目的了解广西2008—2013年艾滋病的流行特征,为制定针对性预防控制措施提供科学依据。方法采用描述流行病学方法,分析广西2008—2013年艾滋病新发现病例资料。结果广西2008—2013年新发现HIV/AIDS报告数呈先升后降;疫情分布广泛,局部聚集。年龄主要为25~49岁,占53.49%,呈下降趋势;50岁以上逐年上升。男∶女为2.36∶1,其中15~24岁女性多于男性。职业分布以农民、家政、家务及待业为主。传播途径以性传播感染为主,其构成比从2008年的57.07%,逐年上升至2013年的95.79%;吸毒传播感染从2008年的24.46%逐年下降至2013年的3.30%。婚前检查、孕产期检查的HIV抗体阳性率逐年下降。晚发现比例从2008年的25.25%逐年上升至2013年的42.74%。结论广西艾滋病以性传播途径为主,2012、2013年艾滋病新发现病例数连续两年减少,晚发现比例增高。提示广西今后要进一步加强检测及早发现感染者,加强预防性传播为主的综合防制措施。
Objective To understand the epidemiological characteristics of AIDS in Guangxi from 2008 to 2013 and provide a scientific basis for the development of targeted prevention and control measures. Methods Descriptive epidemiological methods were used to analyze newly discovered HIV / AIDS cases in Guangxi during 2008-2013. Results The number of newly discovered HIV / AIDS cases in Guangxi in 2008-2013 increased first and then decreased; the epidemic was widely distributed and aggregated locally. The main age is 25 to 49 years old, accounting for 53.49%, showing a downward trend; over 50 years of age increased year by year. Male: Female 2.36: 1, of which 15 to 24-year-old women than men. Occupation distribution to farmers, housekeeping, housework and unemployed. The route of transmission was mainly sexually transmitted infections, which increased from 57.07% in 2008 to 95.79% in 2013 and from 24.46% in 2008 to 3.30% in 2013 respectively. Premarital examination, pregnancy test HIV antibody positive rate decreased year by year. The late discovery ratio increased from 25.25% in 2008 to 42.74% in 2013 year by year. Conclusion The main mode of AIDS transmission in Guangxi is sexually transmitted. The number of newly detected AIDS cases in 2012 and 2013 decreased for two consecutive years, with a higher proportion of late-onset AIDS cases. It is suggested that Guangxi should further strengthen the comprehensive prevention and control measures to detect and detect those infected as early as possible and strengthen prevention and transmission.
