1. HIV Surveillance in Men Who Have Sex with Men (MSM)
For all slides in this series, the following notes apply:
Estimated numbers and rates of diagnoses of HIV infection are based on data from 46 states and 5 U.S. dependent areas that have had confidential name-based HIV infection reporting for a sufficient length of time (i.e., implemented in area since at least January 2007 and reported to CDC since at least June 2007) to allow for stabilization of data collection and for adjustment of the data in order to monitor trends.
Estimated numbers and rates of AIDS diagnoses are based on data from the 50 states, the District of Columbia, and 6 U.S. dependent areas. For the first time, the Republic of Palau has been included in numbers and rates of AIDS diagnoses, deaths, and persons living with AIDS.
Rates are not calculated by race/ethnicity for the 6 U.S. dependent areas because the U.S. Census Bureau does not collect information from all U.S. dependent areas.
At the time of development of this slide series, complete 2010 census data were not available from the U.S. Census Bureau. Therefore, all U.S. population estimates and denominators used to calculate rates were based on the official postcensus estimates for 2009.

2. This slide presents the distribution of diagnoses of HIV infection among adult and adolescent males diagnosed from 2007 through 2010, by transmission category, for 46 states and 5 U.S. dependent areas with long-term confidential name-based HIV infection reporting.
The estimated number of diagnoses of HIV infection among adult and adolescent males exposed through male-to-male sexual contact increased by 10% from 26,578 in 2007 to 29,194 in During 2007 through 2010, the number of diagnoses of HIV infection among adult and adolescent males exposed through heterosexual contact decreased by 8% (from 5,034 in 2007 to 4,630 in 2010); among males exposed through injection drug use, diagnoses decreased by 24% (from 3,417 in 2007 to 2,581 in 2010); and among males exposed through male-to-male sexual contact and injection drug use, diagnoses decreased by 19% (from 1,817 in 2007 to 1,474 in 2010).
The remaining diagnoses of HIV infection were those attributed to hemophilia or the receipt of blood or blood products, and those in persons without an identified risk-factor.
The following 46 states have had laws or regulations requiring confidential name-based HIV infection reporting since at least January 2007 (and reporting to CDC since at least June 2007): Alabama, Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Virginia, Washington, West Virginia, Wisconsin, and Wyoming.

Heterosexual contact is with a person known to have, or to be at high risk for, HIV infection.

3. In 2010, an estimated 77.0% (29,194) of all diagnosed HIV infections among adult and adolescent males were attributed to male-to-male sexual contact. Heterosexual contact was the second largest transmission category among males, at 12.2% of diagnosed HIV infections.

4. The racial/ethnic distribution of diagnoses of HIV infection among adult and adolescent men who have sex with men (MSM) has changed over time in the 46 states and 5 U.S. dependent areas with long-term confidential name-based HIV infection reporting. From 2007 through 2010, the estimated percentage of diagnoses of HIV infection in white MSM decreased from 39% to 36% of diagnoses among MSM, while the percentage of diagnoses of HIV infection in black/African American MSM increased from 34% to 37%. The percentage of diagnoses of HIV infection in black/African American MSM exceeded the percentage of diagnoses in white MSM for the first time in 2009.
The percentage of Hispanic/Latino MSM diagnosed with HIV infection remained stable during this time (approximately 23% of diagnoses among MSM).
The percentages of diagnoses of HIV infection in American Indian/Alaska Native, Asian, and Native Hawaiian/other Pacific Islander MSM, as well as MSM of multiple races are small, but have remained stable from

Most (77%) diagnoses of HIV infection in adults and adolescents were in males. Among males diagnosed with HIV infection from , 75% were attributed to male-to-male sexual contact. The percentage of diagnosed HIV infections attributed to male-to-male sexual contact was even larger (89%) among males aged 13 to 24 years.

Of all MSM aged 13–24 years diagnosed with HIV infection in 2009, an estimated 58% were black/African American, followed by Hispanics/Latinos (20%) and whites (19%).

13. The bars in this graph represent the estimated number of AIDS diagnoses by year in the United States and 6 U.S. dependent areas during 1985–2010 among adult and adolescent men who have sex with men (MSM). The number of AIDS diagnoses among MSM peaked in 1992 and steadily decreased until AIDS diagnoses among MSM have remained relatively stable since that time.
The line in this graph represents the percentage of all diagnosed AIDS cases among adults and adolescents that were attributed to male-to-male sexual contact. In 1985, MSM accounted for 65% of cases, but by 1998, MSM accounted for 40% of cases. In 2010, MSM accounted for 50% of all AIDS diagnoses among adults and adolescents.
All displayed data are estimates. Estimated numbers resulted from statistical adjustment that accounted for reporting delays and missing risk-factor information, but not for incomplete reporting.
Data exclude men who reported sexual contact with other men and injection drug use.

14. The upper line represents the estimated number of AIDS diagnoses in the United States and 6 U.S. dependent areas during 1985–2009 among adult and adolescent men who have sex with men (MSM). The lower line represents the estimated number of deaths among the same group during the same period.
The peak in AIDS diagnoses among MSM during 1992–1993 was associated with the expansion of the AIDS surveillance case definition, which was implemented in January 1993.
Among MSM, the overall decline in new AIDS diagnoses and deaths is due in part to the success of highly active antiretroviral therapy, which became widely available during the mid-1990s.
All displayed data are estimates. Estimated numbers resulted from statistical adjustment that accounted for reporting delays and missing risk-factor information, but not for incomplete reporting. Deaths of persons with an AIDS diagnosis may be due to any cause.
Data exclude men who reported sexual contact with other men and injection drug use.

15. This graph shows the racial/ethnic trends in estimated AIDS diagnoses in the United States and 6 U.S. dependent areas during 1985–2010 among adult and adolescent men who have sex with men (MSM). Rates by race and ethnicity, important for understanding the impact of the epidemic on racial/ethnic groups, are not presented due to the difficulty in obtaining the total number of MSM in each race/ethnicity category.
Noteworthy is the decline from 1992 through 2001 in AIDS diagnoses among white MSM. Despite this decline, the largest number of AIDS diagnoses each year from 1985 through 2009 was among white MSM. In 2010, the number of AIDS diagnoses among black/African American MSM (6,239) exceeded that of white MSM (6,096) for the first time.
Although there were smaller numbers of AIDS diagnoses in blacks/African Americans, Hispanics/Latinos, persons of multiple races, American Indians/Alaska Natives and Native Hawaiians/other Pacific Islanders than among whites, the rates of AIDS diagnoses in the general population of males were higher for these races/ethnicities, so it is likely that the rates would be higher for MSM of these races/ethnicities.
