OBJECTIVE To examine hepatitis C virus (HCV) seroprevalence among injection drug users in 4 US cities from 1994 through 2004. METHODS Demographic characteristics, behaviors, and prevalence of HCV antibody among 5088 injection drug users aged 18-40 years from Baltimore, Maryland; Chicago, Illinois; Los Angeles, California; and New York, New York, enrolled(More)
BACKGROUND The yield of nucleic acid amplification testing (NAAT) after routine screening for human immunodeficiency virus (HIV) antibody to detect acute HIV infection (AHI) may vary with different HIV-antibody assays. METHODS From April 24, 2006, through March 28, 2008, patients underwent routine HIV-antibody screening using a first-generation assay at(More)
BACKGROUND The prevalence and correlates of rectal sexually transmitted infections are well described among men who report receptive anal intercourse (AI); however, little is known about the epidemiology of rectal sexually transmitted infections among women. METHODS We conducted a cross-sectional study of women attending public sexually transmitted(More)
BACKGROUND Given the strong relation between sexually transmitted diseases (STDs) and the spread of HIV infection, recent outbreaks of syphilis in the United States could lead to increased rates of new HIV infection. STD clinics serving persons at risk for syphilis would be logical sites to monitor rates of acute HIV infection. The detection of acute HIV(More)
OBJECTIVES A high incidence of HIV continues among men who have sex with men (MSM) in industrialised nations and research indicates many MSM do not disclose their HIV status to sex partners. Themes as to why MSM attending sexually transmitted infection (STI) clinics in Los Angeles and Seattle do and do not disclose their HIV status are identified. METHODS(More)
OBJECTIVES We examined the relation between childhood sexual abuse and injection drug use initiation among young adult injection drug users. METHODS We used mixed effect linear models to compare age at first injection among 2143 young injection drug users by first sexual abuse age categories. RESULTS The participants were predominantly male (63.3%) and(More)
OBJECTIVE To evaluate acceptance of confidential HIV antibody testing and reasons for test refusal among heterosexual clients of Los Angeles County sexually transmitted disease (STD) clinics. METHODS From January 1993 through June 1994, all blood specimens routinely collected for syphilis serology were tested blindly for HIV antibody at seven STD clinics.(More)
BACKGROUND Injection drug users (IDUs) and their sex partners account for an increasing proportion of new AIDS and HIV cases in the United States, but public debate and policy regarding the effectiveness of various HIV prevention programs for them must cite data from other countries, from non-street-recruited IDUs already in treatment, or other programs,(More)
BACKGROUND Detection of acute HIV infection (AHI) with pooled nucleic acid amplification testing (NAAT) following HIV testing is feasible. However, cost-effectiveness analyses to guide policy around AHI screening are lacking; particularly after more sensitive third-generation antibody screening and rapid testing. METHODS AND FINDINGS We conducted a(More)
