目的了解荔湾区健康人群麻疹抗体水平,为制定免疫策略和评价免疫效果提供依据。方法2007年在荔湾区随机抽取部分健康人员检测血清麻疹抗体水平。结果共抽取420人,荔湾区健康人群麻疹抗体总阳性率为68.1%,保护率为60%,平均几何滴度为1:216,年龄组间麻疹抗体阳性率、保护率、GMT经统计学检验,差异均有统计学意义(P<0.05);不同性别麻疹抗体阳性率、保护率、经统计学检验,差异均无统计学意义(P>0.05)。结论我区健康人群麻疹抗体水平处于较低水平,近几年麻疹发病呈现上升趁势,建议及时并扩大范围接种麻疹疫苗,提高接种率,保证较高保护率,形成有效的免疫屏障,才能有效地控制麻疹。
Objective To understand the level of measles antibody in healthy population in Liwan District, and to provide basis for developing immunization strategy and evaluating the immune effect. Methods In 2007, some healthy people were randomly selected to detect the level of serum measles antibody in Liwan District. Results A total of 420 samples were collected. The total positive rate of measles antibody in healthy population in Liwan District was 68.1%, the protective rate was 60% and the average geometric titer was 1: 216. The positive rate of measles antibody, the protection rate and the GMT of the age group were statistically tested (P <0.05). There was no significant difference in the positive rate and protection rate of measles antibody between different sexes (P> 0.05). Conclusion The measles antibody level of healthy people in our district is at a low level. In recent years, the incidence of measles has been on the rise. It is suggested that measles vaccine should be extended in a timely and wide range, the vaccination rate should be increased, the higher protection rate should be ensured, and an effective immune barrier should be effectively established Control measles.
