Results: Based on 3,096,729 HIV-infected person-years, the overall HIV case-fatality rate was 20.6/1,000 person-years (95% confidence interval [CI], 20.3–20.9). Ageadjusted rates by state ranged from 9.6 (95% CI 6.8–12.4) in Idaho to 32.9 (95% CI 29.8–36.0) in Mississippi, demonstrating significant differences across states, even after adjusting for race/ethnicity (p<0.0001).
