目的了解桐柏县人群麻疹免疫状况,考核及评价麻疹疫苗的接种质量和效果,为消除麻疹策略提供依据。方法2011年4—6月随机抽样采集血标本360份,采用ELISA测定麻疹IgG抗体。对不同性别、乡镇和年龄组的人群麻疹免疫水平监测结果进行统计学分析。结果人群麻疹抗体阳性率为95.56%,男女麻疹抗体阳性率差异无统计学意义(P>0.05);不同年龄、不同乡镇之间人群阳性率差异均有统计学意义(均P<0.05)。结论桐柏县麻疹IgG抗体阳性率较高,但15岁以上抗体阳性率相对较低,说明该年龄段接种情况较差,需加强此年龄段的免疫接种工作。
Objective To understand the immune status of measles in Tongbai County and evaluate and evaluate the vaccination quality and effectiveness of measles vaccine so as to provide basis for eliminating measles. Methods A total of 360 blood samples were collected from April to June in 2011 and measles IgG antibodies were detected by ELISA. The results of surveillance of measles immunity in different gender, township and age groups were statistically analyzed. Results The positive rate of measles antibody in the population was 95.56%. There was no significant difference in the positive rate of measles antibody between male and female (P> 0.05). The positive rates of measles antibody in different age and different townships were significantly different (all P <0.05). Conclusions The positive rate of measles IgG antibody in Tongbai County is relatively high, but the positive rate of antibodies over 15 years old is relatively low, which indicates that vaccination at this age is poor and immunization needs to be strengthened at this age.
