The Scope and Impact of HIV in the United States

New Infections and Overall Burden

Since the height of the epidemic in the mid-1980s, the annual number of new HIV infections in the United States has been reduced by more than two-thirds, from roughly 130,000 to 50,000 annually.2 As a result of treatment advances since the late 1990s, the number of people living with HIV (HIV prevalence) has increased dramatically.1 Yet, despite increasing HIV prevalence and more opportunities for HIV transmission, the number of new infections has been relatively stable since the mid-1990s.2

HIV Prevalence and New Infections, 1980-2011
This graph shows the HIV prevalence from 1980 to 2011 and new infections in the United States, from 1980 to 2010. The number of people living with HIV has climbed steadily in this period, with the exception of 1989 - 1995, when there was a plateau around 700,000 cases. There were fewer than 100,000 individuals living with HIV in 1980, and approximately 1.2 million in 2011. Three methodologies were used to estimate new cases of HIV: from 1980 through 2004, new infections were estimated using back-calculation methodology; in 2007, new HIV infections were calculated using the original incidence surveillance methodology; and from 2007 through 2010, new HIV infections were calculated using an updated incidence surveillance methodology. New HIV infections peaked in 1984 and 1985 approximately 130,000 and are now roughly stable at approximately 50,000. (Download High Resolution Version)

Heavily Affected Subgroups

U.S. Subpopulations with the Largest Numbers of Estimated New HIV Infections, 2010
This bar chart shows estimated new HIV infections in 2009 by race/ethnicity, risk group, and gender for the most-affected subpopulations in the United States. Gay and bisexual men of all races and black heterosexual women and men account for the greatest number of new HIV infections in the United States. Specifically, the chart shows that there were: 11,200 infections among white men who have sex with men (MSM); 10,600 infections among black MSM; 6,700 infections among Hispanic MSM; 5,300 infections among black heterosexual women; 2,700 infections among black heterosexual men; 1,300 infections among white heterosexual women; 1,200 infections among Hispanic heterosexual women; 1,100 infections among black male injection drug users (IDUs); 850 infections among black female IDUs; 780 new infections among Hispanic heterosexual men.

By transmission category, the largest number of new HIV infections currently occurs among men who have sex with men (MSM) of all races and ethnicities, followed by African American heterosexual women. By race/ ethnicity overall, African Americans are the most heavily affected, followed by Latinos.2

Geography of the U.S. Epidemic

HIV Diagnoses, 2013
This graphic shows a map of the United States divided into 4 regions.  The overall national number of new HIV diagnoses in 2013 was 47,352, a rate of 15.0 per 100,000 people.  In the Northeast Region, there were 8,908 HIV cases, a rate of 15.9 per 100,000 people.  In the South Region, there were 24,323 HIV cases, a rate of 20.5 per 100,000 people.  In the West Region, there were 8,013 HIV cases, a rate of 10.8 per 100,000 people. In the Midwest Region, there were 6,109 HIV cases, a rate of 9.0 per 100,000 people.

Recent data on HIV diagnosis make it clear that HIV touches every corner of United States. According to these data, by region, the number of people diagnosed with HIV and the of HIV diagnoses (number of diagnoses per 100,000 people) is highest in the South (24,323 diagnoses or 20.5 per 100,000 people). Next highest is the Northeast (8,908; 15.9), followed by the West (8,013; 10.8) and the Midwest (6,109; 9.0).

From 2009 to 2013, the rate of HIV diagnoses in the West decreased, and the rates in the Northeast, Midwest, and South remained stable.

HIV remains mainly an urban disease, with the majority of individuals diagnosed with HIV in 2013 residing in areas with 500,000 or more people. Areas hardest hit (by ranking of HIV cases per 100,000 people) include Atlanta, GA; Miami, FL; Washington DC; Baton Rouge and New Orleans, LA; Memphis, TN and Baltimore, MD.3
