BACKGROUND Hispanic subgroups of varied national origin differ culturally; overall, Hispanics in the United States are disproportionately affected by HIV infection. METHODS We analyzed cases of HIV infection that were diagnosed among Hispanics in 33 states and US-dependent areas during 2003-2006 and reported to the Centers for Disease Control and(More)
OBJECTIVES We examined HIV diagnosis rates and disease progression among men who have sex with men (MSM) according to race/ethnicity and age. METHODS Using data obtained from the national HIV/AIDS surveillance system, we examined trends in HIV diagnosis rates for 2001 through 2004 using Poisson regression. We used a standardized Kaplan-Meier method to(More)
BACKGROUND In the United States, Hispanics are disproportionately affected by HIV infection. However, Hispanic subgroups of varied national origin differ culturally and HIV may impact them differently. METHODS We used information on Hispanics/Latinos diagnosed with HIV during 2006-2009 in 40 states and Puerto Rico, and aged ≥13 years, reported to the(More)
In carcinomas such as those of breast, pancreas, stomach, and colon, cancer cells support the expansion of molecular and cellular stroma in a phenomenon termed desmoplasia, which is characterized by a strong fibrotic response. In the case of breast tissue, in which stroma is mainly a fatty tissue, this response presumably occurs at the expense of the(More)
OBJECTIVES In the United States a growing proportion of cases of heterosexually acquired HIV infections occur in women and in persons of color. We analyzed the association between race/ethnicity, whether diagnoses of HIV infection and AIDS were made concurrently, and the survival after diagnosis of heterosexually acquired AIDS. METHODS We used data from(More)
BACKGROUND We examined durable viral suppression, cumulative viral load (VL) burden, and transmission risk potential among human immunodeficiency virus (HIV)-diagnosed persons in care. METHODS Using data from the National HIV Surveillance System from 17 jurisdictions with complete reporting of VL test results, we determined the percentage of persons in(More)
The population at the U.S.-Mexico border has experienced growth, more than double the U.S. national average. Movements of populations in this region have contributed to increased incidence of certain infectious diseases. We used information on persons diagnosed with HIV during 2003 to 2006 and aged 13 years or older (n = 4,279) reported to the Centers for(More)
OBJECTIVE The goal of this study was to examine associations between demographic, behavioral, and clinical variables and mother-to-child HIV transmission in 15 US jurisdictions for birth years 2005 through 2008. METHODS The study used Enhanced Perinatal Surveillance system data for HIV-infected women who gave birth to live infants. Multivariable logistic(More)
The objective of the study was to characterize human immunodeficiency virus (HIV)-seropositive pregnant adolescents according to maternal reproductive, behavioral, and psychosocial characteristics. Data were derived from the national HIV/AIDS Reporting System (HARS, 2001-2004) and the Perinatal Guidelines Evaluation Project (PGEP, 1997-1999). Births to(More)
BACKGROUND While the U.S. HIV epidemic continues to be primarily concentrated in urban area, local epidemiologic profiles may differ and require different approaches in prevention and treatment efforts. We describe the epidemiology of HIV in large urban areas with the highest HIV burden. METHODS/PRINCIPAL FINDINGS We used data from national HIV(More)
