Abstract

We examined perceived serosorting of injection paraphernalia sharing networks among a sample of 572 injection drug users (IDUs). There was evidence for serosorting of high-risk injection behaviors among HIV-negative IDUs, as 94% of HIV-negative IDUs shared injection paraphernalia exclusively with perceived HIV-negative networks. However, 82% of HIV-positive IDUs shared injection paraphernalia with perceived HIV-negative networks. The findings indicate a potential risk of rapid HIV transmission. Future prevention efforts targeting IDUs should address the limitation of serosorting, and focus on preventing injection paraphernalia sharing regardless of potential sharing networks' perceived HIV status.

摘要

我们在对 572 名注射吸毒者(IDU)的样本进行调查时,研究了他们对注射用具共享网络的血清分类感知。在 HIV 阴性 IDU 中,存在高风险注射行为的血清分类现象,因为 94%的 HIV 阴性 IDU 仅与感知的 HIV 阴性网络共享注射用具。然而,82%的 HIV 阳性 IDU 与感知的 HIV 阴性网络共享注射用具。这些发现表明存在 HIV 快速传播的潜在风险。未来针对 IDU 的预防工作应解决血清分类的局限性,并注重防止无论潜在共享网络的 HIV 状况如何,都要共享注射用具。
