目的:分析镇雄具人群麻疹免疫抗体水平监测结果,及时了解人群免疫疫苗接种情况。方法:我科在2009年9月随机抽取镇雄县4个乡镇543人,分成15个年龄段,进行麻疹,白喉免疫抗体水平进行监测,使用酶联免疫吸附试验分别检测麻疹IgG抗体。结果:此次调查镇雄县人群麻疹抗体阳性率为95.2%,随着年龄的增加,人群体内的阳性率不断减少,成年人阳性率明显低于幼儿的阳性性,差异明显,具有统计学意义。结论:随着年龄增加,麻疹抗体水平呈下降趋势,有些人会消失,所以应该加强对成年人的麻疹疫苗预防接种。
OBJECTIVE: To analyze the results of monitoring the level of measles antibody in Zhenxiong population and keep abreast of immunization vaccination in population. Methods: In September 2009, our department randomly selected 543 people from 4 townships in Zhenxiong County and divided them into 15 age groups to monitor measles and diphtheria immune antibody levels. Measles IgG antibodies were detected by enzyme linked immunosorbent assay. Results: The positive rate of measles antibody in Zhenxiong County population was 95.2%. With the increase of age, the positive rate of measles antibody in the population decreased continuously. The positive rate of adult was significantly lower than that of young children, with significant difference, with statistical significance . CONCLUSIONS: With age, measles antibody levels are declining and some may disappear, so vaccination against adult measles vaccines should be strengthened.
