摘　　要：2021年5月18日,Z省P市X区疾病预防控制中心接到公安分局一起涉嫌故意传播艾滋病案件的协查通知,对涉案人员王某和赵某开展流行病学溯源调查。王某,男性,于2019年确证HIV阳性。赵某,男性,在王某未告知感染HIV的情况下,2021年3月期间与之发生多次无保护性行为。3月28日,赵某出现发热、咽痛等症状,5月11日经P市疾控中心确证为HIV抗体阳性。在与王某发生性行为前后,赵某未与他人发生过性行为,未发现手术史、输血史、吸毒史等其他HIV暴露史。经Z省疾控中心实验室检测,赵某与王某样本的HIV核酸序列具有高度同源性。综合流行病学调查、实验室检测结果和公安部门收集的证据,王某在未告知HIV感染的情况下与赵某发生无保护肛交性行为,导致赵某感染HIV,判定王某故意传播艾滋病。On 18 May 2021,the Center for Disease Control and Prevention(CDC)of X District in P City,Z Province received a co-investigation of a suspected case of intentional HIV transmission from the public security branch,and con⁃ducted epidemiological investigations on Zhao and Wang(both males).Wang was confirmed HIV-positive in 2019.Zhao had unprotected sexual encounters several times with Wang in March 2021 without being informed of Wang's HIV infec⁃tion.Zhao developed fever,sore throat and other symptoms of acute infection phase on 28 March,and were confirmed HIV positive by the CDC of P City on 11 May.Zhao did not have sex with anyone else before or after having sex with Wang.In addition,Zhao had no history of surgery,blood transfusions,drug use or any other history of HIV exposure.Laboratory tests conducted by the CDC of Z Province showed that the HIV nucleic acid sequences between the samples of Zhao and Wang had a high degree of homology.Combined with the epidemiological investigation,laboratory testing and the evidence from the public security branch,it was concluded that Wang intentionally transmitted HIV to Zhao through unprotected anal sex without disclosing his HIV infection status.
