目的了解入伍新兵人群中风疹病毒IgG抗体的流行分布情况,为今后预防提供科学依据。方法采用血清流行病学调查方法,利用酶联免疫吸附试验(ELISA)技术,对北京军区近4年来自8个省市的360名入伍新兵血清进行了风疹病毒IgG抗体检测,统计分析其阳性率。结果发现各年间入伍新兵血清中风疹病毒IgG抗体呈逐年增高趋势,为91.23%～100.00%,平均95.56%;地区间无显著差别,河南省(100.00%)、甘肃省(97.67%)、江西省(97.50%)和四川省(97.02%)较高,江苏省(91.23%)、广西省(92.00%)和河北省(94.00%)较低;入伍前工作与否,抗体阳性检出率无显著性差别。结论入伍新兵人群中风疹病毒IgG抗体阳性率为91.23%～100.00%,并呈逐年增高趋势,地区间差异无统计学意义;新兵人群风疹病毒抗体水平较高,形成了免疫保护屏障。
Objective To understand the epidemiological distribution of rubella virus (IgG) antibody among recruits in new recruits and provide a scientific basis for future prevention. Methods The serological epidemiological survey method was used to detect rubella IgG antibody against 360 recruits from 8 military provinces and cities in Beijing Military Region in the past 4 years by enzyme-linked immunosorbent assay (ELISA). The positive rate of rubella virus IgG was detected by statistical analysis . The results showed that the serogroup rubella virus (IgG) antibody levels increased from 91.23% to 100.00%, with an average of 95.56% in the recruit serogroups in each year. There was no significant difference between the two regions in Henan Province (100.00%), Gansu Province (97.67%), Jiangxi Province (97.50%) in Sichuan province and 97.02% in Sichuan province (91.23%) in Guangxi province (92.00%) and Hebei province (94.00%). There was no significant positive rate of antibody positive Sex difference. Conclusions The positive rate of rubella virus IgG among recruits was 91.23% -100.00%, showing a trend of increasing year by year. There was no significant difference between regions. The anti-rubella virus antibody level of newly recruited people formed a protective barrier of immunity.
