2008-2020年重庆市巴南区学生艾滋病病毒感染者和病人流行病学特征分析

The Epidemiological Characteristics of Students With HIV/AIDS in Banan District of Chongqing From 2008 to 2020

目的分析巴南区92例学生HIV/AIDS病例的流行病学特征,为制定学生人群艾滋病防控策略提供依据。方法在中国疾病预防控制信息系统传染病监测子系统中的艾滋病防治基本信息模块中筛选出现住址为巴南区且职业为学生的HIV/AIDS病例的信息数据,采用描述性流行病学方法对其流行病学特征进行分析。结果巴南区92例学生HIV/AIDS病例中,男性90例、女性2例,报告时平均年龄为19.82±3.87岁,以20~岁组(52.17%)、汉族(97.83%)、大专及以上文化程度(81.52%)、现住址城区(80.90%)及区内户籍(52.17%)人群所占构成比最大。艾滋病自愿咨询检测(VCT)是学生病例发现的主要途径(48.91%);同性性传播是主要的感染方式(81.52%)。经性传播途径感染的学生,在最后一次高危性行为发生后10 d内来检测的占57.30%;在确诊后10 d内完成CD4+T淋巴细胞检测的占43.82%;首次CD4+T淋巴细胞检测结果>500个/μl的占24.72%,5例学生首次CD4+T淋巴细胞检测即被诊断为艾滋病;半年内开始抗病毒治疗的有69.66%。结论男男同性性传播是巴南区学生感染艾滋病的主要方式,已报告的学生病例存在抗病毒治疗开始时间晚的情况。应加强针对性防控措施的落实,尤其减少学生同性性传播艾滋病病例的发生。
