目的分析澄迈县健康人群麻疹和风疹抗体水平。方法采用随机抽样方法对澄迈县2011年各年龄段人群进行麻疹和风疹抗体IgG水平检测。结果 1~13岁麻疹和风疹抗体水平最高,麻疹风疹抗体阳性率分别为95.00%和99.50%。<6月龄婴幼儿抗体水平最低,麻疹和风疹抗体阳性率分别为42.00%和17.00%,与1~13岁年龄段人群抗体阳性率差异有统计学意义(P<0.01)。中学组风疹抗体阳性率明显低于小学组(P<0.01),成人组麻疹和风疹抗体水平阳性率均明显低于小学组(P<0.01);新生儿麻疹风疹抗体阳性率分别为70.00%、60.00%,接种组免疫后麻疹风疹抗体阳性率与免疫前相比差异有统计学意义(P<0.01),且免疫后麻疹风疹抗体水平均达到形成人群免疫屏障标准。结论澄迈县健康人群中,<6月龄和>14岁为易感年龄段,应针对不同年龄段人群分别采用不同措施防止麻疹和风疹的感染。
Objective To analyze the level of measles and rubella antibodies in healthy population in Chengmai county. Methods A random sampling method was used to detect measles and rubella IgG in all ages in Chengmai County in 2011. Results The highest level of measles and rubella antibodies was found between 1 and 13 years old. The positive rates of measles and rubella were 95.00% and 99.50% respectively. The antibody levels of measles and rubella were 42.00% and 17.00% respectively in 6-month-old infants and young children. The positive rate of antibody in measles and rubella was statistically significant (P <0.01). The positive rate of rubella antibody in middle school was significantly lower than that in primary school (P <0.01), and the positive rate of measles and rubella in adults was significantly lower than that of primary school (P <0.01). The positive rates of measles antibody in newborn were 70.00% 60.00%. The positive rate of measles rubella antibody in vaccinated group was significantly different from that before immunization (P <0.01), and the antibody level of measles and rubella reached the standard of immune barrier. Conclusions In the healthy population of Chengmai County, <6 months old and> 14 years old are susceptible age groups. Different measures should be taken for different age groups to prevent the infection of measles and rubella respectively.
