酶联免疫吸附法检测麻疹Ig G抗体。结果 2012年共检测300人,其中麻疹Ig G抗体阳性282人,阳性率94.0%。经统计学分析,不同年龄组间的麻疹抗体阳性率差异有统计学意义(χ2=10.303,P<0.05),不同地区之间麻疹抗体阳性率差异无统计学意义(χ2=2.128,P>0.05)。结论呼和浩特市健康人群的麻疹抗体水平较高,其中0~4岁组最高,20~25岁组最低,建议继续提高麻疹疫苗的常规免疫接种率,尤其是针对大年龄组人群开展强化免疫,同时继续加强麻疹监测,努力实现消除麻疹的目标。
Objective To understand the immune status of measles in healthy population in Hohhot and to provide reference for further development of measles control strategy. Methods In 2012, 4 counties in Hohhot were selected, and healthy population of 5 age groups of 2 ~ 4, 7 ~ 9, 13 ~ 15, 20 ~ 25, 30 ~ 35 were randomly selected in each county. People, the city a total of 300 people. Measles Ig G antibody by enzyme-linked immunosorbent assay. Results A total of 300 persons were detected in 2012, of which 282 were measles Ig G positive, the positive rate was 94.0%. Statistical analysis showed that there was significant difference in measles antibody positive rate among different age groups (χ2 = 10.303, P <0.05), and there was no significant difference in measles antibody positive rate among different regions (χ2 = 2.128, P> 0.05 ). Conclusion The measles antibody level of healthy population in Hohhot is relatively high, among which the highest in 0 ~ 4 years old group and the lowest in 20 ~ 25 years old group, it is recommended to continue to raise the routine immunization rate of measles vaccine, especially for the large age group. Continue to strengthen measles surveillance and strive to eliminate measles.
