HIV in the United States: At A Glance
CDC estimates that 1,144,500 persons aged 13 years and older are living with HIV infection, including 180,900 (15.8%) who are unaware of their infection1. Over the past decade, the number of people living with HIV has increased, while the annual number of new HIV infections has remained relatively stable. Still, the pace of new infections continues at far too high a level— particularly among certain groups.
HIV Incidence (new infections): The estimated incidence of HIV has remained stable overall in recent years, at about 50,000 new HIV infections per year2. Within the overall estimates, however, some groups are affected more than others. MSM continue to bear the greatest burden of HIV infection, and among races/ethnicities, African Americans continue to be disproportionately affected.
HIV Diagnoses (new diagnoses, regardless of when infection occurred): In 2011, an estimated 49,273 people were diagnosed with HIV infection in the United States. In that same year, an estimated 32,052 people were diagnosed with AIDS. Overall, an estimated 1,155,792 people in the United States have been diagnosed with AIDS3.
Deaths: An estimated 15,529 people with an AIDS diagnosis died in 2010, and approximately 636,000 people in the United States with an AIDS diagnosis have overall3. The deaths of persons with an AIDS diagnosis can be due to any cause—that is, the death may or may not be related to AIDS.
By Risk Group
Gay, bisexual, and other men who have sex with men (MSM) of all races and ethnicities remain the population most profoundly affected by HIV.
In 2010, the estimated number of new HIV infections among MSM was 29,800, a significant 12% increase from the 26,700 new infections among MSM in 20082.
Although MSM represent about 4% of the male population in the United States4, in 2010, MSM accounted for 78% of new HIV infections among males and 63% of all new infections2. MSM accounted for 52% of all people living with HIV infection in 2009, the most recent year these data are available1.
In 2010, white MSM continued to account for the largest number of new HIV infections (11,200), by transmission category, followed closely by black MSM (10,600)2.
The estimated number of new HIV infections was greatest among MSM in the youngest age group. In 2010, the greatest number of new HIV infections (4,800) among MSM occurred in young black/African American MSM aged 13–24. Young black MSM accounted for 45% of new HIV infections among black MSM and 55% of new HIV infections among young MSM overall2.
Since the epidemic began, an estimated 302,148 MSM with an AIDS diagnosis have died, including an estimated 5,909 in 20103.
