自80年代初发现艾滋病以来.该病已在世界各地广泛流行,传播速度之快,波及范围之广令人震惊。为预防艾滋病,10年来不少国家和地区开展了血清学监测工作,查明了感染强度和流行特征,为确定预防和控制艾滋病的目标和策略提供了依据。1985年北京市发现我国第一例传入的艾滋病病例,提示这一严重的传染病已开始进入中国大门,为预防AIV传播,减少感染对人群的影响,我市从1987年就开始了艾滋病监测工作。1989年进一步制定艾滋病血清学监测计划,开展了北京地区高危人群和重点人群HIV感染监测研究课题。3年来从9985份血清标本中,查出感染者14人,其中中国人8人,外国人6人。通过对感染者的追访调查和管理,使我们掌握 Since the AIDS epidemic was discovered in the early 1980s, the disease has become widespread in various parts of the world and has spread alarmingly rapidly. In order to prevent AIDS, serological surveillance has been carried out in many countries and regions over the past 10 years, and the intensity and epidemic characteristics of infections have been identified. This has provided the basis for defining the goals and strategies for the prevention and control of AIDS. In 1985, Beijing discovered the first case of HIV transmission in China, suggesting that this serious epidemic has started to enter China. To prevent the spread of AIV and reduce the impact of infection on the population, the city started HIV surveillance in 1987 jobs. In 1989, further development of AIDS serology surveillance program, carried out in Beijing high-risk groups and key populations HIV infection monitoring research project. In 3 years, from 9985 serum samples, 14 people were found infected, including 8 Chinese and 6 foreigners. Through the follow-up investigation and management of those infected, we have to master
