Abstract

There were 1311 newly diagnosed HIV cases in San Francisco between 2005 and 2011 that were linked to care at publicly funded facilities and had viral sequences available for analysis. Of the 214 cases characterized as recently infected with HIV at the time of diagnosis, 25% had a recent sexually transmitted infection diagnosis (vs. 10% among longer-standing HIV infections, P < 0.001) and 57% were part of a phylogenetic transmission cluster (vs. 42% among longer-standing HIV infection, P < 0.001). The association observed between recent HIV infection and having a sexually transmitted infection diagnosis during the interval overlapping likely HIV acquisition points to potential opportunities to interrupt HIV transmission.

摘要

2005年至2011年间,旧金山有1311例新诊断的HIV病例,这些病例与公共资助机构的护理相关联,并且有病毒序列可供分析。在诊断时被确定为近期感染HIV的214例病例中,25%近期有性传播感染诊断(而在长期感染HIV的病例中这一比例为10%,P<0.001),57%属于系统发育传播簇(而在长期感染HIV的病例中这一比例为42%,P<0.001)。在可能感染HIV的重叠时间段内,近期HIV感染与有性传播感染诊断之间的关联表明存在中断HIV传播的潜在机会。
