目的：了解来陕西地区就诊的人类免疫缺陷病毒/ 艾滋病（Human immunodeficiency virus/Acquired immuno deficiency syndrome，HIV/AIDS）患者感染状况、流行特征。方法：收集来我院就诊的HIV/AIDS 患者的基本信息，对其流行病学资料统计分析。结果：在调查的1225 例HIV/AIDS患者中，男性占83.51%，平均年龄为（35.55± 11.61）岁，50.98%为农民，小学及以下学历占 33.55%，经血液途径感染250 例，经性传播途径感染916 例，其中同性性传播337 例，经母婴垂直传播16 例，就诊时CD4+T 淋巴细胞计数平均值为（222.82± 190.49）个/uL，56%的HIV/AIDS 患者采用的抗病毒方案为齐多夫定（Zidovudine, AZT）/ 替诺福韦（Tenofovir Disoproxil Fumarate，TDF）+拉米夫定（Lamivudine，3TC）+依非韦伦（Efavirenz，EFV）方案。结论：陕西地区HIV/AIDS 感染人数呈上升趋势，且年轻化加剧，同性性传播比例大幅增加。虽然治疗较为及时，应进一步在高危人群中积极宣传防艾知识与措施。
