Background: An estimated 50,000 people are newly infected with human immunodeficiency virus (HIV) each year in the United States and in 2009, men who have sex with men (MSM) accounted for an estimated 61% of new infections. STD clinics serve large numbers of MSM and information on new HIV diagnoses is important to describe the HIV epidemic and help plan future healthcare needs.

Objectives: To calculate the annual number of new HIV diagnoses among MSM attending STD Surveillance Network (SSuN) STD clinics

Methods: SSuN is a sentinel surveillance system comprised of 12 health departments that follow similar protocols for the collection of demographic, risk behavior, and clinical data on all patients attending participating STD clinics. Men reporting ever having sex with men were classified as MSM. Only STD clinics with >50 MSM were included in this analysis. We reviewed STD clinic data collected on all MSM tested for HIV in 30 of 41 STD clinics for one year (July 1, 2010 through June 30, 2011).

Results: There were 31,170 visits representing 18,339 unique MSM not known to be previously HIV-positive and 73% (n=13,501) had one or more HIV test. Of those tested, 22% (n=2928) were tested =2 times (range 2-8). There were 718 new HIV diagnoses during the observation period (median, 5 cases/100 MSM); the range by clinic was 0-18 /100 MSM. MSM who tested HIV-positive were significantly more likely to be under age 29 (OR, 1.3[95%CI, 1.1-1.5]) and African-American (OR, 3.7[95%CI, 3.1-4.5]) as compared to Whites

Conclusions: Overall 5% of MSM attending STD clinics were newly diagnosed with HIV. STD clinics serve as an important healthcare setting to identify HIV infections and serve as a primary source of HIV screening among some MSM.

Implications for Programs, Policy, and Research: This analysis demonstrates the importance of STD clinics and the critical role they play in HIV case-finding among MSM.
