2014年成都市健康人群乙脑、乙肝抗体水平监测

Japanese Encephalitis and Hepatitis B Antibody Level Among Healthy People in Chengdu,2014

目的了解成都市健康人群乙脑、乙肝抗体水平,为制定有效的防治措施提供依据。方法于2014年对成都市〈1岁、1~2岁、3~4岁、5~6岁、7~14岁、15~19和≥20岁7个年龄组,每组随机抽取不少于30人,采集血清。采用ELISA法检测人群血清中的乙脑和乙肝表面抗体（HBs Ab）,并进行统计分析。结果乙脑Ig G抗体阳性率及GMC为41.89%、0.47 IU/ml,乙肝表面抗体（HBs Ab）阳性率及GMC为57.30%、10.96 m IU/ml。乙脑Ig G抗体阳性率以3~4岁组抗体阳性率最高、〈1岁最低,乙肝表面抗体（HBs Ab）阳性率及GMC以〈1岁组抗体阳性率最高、5~6最低。结论结合本次监测结果,加强儿童乙脑、乙肝常规免疫,做好新入学入托儿童乙脑、乙肝疫苗的查漏补种工作,确保人群的抗体水平保持在较高水平,以预防和控制乙脑和乙肝。

Objective To analyze the epidemic of Japanese Encephalitis and Hepatitis B antibody levels,and provide evidence for effective prevention and control measures. Methods The health people were divided into 7age groups（ 1 year,1 ~ 2 years,3 ~ 4 years,5 ~ 6 years,7 ~ 14 years,15 ~ 19 years and ≥20 years）,each group was not less than 30 cases. The serum samples were collected to detect the Japanese encephalitis and Hepatitis B antibody levels based on ELISA,and the data was analyzed by statistical method. Results Japanese encephalitis antibody positive rate and GMC were 41. 89% and 0. 47 IU / ml; Hepatitis B antibody positive rate and GMC were 57. 30% and 10. 96 m IU / ml. Japanese encephalitis antibody positive rate in 3 ~ 4years group was the highest,and the rate in 1 year group was the lowest; HBs Ab positive rate and GMC in 1 year group was the highest,and the rate in 5 ~ 6 years group was the lowest. Conclusion According to the results in this study,it demonstrated to strengthen the general vaccination,the screening and re-vaccination in kindergarten and school that were necessary,to ensure antibody levels in healthy population at high level.
