Rates of estimated diagnoses of HIV infection, rates of people living with HIV, and rates of P&S syphilis were higher among MSM than among other men or women (Tables ​4-​6). The rate ratios indicate disparities between MSM and other men and MSM and women. Comparing MSM to other men, the estimated rate of diagnoses of HIV infection in 2008 was 59 to 75 times as high (Table ​4), the estimated rate of MSM living with a diagnosis of HIV infection was 38 to 48 times as high (Table ​5), and the P&S syphilis diagnosis rate was 63 to 79 times as high (Table ​6).
