摘要
目的了解重庆市九龙坡区2～39岁健康人群麻疹IgG抗体阳性率,为制定麻疹控制策略提供依据。方法按流动人口和常住人口分层,随机抽取2～4岁、5～7岁、8～10岁、11～13岁、14～16岁、17～19岁、20～29岁、30～39岁8个年龄组健康人群共计820人,采集静脉血用酶联免疫吸附试验法检测麻疹IgG抗体。结果 8个年龄组麻疹IgG抗体阳性率为82.86%～95.10%,其中30～39岁组阳性率最低82.86%,年龄与麻疹抗体阳性率线性负相关;常住人口与流动人口麻疹抗体阳性率存在差异,分别为93.13%和89.16%;0剂次、1剂次、2剂次、3剂次及以上抗体阳性率分别为51.92%、92.13%、95.19%和98.31%,接种针次和麻疹抗体阳性率存在线性趋势。结论针对此次监测结果,在现有麻疹控制策略上应巩固常规免疫、强化流动人口管理、完善监测系统、重点人群强化免疫、加强冷链管理和积极宣传动员。
Objective To investigate the positive rates of measles IgG antibody of 2 - 39 years old health people in Jiulongpo district of Chongqing, so as to provide evidence for making control strategies for eliminating measles. Methods Stratified sampling was conducted over floating population involving 820 health people, and the object were randomly divided into 8 age groups based on age. The Venous Blood Enzyme Linked Immunosorbent As- say Method was applied to detect measles IgG antibody. Results Positive rates of measles IgG antibody in 8 age groups ranged from 82. 86% to 95. 10%, and the rate of 30 -39 age group was the lowest （82. 86% ）. Posi- tive rates in resident population and floating population were of statistically difference, 93.13% and 89. 16% respectively. Vaccination dose and positive rate showed a linear correlation ; positive rates of the dose at 0, 1, 2, 3 or above was 51.92%, 92. 13%, 95.19% and 98.31% respectively. Conclusion Control strategies and measures including routine immunization, management of floating population, immune system for focus groups and the cold chain management for vaccine and on should be further strengthened or improved.
