Listen up New Yorkers. HIV is spreading in the city at nearly three times the national rate, according to the CDC. Gay men of color are the most vulnerable group. From the NY Times: "The findings, based on a new formula developed by the federal Centers for Disease Control and Prevention, estimated that 4,762 New Yorkers contracted H.I.V. in 2006, the most precise estimate the city had ever offered. But the city stressed that because the method of estimating infections was new, it could not be said definitively whether the number of new infections in the city had increased or decreased from previous years. Blacks, and men who have sex with other men, are particularly the groups at greatest risk of contracting H.I.V., the study found."
