目的：介绍2007年估计艾滋病风险和感染者人数的方法。设计：估计工作在2007年进行，由国家艾滋病和性传播疾病控制和预防中心领导，联合国艾滋病和世界卫生组织合作。方法：工作簿方法用于处理地市和县级监测数据，以生成每个地市按风险组划分的艾滋病流行率，然后将其导入频谱模型，以生成新感染和艾滋病毒相关死亡的估计值。工作组估计，截至2007年，中国有70万艾滋病毒/艾滋病感染者，当年有5万新感染者和2万与艾滋病毒有关的死亡。注射吸毒和性接触仍然是艾滋病毒传播的主要方式，异性接触迅速成为主要途径，占2007年新感染病例的44.7%。艾滋病毒/艾滋病的流行仍然高度集中在某些地区，与广泛的变化，在患病率跨regions.Conclusions：2007年的估计是基于最准确的和地方一级的数据，迄今为止，包括病例报告，哨点监测数据，从大规模筛选的关键目标群体的结果，和特殊的流行病学研究。
Objective: To present the methods used for the 2007 estimates for the number of people at risk for and infected with HIV.Design: Estimation work took place throughout 2007, led by the National Center for AIDS and Sexually Transmitted Disease Control and Prevention in collaboration with United Nations AIDS and the World Health Organization.Methods: The workbook method was used to process prefecture and county-level surveillance data to generate HIV prevalence by risk group for each prefecture, which was in turn imported into the spectrum model to generate estimates of new infections and HIV-related deaths.Results: The working group estimated that as of 2007, there were 700,000 people living with HIV/AIDS in China, with 50,000 new infections and 20,000 HIV-related deaths in that year. Injection drug use and sexual contact are still primary modes of HIV transmission, with heterosexual contact quickly becoming the dominant route, making up 44.7% of new infections in 2007. The HIV/AIDS epidemic is still highly concentrated in certain areas, with wide variation in prevalence across regions.Conclusions: The 2007 estimates are based on the most accurate and local-level data available to date, including case reports, sentinel surveillance data, results from mass screening of key target groups, and special epidemiological studies.
