Figure 10F In 2011, among adults and adolescents diagnosed with HIV infection in the United States and 6 dependent areas, an estimated 62% of all diagnosed infections were attributed to male-to-male sexual contact.  Less than 1% of diagnosed infections were attributed to other transmission categories. CDC	Figure 10G Comparison of the estimated rates of diagnoses of HIV infection between males and females by race/ethnicity in the US. In 2011, blacks/African Americans accounted for the highest rates of diagnoses of HIV infection for males (112.8 per 100,000 population) and for females (40.0 per 100,000 population). CDC	Figure 10H In 2011, among adult and adolescent males diagnosed with HIV infection in the US, an estimated 78% of infections were attributed to male-to-male sexual contact.    Among adult and adolescent females, 86% of diagnosed HIV infections were attributed to heterosexual contact, 14% were attributed to injection drug use, and less than 1% to other transmission categories. CDC	Figure 10I From 2008 through 2011, the largest percentage of diagnoses of HIV infection each year in the US was for blacks/African Americans. In 2011, the percentages of diagnoses were 46% for blacks/African Americans, 28% for whites, 22% for Hispanics/Latinos, 2% each for Asians and persons of multiple races, and less than 1% each for American Indians/Alaska Natives and Native Hawaiians/other Pacific Islanders. CDC	Figure 10J In 2011, among the 39,495 diagnoses of HIV infection among adult and adolescent males in the US, 42% were black/African American, 30% were white, and 23% were Hispanic/Latino.   Among the 10,512 diagnoses among adult and adolescent females in 2011, 63% were black/African American, 17% were Hispanic/Latino, and 17% were white.

Figure 10J Numbers and percentages of diagnoses of HIV infection in 2011 by transmission category, in the US. Of the 50,007 HIV infections diagnosed in 2011 among adults and adolescents, approximately 62% were attributed to male-to-male sexual contact. An additional 3% of diagnosed infections were attributed to male-to-male sexual contact and injection drug use. CDC	Figure 10K In 2011, an estimated 30,896 diagnosed HIV infections in US were attributed to male-to-male sexual contact. Of these, an estimated 38% were among blacks/African Americans, 34% were among whites, and 24% were among Hispanics/Latinos. Approximately 2% each were among Asians and persons reporting multiple races. American Indians/Alaska Natives and Native Hawaiians/other Pacific Islanders accounted for less than 1% of diagnosed infections each. CDC	Figure 10L In 2011, an estimated 13,801 diagnosed HIV infections in the US were attributed to heterosexual contact.   Overall, approximately two-thirds of diagnosed HIV infections attributed to heterosexual contact were among blacks/African Americans (65%). HIV infection attributed to heterosexual contact when separated by sex also shows approximately 65% of both males and females were black/African American. Whites accounted for 11% of infections for males and 15% for females. Hispanics/Latinos accounted for 21% of infections for males and 17% for females. CDC	Figure 10M In 2011, an estimated 1,423 diagnosed HIV infections in the United States were attributed to male-to-male sexual contact and injection drug use.   The majority of diagnosed HIV infections attributed to male-to-male sexual contact and injection drug use were among whites (44%). Blacks/African Americans accounted for approximately 31% and Hispanics/Latinos accounted for 21% of diagnosed infections. Asians and males of multiple races each accounted for 2% of infections. American Indians/Alaska Natives accounted for 1% and Native Hawaiians/other Pacific Islanders accounted for less than 1% of infections. CDC	Figure 10N In 2011, an estimated 3,836 diagnosed HIV infections in the United States were attributed to injection drug use.   Overall, nearly half of the diagnosed HIV infections attributed to injection drug use were among blacks/African Americans (47%). When separated by sex, 46% of males and 49% of females were black/African American. Whites accounted for 21% of infections for males and 30% for females. Hispanics/Latinos accounted for 30% of infections for males and 17% for females.  Persons of multiple races accounted for approximately 1% of diagnosed infections for males and 2% for females. Asians accounted for approximately 1% each for both males and females. American Indians/Alaska Natives and Native Hawaiians/other Pacific Islanders accounted for 1% or less each for both males and females. CDC
