HIV prevalence rates among African-Americans were about eight times that of whites. HIV prevalence rates for Hispanics or Latinos were about 2.5 times that of whites.
Among other key findings:
- People between ages 13 and 24 have the highest percentage of undiagnosed HIV, at 58.9%, compared to 31.5% for people aged 25-34, 18% among people 34-44, 13.8% for people 45-54, 11.9% for people 55-64, and 10.7% among people 65 and older.
- Greater percentages of undiagnosed HIV also were found among men with high-risk heterosexual contact, 25%, and men who have sex with men, 22.1%, than in other categories.
- Greater percentages of undiagnosed HIV also were observed among Asians or Pacific Islanders at 26% and American Indians or Alaska Natives at 25% than among African-Americans at 21.4%, whites at 18.5%, and Hispanics or Latinos at 18.9%.
Testing can now detect HIV as early as nine days after infection.
Highly active antiretroviral therapy has been effective in allowing people to live longer with HIV.
However, late diagnosis is all too common. In 2008, the CDC says 33% of newly diagnosed HIV cases developed AIDS within a year. These people were likely infected with HIV 10 years prior to the diagnosis, on average. During this time period, they missed opportunities for medical care.
Frieden says in the news release that far too many Americans still underestimate their risk of infection or think HIV is no longer a serious health threat. But he says it is imperative that Americans understand that HIV is incurable and that most infections today are occurring among people under 30, a generation “that has never known a time without effective HIV treatments and who may not fully understand the significant health threat HIV poses.”
He says that advances in HIV prevention hold promise for reducing new infection.
