To examine the quality of HIV sero-surveillance systems in countries by 2002, as well as trends between 1995 and 2002.
The quality of countries' surveillance systems was scored for five years: 1995, 1997, 1999, 2001, and 2002. Sero-surveillance data were compiled from the US Census Bureau's HIV/AIDS Surveillance Database, the EuroHIV database, and from countries' national HIV surveillance reports that were available to WHO/UNAIDS. The quality of systems was scored according to the level of the countries' epidemic.
There has been a large variation in the quality of HIV surveillance systems across the 132 countries by type of the epidemic and over time from 1995 to 2002. Over the 1995-2002 period the number of countries with a fully implemented system decreased from 57 (43%) in 1995 to 48 (36%) in 2002. The proportion of countries with a fully implemented system was 58%, 34%, and 10% in countries with a generalised, concentrated, and low level epidemic, respectively. In the 53 countries with generalised epidemics the number of countries with a fully implemented system increased from 24 (45%) in 2001 to 31 (58%) in 2002.
Many countries still have poor functioning HIV surveillance systems and require urgent strengthening. Countries should monitor and evaluate their own HIV surveillance systems and examine whether the systems are appropriate and adequate.
评估截至2002年各国艾滋病毒血清学监测系统的质量，以及1995年至2002年期间的变化趋势。
对各国监测系统在1995年、1997年、1999年、2001年和2002年这五年的质量进行评分。血清学监测数据来自美国人口普查局的艾滋病毒/艾滋病监测数据库、欧洲艾滋病毒数据库以及世界卫生组织/联合国艾滋病规划署可获取的各国国家艾滋病毒监测报告。根据各国的疫情水平对系统质量进行评分。
1995年至2002年期间，132个国家的艾滋病毒监测系统质量因疫情类型和时间不同存在很大差异。在1995 - 2002年期间，全面实施监测系统的国家数量从1995年的57个（43%）降至2002年的48个（36%）。在疫情广泛流行、集中流行和低水平流行的国家中，全面实施监测系统的国家比例分别为58%、34%和10%。在53个疫情广泛流行的国家中，全面实施监测系统的国家数量从2001年的24个（45%）增至2002年的31个（58%）。
许多国家的艾滋病毒监测系统仍运转不佳，急需加强。各国应监测和评估本国的艾滋病毒监测系统，检查这些系统是否恰当和充分。
