During 2001-2006, new human immunodeficiency virus (HIV) diagnoses among black men aged 13-24 years who have sex with men (MSM) in 33 states increased by 93%. The Wisconsin Division of Public Health (WDPH) recently reported to CDC a 144% increase during 2000-2008 in HIV diagnoses among black MSM aged 15-29 years in Milwaukee County. In October 2009, the City of Milwaukee Health Department (MHD), WDPH, and CDC investigated whether the increase in HIV infections among young black MSM in Milwaukee represented increased HIV transmission or simply better identification of prevalent infections. This report describes the results of that investigation, which indicated that a new "social networks" HIV testing strategy and the recent expansion of better targeted HIV testing efforts accounted for few diagnoses among young black MSM and occurred after HIV diagnoses increased, respectively. Therefore, although some diagnoses were made because of intensified testing, an increase in HIV transmission likely occurred. Moreover, an increase in syphilis diagnoses among young black MSM in Milwaukee preceded the increase in HIV diagnoses, which suggests that changes in risk behavior or sexual networks might explain the increase. These findings highlight the need for new or improved interventions promoting prevention education, early HIV detection, and entry to care for young HIV-infected and at-risk black MSM in Milwaukee.
2001 至 2006 年期间，33 个州与男性发生性关系的 13-24 岁黑人男性新艾滋病毒（HIV）诊断病例增加了 93%。威斯康星州公共卫生部（WDPH）最近向疾病预防控制中心报告，2000 至 2008 年期间，密尔沃基县 15-29 岁黑人男男性行为者（MSM）中 HIV 诊断病例增加了 144%。2009 年 10 月，密尔沃基市卫生部门（MHD）、WDPH 和疾病预防控制中心调查了密尔沃基年轻黑人 MSM 中 HIV 感染的增加是否代表 HIV 传播的增加或只是更普遍的感染。本报告介绍了该调查的结果，表明新的“社交网络”HIV 检测策略和最近扩大的更有针对性的 HIV 检测工作，分别导致了少数年轻黑人 MSM 的诊断，且发生在 HIV 诊断增加之后。因此，尽管一些诊断是由于强化检测所致，但 HIV 传播的增加很可能已经发生。此外，密尔沃基年轻黑人 MSM 中梅毒诊断的增加先于 HIV 诊断的增加，这表明风险行为或性网络的变化可能解释了这一增加。这些发现强调需要新的或改进的干预措施，以促进预防教育、早期 HIV 检测以及密尔沃基年轻 HIV 感染者和高危黑人 MSM 进入护理。
