Diagnoses of HIV Infection in the United States and Dependent Areas, 2018: Gay, Bisexual, and Other Men Who Have Sex with Men

The Special Focus Profiles highlight trends and distribution of HIV in 5 populations of particular interest to HIV prevention programs in state and local health departments: (1) Transgender Persons, (2) Gay, Bisexual, and Other Men Who Have Sex With Men, (3) Persons Who Inject Drugs, (4) Women, and (5) Children Aged <13 Years.
Gay, bisexual, and other men who have sex with men (MSM) are the population most affected by HIV in the United States. Stigma, homophobia, and discrimination put MSM of all races/ethnicities at risk for multiple physical and mental health problems and can affect whether they seek and receive high-quality health services, including HIV testing, treatment, and other prevention services. In 2018, adult and adolescent MSM accounted for 69% (24,933 MSM and 1,372 MSM who also inject drugs) of the 37,968 new HIV diagnoses in the United States and 6 dependent areas. Many black/African American and Hispanic/Latino MSM with HIV, particularly young MSM, are unaware of their HIV infection. Lack of awareness of HIV status among young MSM may be due to recent infection, not getting testing due to underestimation of personal risk, or fewer opportunities to get tested. Persons who do not know they have HIV do not get medical care or receive treatment and can unknowingly infect others.

From 2014 through 2018 in the United States and 6 dependent areas, the largest number of diagnoses of HIV infection attributed to male-to-male sexual contact was among MSM aged 25–34 years (Figure 14). The number of diagnoses among MSM aged 25–34 years increased 6% (from 9,242 in 2014 to 9,760 in 2018) (Table 5b). From 2014 through 2018, the number of diagnoses among MSM aged 45–54 years decreased 22%, aged 13–24 years decreased 15%, and aged 35–44 years decreased 12%. The number of diagnoses among MSM aged 55 years and older remained stable.

a Hispanics/Latinos can be of any race.
From 2014 through 2018 in the United States and 6 dependent areas, HIV infection diagnoses increased 71% among Native Hawaiian/other Pacific Islander MSM (from 31 in 2014 to 53 in 2018). HIV infection diagnoses decreased 44% among MSM of multiple races (from 1,096 in 2014 to 610 in 2018) and decreased 16% among white MSM (from 7,630 in 2014 to 6,372 in 2018) (Figure 15 and Table 5b). The number of diagnoses among American Indian/Alaska Native, Asian, black/African American, and Hispanic/Latino MSM remained stable.

a Hispanics/Latinos can be of any race.
In 2018 in the United States and 6 dependent areas, black/African American MSM accounted for 25% (9,444) of the 37,968 HIV infection diagnoses and 38% of diagnoses (52% of MSM aged 13–24 years and 33% of MSM aged greater than 24 years) (Figure 16) among all MSM. Hispanic/Latino MSM made up 20% (7,653) of the 37,968 new HIV diagnoses. From 2014 through 2018 in the United States and 6 dependent areas, HIV diagnoses increased among Hispanic/Latino gay and bisexual men aged 25 years and older (Table 5b). Please use caution when interpreting data for American Indian/Alaska Native and Native Hawaiian/other Pacific Islander MSM: the numbers are small.

a Hispanics/Latinos can be of any race.
In 2018 in the United States and 6 dependent areas, the South had more diagnoses of HIV infection (12,540) among MSM than any other region and accounted for 50% of all diagnoses of HIV infection among MSM (Figure 17). The largest percentage of MSM with HIV infection diagnoses in the South was among blacks/African Americans (48%), followed by Hispanics/Latinos (26%), and whites (23%). The largest percentage of MSM with HIV infection diagnoses in the West was among Hispanics/Latinos (46%), followed by whites (29%), and blacks/African Americans (16%). The largest percentage of MSM with HIV infection diagnoses in the Northeast was among Hispanics/Latinos (35%), followed by blacks/African Americans (34%) and whites (24%). The largest percentage of MSM with HIV infection diagnoses in the Midwest was among blacks/African Americans (45%), followed by whites (34%), and Hispanics/Latinos (16%). MSM of multiple races, and American Indian/Alaska Native, Asian, and Native Hawaiian/other Pacific Islander MSM combined accounted for less than 10 percent of all diagnoses of HIV infection among MSM in any region.
Prevalence and Race/Ethnicity
At the end of 2018 in the United States and 6 dependent areas, 576,787 MSM were living with diagnosed HIV infection. Approximately 37% of MSM living with diagnosed HIV infection were white, 31% were black/African American, and 25% were Hispanic/Latino. Males of multiple races accounted for 5% of MSM living with diagnosed HIV infection, Asians accounted for 2%, and American Indians/Alaska Natives and Native Hawaiians/other Pacific Islanders each accounted for less than 1% (Table 15b).

