Geographic Differences in HIV Infection in Hispanics
Geographic Differences in HIV Infection in Hispanics
In the United States, Hispanics or Latinos are disproportionately affected by infection with human immunodeficiency virus (HIV). In 2010, new diagnoses of HIV infection among Hispanics or Latinos occurred at an annual rate that was 2.8 times that of non-Hispanic whites (20.4 versus 7.3 per 100,000 persons). To further assess HIV infection among Hispanics or Latinos in the United States, CDC analyzed the geographic distribution of new diagnoses in 2010 in 46 states and Puerto Rico and the characteristics of those diagnosed. The results of this analysis determined that a lower percentage of infections were attributed to male-to-male sexual contact in Puerto Rico than in the 46 states (36.1% versus 66.5%) and a higher percentage were attributed to heterosexual contact (40.7% versus 22.0%) or injection-drug use (IDU) (20.4% versus 8.6%). In the 46 states, the rate of new diagnoses of HIV infection among Hispanics or Latinos in the Northeast Census region in 2010 (55.0 per 100,000 persons) was more than twice as high as in other regions, and a higher percentage of those with a new HIV diagnosis were born in Puerto Rico or had their HIV infection attributed to IDU, compared with other regions. Geographic differences in HIV infection among Hispanics or Latinos should be addressed with HIV testing, prevention, and treatment efforts tailored to specific communities.
Data were analyzed for Hispanics or Latinos* with newly diagnosed HIV infection in 2010 who were aged ≥13 years at HIV diagnosis and for those living with a diagnosis of HIV infection who were aged ≥13 years at the end of 2009. The data were reported to CDC through June 2011 by Puerto Rico, which represented 98.1% of Hispanics or Latinos diagnosed with HIV infection in five U.S. dependent areas in 2010, and the 46 states. All of these reporting areas have had confidential, name-based HIV infection reporting since at least January 2007. The numbers and percentages of HIV diagnoses in 2010 among Hispanic or Latino adolescents and adults in each U.S. Census region and Puerto Rico were calculated by sex, age group, transmission category, residence at diagnosis, and place of birth. The number of diagnoses of HIV infection was adjusted for reporting delay but not for incomplete reporting. Multiple imputation was used to assign a transmission category to those cases missing risk information. The number of persons living with a diagnosis of HIV infection (prevalence of diagnosed HIV infection) was further adjusted to account for the delay in reporting of deaths among persons with HIV. Where possible, rates per 100,000 persons were calculated based on postcensal estimates of Hispanic populations from the U.S. Census Bureau.

Introduction
In the United States, Hispanics or Latinos are disproportionately affected by infection with human immunodeficiency virus (HIV). In 2010, new diagnoses of HIV infection among Hispanics or Latinos occurred at an annual rate that was 2.8 times that of non-Hispanic whites (20.4 versus 7.3 per 100,000 persons). To further assess HIV infection among Hispanics or Latinos in the United States, CDC analyzed the geographic distribution of new diagnoses in 2010 in 46 states and Puerto Rico and the characteristics of those diagnosed. The results of this analysis determined that a lower percentage of infections were attributed to male-to-male sexual contact in Puerto Rico than in the 46 states (36.1% versus 66.5%) and a higher percentage were attributed to heterosexual contact (40.7% versus 22.0%) or injection-drug use (IDU) (20.4% versus 8.6%). In the 46 states, the rate of new diagnoses of HIV infection among Hispanics or Latinos in the Northeast Census region in 2010 (55.0 per 100,000 persons) was more than twice as high as in other regions, and a higher percentage of those with a new HIV diagnosis were born in Puerto Rico or had their HIV infection attributed to IDU, compared with other regions. Geographic differences in HIV infection among Hispanics or Latinos should be addressed with HIV testing, prevention, and treatment efforts tailored to specific communities.
Data were analyzed for Hispanics or Latinos* with newly diagnosed HIV infection in 2010 who were aged ≥13 years at HIV diagnosis and for those living with a diagnosis of HIV infection who were aged ≥13 years at the end of 2009.
