The rate ratios illustrate disparities by race/ethnicity. Comparing black male PWID to white male PWID, the estimated rate of diagnoses of HIV infection was 7–29 times as high (Table S2) and the estimated rate of living with a diagnosis of HIV infection was 9–38 times as high (Table S3); comparing Hispanic/Latino to white male PWID, these rates were 4–17 and 5–20 times as high, respectively (Tables S2 and S3). Comparing black female PWID to white female PWID, the estimated rate of diagnosis of HIV infection was 5–29 times as high (Table S2) and the estimated rate of living with a diagnosis of HIV infection was 6–42 times as high (Table S3); comparing Hispanic/Latino to white female PWID, these rates were 3–8 and 4–12 times as high, respectively (Tables S2 and S3). By age, the rate of PWID living with a diagnosis of HIV was higher among older age groups than those 13–24 years for males and for females (Table S2).
