目的了解1992~2015年潍坊市艾滋病疫情特征及变化趋势,为今后预防控制艾滋病提供科学依据。方法对1992~2015年报告的潍坊市辖区内的艾滋病病毒感染者/艾滋病病人(HIV/AIDS)流行病学资料进行分层分析。结果截止2015年底,潍坊市累计报告HIV感染者/AIDS病人672例。根据历年报告例数和增长幅度,划分了4个流行阶段,分别为散发期(1992~2004年)、快速播散期(2005~2009年)、持续增长期(2010~2012年)和快速增长期(2013~2015年),男男性传播病例构成比从散发期的7.14%(1/14)增长到快速增长期的64.29%(243/378),是增长最快的传播途径。不同流行阶段病例的人口学特征、传播途径和样本来源差异均有统计学意义(P<0.01)。结论潍坊市疫情形势严峻,以性途径传播为主,MSM人群是潍坊市艾滋病流行的主要高危人群。
Objective To understand the characteristics and trends of AIDS epidemics in Weifang from 1992 to 2015 and provide a scientific basis for the future prevention and control of AIDS. Methods The epidemiological data of HIV / AIDS from 1992 to 2015 in Weifang were analyzed by stratified analysis. Results By the end of 2015, 672 HIV / AIDS patients had been reported by Weifang City. According to the number of reports and the growth rate over the years, four popular periods are defined, which are distribution period (1992-2004), period of rapid dissemination (2005-2009), growing period (2010-2012) and rapid growth (2013-2015), the proportion of MSM cases increased from 7.14% (1/14) in the distribution period to 64.29% (243/378) in the rapid growth period, which was the fastest growing route of transmission. There were significant differences in demographic characteristics, route of transmission and sample source in different epidemic stages (P <0.01). Conclusion The situation of epidemic in Weifang is serious and mainly spread by sex. The MSM population is the main high-risk population of AIDS in Weifang.
