OBJECTIVE To estimate HIV incidence in the United States using a newly developed method. METHODS The analysis period (2002-2011) was broken down into 3-year periods with overlaps, and HIV incidence was estimated based on the relationship between number of new diagnoses and HIV incidence in each of these 3-year periods, by assuming that all HIV infections(More)
CONTEXT Incidence of human immunodeficiency virus (HIV) in the United States has not been directly measured. New assays that differentiate recent vs long-standing HIV infections allow improved estimation of HIV incidence. OBJECTIVE To estimate HIV incidence in the United States. DESIGN, SETTING, AND PATIENTS Remnant diagnostic serum specimens from(More)
Data are limited regarding cancer risk in human immunodeficiency virus (HIV)-infected persons with modest immunosuppression, before the onset of acquired immunodeficiency syndrome (AIDS). For some cancers, risk may be affected by highly active antiretroviral therapy (HAART) widely available since 1996. We linked HIV/AIDS and cancer registries in Colorado,(More)
BACKGROUND Effective antiretroviral therapy has reduced the risk of AIDS and dramatically prolonged the survival of HIV-infected people in the United States. Consequently, an increasing number of HIV-infected people are at risk of non-AIDS-defining cancers that typically occur at older ages. We estimated the annual number of cancers in the HIV-infected(More)
IMPORTANCE Early diagnosis of human immunodeficiency virus (HIV) infection, prompt linkage to and sustained care, and antiretroviral therapy are associated with reduced individual morbidity, mortality, and transmission of the virus. However, levels of these indicators may differ among population groups with HIV. Disparities in care and treatment may(More)
Objective: In preparation for jointly publishing official government cancer statistics, the Centers for Disease Control and Prevention (CDC) and the National Cancer Institute (NCI) compared incidence rates from NCI's Surveillance Epidemiology and End Results (SEER) program and CDC's National Program of Cancer Registries (NPCR). Methods: Data for 1999(More)
OBJECTIVE To determine the distribution of HIV-1 subtypes and the prevalence of transmitted drug resistance-associated mutations (TDRM) among persons newly diagnosed with HIV-1 infection in the United States. METHODS We used sequence data from Variant, Atypical, and Resistant HIV Surveillance (VARHS) collected from newly diagnosed persons in 10 states and(More)
IMPORTANCE Human immunodeficiency virus (HIV) transmission risk is primarily dependent on behavior (sexual and injection drug use) and HIV viral load. National goals emphasize maximizing coverage along the HIV care continuum, but the effect on HIV prevention is unknown. OBJECTIVES To estimate the rate and number of HIV transmissions attributable to(More)
In the United States, an estimated 1.2 million persons are living with human immunodeficiency virus (HIV), a serious infection that, if untreated, leads to illness and premature death. Persons living with HIV who use antiretroviral therapy (ART) and achieve very low levels of the virus (suppressed viral load) can have a nearly normal life expectancy 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)