Transmission category is the term for the classification of cases that summarizes an adult’s or adolescent’s possible HIV risk factors; the summary classification results from selecting, from the presumed hierarchical order of probability, the 1 (single) risk factor most likely to have been responsible for transmission. For surveillance purposes, a diagnosis of HIV infection is counted only once in the hierarchy of transmission categories [7]. Adults or adolescents with more than 1 reported risk factor for HIV infection are classified in the transmission category listed first in the hierarchy. The exception is men who had sexual contact with other men and injected drugs; this group makes up a separate transmission category.
Hierarchical Categories:
- Male-to-male sexual contact: men who have had sexual contact with men (i.e., homosexual contact) and men who have had sexual contact with both men and women (i.e., bisexual contact)
- Injection drug use (IDU): persons who have injected non-prescription drugs
- Male-to-male sexual contact and injection drug use (male-to-male sexual contact and IDU): men who have had sexual contact with other men and injected non-prescription drugs
- Heterosexual contact: persons who have ever had heterosexual contact with a person known to have, or to be at high risk for, HIV infection
- Perinatal: persons infected through perinatal transmission but aged 13 years and older at time of diagnosis of HIV infection. Prevalence data and tables of death data includes persons infected through perinatal transmission but aged 13 years and older during the specified year or at death.
- Other: all other transmission categories (e.g., blood transfusion, hemophilia, risk factor not reported or not identified).
Cases of HIV infection reported without a risk factor listed in the hierarchy of transmission categories are classified as “no identified risk (NIR).” Cases classified as NIR include cases that are being followed up by local health department staff; cases in persons whose risk-factor information is missing because they died, declined to be interviewed, or were lost to follow-up; and cases in persons who were interviewed or for whom other follow-up information was available but for whom no risk factor was identified.
Because a substantial proportion of cases of HIV infection are reported to CDC without an identified risk factor, multiple imputation is used to assign a transmission category to these cases [7]. Multiple imputation is a statistical approach in which each missing transmission category is replaced with a set of plausible values that represent the uncertainty about the true, but missing, value [8]. Each resulting data set containing the plausible values is analyzed by using standard procedures, and the results from these analyses are then combined to produce the final results. In tables displaying transmission categories, multiple imputation was used for adults and adolescents, but not for children (because the number of cases in children is small, missing transmission categories were not imputed).
In the Federal Register [6] for October 30, 1997, the Office of Management and Budget (OMB) announced the Revisions to the Standards for the Classification of Federal Data on Race and Ethnicity. Implementation by January 1, 2003 was mandated. At a minimum, data on the following race categories should be collected:
- American Indian or Alaska Native
- Asian
- black or African American
- Native Hawaiian or other Pacific Islander
- white
Additionally, systems must be able to retain information when multiple race categories are reported. In addition to data on race, data on 2 categories of ethnicity should be collected:
- Hispanic or Latino
- not Hispanic or Latino
The Asian or Pacific Islander category displayed in annual surveillance reports published prior to the 2007 surveillance report was split into 2 categories: (1) Asian and (2) Native Hawaiian or other Pacific Islander. The Asian category (in tables where footnoted) includes the cases in Asians/Pacific Islanders (referred to as legacy cases) that were reported before the implementation of the new race categories in 2003 (e.g., cases of HIV infection that were diagnosed and reported to CDC before 2003 but that were classified as stage 3 [AIDS] after 2003) and a small percentage of cases that were reported after 2003 but that were reported according to the old race category (Asian/ Pacific Islander). In tables of diagnoses of HIV infection during 2014–2018, the Asian category does not include Asian/Pacific Islander cases because these cases were diagnosed after 2003 and were reported to CDC in accordance with OMB’s Revisions to the Standards for the Classification of Federal Data on Race and Ethnicity [6].
This report also presents data for persons for whom multiple race categories are reported. In this report, persons categorized by race were not Hispanic or Latino. The number of persons reported in each race category may, however, include persons whose ethnicity was not reported.
The data in this report include information received by CDC through December 31, 2019. The data are organized into 2 sections: National Profile and Special Focus Profiles. For both the National and Special Focus Profiles, figures are presented. For the National Profile, tables are presented in the Tables section in 2 formats. Tables in the first format—labeled “a”—exclude data from the dependent areas (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, the Republic of Palau, and the U.S. Virgin Islands). Tables in the second format—labeled “b”—include data from the dependent areas.
Please use caution when interpreting numbers less than 12, and rates and trends based on these numbers.
Data by region reflect the address at the time of diagnosis of HIV infection for figures and tables that present number of diagnoses (Figures 17, 19, 24; Tables 1a/b–7a/b). For tables presenting prevalence data (14a/b–17a/b), region is based on most recent known address as of the end of the specified year. For the death tables (10a/b–13a/b), region is based on residence at death. When information on residence at death is not available, the state where a person’s death occurred is used.

The 4 regions of residence and 6 dependent areas used in this report are defined by the U.S. Census Bureau as follows:
- Northeast: Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont
- Midwest: Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin
- South: Alabama, Arkansas, Delaware, District of Columbia (D.C.), Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, Virginia, and West Virginia
