80年代以来,我区甲型肝炎发病率波动在110.90/10万～500.00/10万之间,呈现出较高的发病水平,并先后出现了几次小范围的暴发。为了解我区甲型肝炎的流行趋势及其规律,我们于1988年7月开展了正常人群甲型肝炎抗体水平调查工作。方法随机抽取大富庄、北天堂、槐房、东风院、南顶村5个地区,共393人。采集肘静脉血3ml,分离血清后,低温保存,统一送北京市卫生防疫站病毒科检测。采用酶联免疫吸附试验检测甲型肝炎抗体IgG(下称甲肝抗体)。试剂由唐山市卫生防疫站提供药盒,批号880715。抑制率≥50%为阳性结果。结果丰台区正常人群甲肝抗体水平(表1)
Since the 1980s, the incidence of hepatitis A in our region has fluctuated between 110.90 / 100,000 and 500.00 / 100,000, showing a relatively high incidence and has appeared in several small-scale outbreaks. In order to understand the regional hepatitis A epidemic trends and its laws, we conducted in 1988 July the normal population of hepatitis A antibody levels survey. Methods A total of 393 people were randomly selected from Dafu Zhuang, Beitiantang, Huai Fang, Dongfengyuan and Nanding Village. Collect elbow venous blood 3ml, after separation of serum, cryopreservation, unified sent to Beijing Municipal Health and Epidemic Prevention Station virus detection. Hepatitis A antibody IgG (Hepatitis A antibody) was detected by enzyme-linked immunosorbent assay. Reagents by the Tangshan City Health and Epidemic Prevention Station to provide kit, batch number 880715. Inhibition rate ≥ 50% positive results. The results of normal population in Fengtai Hepatitis A antibody levels (Table 1)
