This bar chart shows the number of new HIV infections in 2010 for the most-affected sub-populations. The most new infections occurred among white men who have sex with men, or MSM, (11,200) followed by black MSM (10,600), Hispanic MSM (6,700), black heterosexual women (5,300), black heterosexual men (2,700), white heterosexual women (1,300), Hispanic heterosexual women (1,200), black male injection drug users, or IDU, (1,100) and black female IDU (850).

The latest CDC estimates of new HIV infections (HIV incidence) in the United States indicate that HIV remains a serious health problem, with an estimated 47,500 people becoming newly infected with the virus in the United States in 2010. HIV incidence has remained relatively stable at about 50,000 infections per year since the mid-1990s in the United States. Certain groups, including African Americans, Latinos and gay and bisexual men of all races/ethnicities, continue to be disproportionately affected by HIV.

 

This pie chart shows the estimated percentage of new HIV infections by transmission category, 2010. The largest percentage of new HIV infections occurred among men who have sex with men, or MSM, (63%) followed by heterosexuals (25%), injection drug use, or IDU, (8%) and MSM-IDU (3%).

Men who have sex with men (MSM) remain the group most heavily affected by HIV in the United States. CDC estimates that MSM accounted for nearly two-thirds (63 percent) of all new infections in 2010 (29,800). Heterosexuals accounted for 25 percent of estimated new HIV infections in 2010 (12,100). Injection drug users (IDUs) represented 8 percent of estimated new HIV infections in 2010 (3,900).

 

This bar chart shows the estimated number of new HIV infections among men who have sex with men (MSM) aged 13-24, 2008-2010. From 2008-2010, there was a 22% increase in new HIV infections from 7,200 in 2008 to 8,800 in 2010.

The number of new infections among the youngest MSM (aged 13-24) increased 22 percent, from 7,200 infections in 2008 to 8,800 in 2010. Young black MSM continue to bear the heaviest burden, accounting for more than half (55 percent) of new infections among young MSM (4,800) – and for more new infections than any other subgroup.

 

This chart shows the estimated number of new HIV infections among heterosexuals by gender and race/ethnicity, 2010. There were a total of 12,100 new infections among heterosexuals, with 4,100 infections among males and 8,000 among females. Among males, black males accounted for 2,700 new infections, followed by Hispanic males (780) and white males (620). Among females, black females accounted for 5,300 new infections, followed by Hispanic females (1,200) and white females (1,300).

Heterosexuals accounted for 25 percent of estimated new HIV infections in 2010 (12,100). About two-thirds (66 percent) of those infected through heterosexual sex were women.

 

This graph shows that in the US in 2010, the rate of new HIV infections among black males was 103.6 cases per 100,000 population, the rate for Hispanic males was 45.5 cases per 100,000 population, and the rate for white males was 15.8 cases per 100,000 population. The rate among black females was 38.1 cases per 100,000 population, the rate for Hispanic females was 8.0 cases per 100,000 population, and the rate among white women was 1.9 cases per 100,000 population.

CDC´s new estimates show that African Americans, more than any other racial/ethnic group, continue to bear the greatest burden of HIV in the United States. The overall HIV infection rate among blacks was almost eight times higher than that of whites (68.9 v. 8.7 per 100,000 of the population). Hispanics also continue to be disproportionately affected by HIV. The HIV infection rate among Hispanics was three times that of whites (27.5 v. 8.7 per 100,000). Whites accounted for nearly a third (31 percent) of all new HIV infections in 2010 (14,900), but had a substantially lower HIV infection rate (8.7 per 100,000) than African Americans or Hispanics.

 

This bar chart shows the estimated number of new HIV infections among black women, 2008-2010. From 2008-2010, there was a 21% decrease in new infections among black women – from 7,700 infections in 2008 and 6,100 in 2010

Black women accounted for 13 percent of all new HIV infections in the United States in 2010 and nearly two-thirds (64 percent) of all new infections among women. Most black women (87 percent) were infected through heterosexual sex. While new infections among black women remain high, for the first time this analysis found indications of an encouraging decline. Between 2008 and 2010, new HIV infections among black women decreased 21 percent, from 7,700 in 2008 to 6,100 in 2010. Additional years of data will be needed to determine if the decrease among black women is the beginning of a longer-term trend.

 

This line graph shows the HIV prevalence and incidence for 1982-2010. Currently, 1.1 million people are living with HIV in the U.S. (an estimated 1,148,200 adults and adolescents). About 50,000 new HIV infections have occurred in the U.S. each year since the mid-1990s, down from a peak of roughly 130,000 in the mid-1980s.

Although persisting at far too high a level (approximately 50,000 infections per year), HIV incidence has been reduced by more than two-thirds since the height of the U.S. HIV epidemic, and HIV prevention efforts are estimated to have averted more than 350,000 HIV infections in the United States to date. Additionally, despite continued increases in the number of people living with HIV over the past decade (about 1.1 million people living with HIV today), new HIV infections have not increased, indicating that HIV testing, prevention, and treatment programs are effectively reducing the rate of transmission overall.
