目的了解我国健康人群乙脑免疫状况,为乙脑的预防和控制提供参考。方法以乙脑、抗体水平/血清学为检索词,检索1990~2009年中国全文数据库、中国生物医学数据库、博、硕士学位论文全文数据库及会议论文全文数据库。结果共检索到相关文献38篇,健康人群乙脑抗体水平无性别差异,不同年龄段的乙脑抗体水平不同,不同地区乙脑抗体水平存在差异,最低乙脑抗体阳性率为18.6%,最高为90.3%。结论健康人群的乙脑抗体水平可以综合反映免疫接种和自然感染状况,对了解当地乙脑的流行和免疫状况具有重要参考作用。
Objective To understand the immune status of Japanese encephalitis in healthy population in China and provide reference for the prevention and control of Japanese encephalitis. Methods Etiology of JE and antibody levels / serology was used as a search term to search the Chinese full-text database, Chinese biomedical database, full-text database of dissertations and master’s degree theses and the full-text database of conference dissertations from 1990 to 2009. Results A total of 38 articles were retrieved. There was no gender difference in the antibody levels of JE in healthy people. The antibody levels of JE were different at different ages. The antibody levels of JE were different in different regions. The lowest positive rate of JE was 18.6% 90.3%. Conclusions The antibody level of JE in healthy population can reflect the status of immunization and natural infection comprehensively, which is of important reference for understanding the epidemic and immune status of JE.
