2014年广西晚发现HIV/AIDS病例的流行病学特征

Epidemiological characteristics of late diagnosed HIV/AIDS cases of 2014 in Guangxi

目的了解2014年广西新报告的艾滋病病毒(HIV)感染者和艾滋病(AIDS)病人(简称HIV/AIDS病人)中,晚发现病例的流行病学特征,为防控策略制定提供依据。方法利用艾滋病综合防治信息系统的数据,采用描述性流行病学方法,对2014年广西艾滋病晚发现病例的流行病学特征进行分析。结果 2014年广西新报告HIV/AIDS病人9526例,其中晚发现病例4926例(51.71%)。不同流行病学特征病例的晚发现比例的差异有统计学意义,其中男性、离异或丧偶、农民、异性性传播感染和样本来自临床就诊的病例晚发现比例较高,分别为56.66%(3878/6844)、60.05%(1096/1825)、55.24%(3787/6855)、53.37%(4722/8847)和59.30%(3342/5636)。结论 2014年广西HIV/AIDS病人晚发现比例较高,应加强主动监测力度,扩大对高危和重点人群的宣传和检测,从而及早发现感染病例,降低晚发现比例。

Objective To explore epidemiological characteristics of individuals with late HIV diagnosis in newly reported cases of 2014,and provide data evidence for intervention strategies in Guangxi.Methods Data of 2014 new HIV cases were extracted retrospectively from Guangxi HIV/AIDS surveillance system.Descriptive analysis method was used to make statistical analysis.Results Among 9,526 newly reported HIV/AIDS cases of 2014 in Guangxi,51.71% of them were diagnosed late.Differences amid late diagnosis of such cases with variable epidemiological characteristics show statistical significance.Higher rate of late diagnosis occurred in the male group,divorced or single persons,farmers,cases via heterosexual transmission and clinical patients.The late diagnosis of these groups occupied respectively 56.66%（3878/6844）,60.05%（1096/1825）,55.24%（3787/6855）,53.37%（4722/8847）and59.30%（3342/5636）.Conclusion Late HIV diagnosis of 2014 newly reported cases in Guangxi was high.Strategies are required for enhancing HIV/AIDS surveillance,as well as accelerate counseling and testing in high risk and key populations,so as to early discover more HIV/AIDS cases,and reducing the rate of late diagnosis.
