Using data from a community-based study of injection drug users (IDUs) in Sichuan Province in China, this study compared the level of HIV risk behavior (needle sharing and unsafe sex) amongst female and male IDUs, and examined the risk factors separately for these two groups. Five risk factors were examined in the analysis, including a lack of family support, having an IDU primary sex partner, ...

A seventh round behavioral and serological surveillance found that the HIV epidemic had remarkably increased to 7% among intravenous drug users (IDU) in Central Bangladesh, indicating the urgent need to increase prevention. The main purposes of this study were to find out, by collecting data and the necessary information from sero-surveillances, published reports, and articles, what the prevale...

BACKGROUND One major circulating HIV-1 subtype in Southeast Asian countries is CRF01_AE, but little is known about its epidemiology in Japan. We conducted a molecular phylodynamic study of patients newly diagnosed with CRF01_AE from 2003 to 2010. METHODS Plasma samples from patients registered in Japanese Drug Resistance HIV-1 Surveillance Network were analyzed for protease-reverse transcript...

Designing interventions to reduce HIV transmission among injecting drug users (IDU) requires reliable estimates of risk behaviors. We present population-based estimates for unsafe injection practices and sexual risk behaviors among male IDUs recruited through respondent driven sampling in India (Delhi: 783; Imphal: 766). IDUs in Delhi, mostly street-based (68%), reported injecting pharmaceutica...

We review evidence for effectiveness, cost-effectiveness, and coverage of antiretroviral therapy (ART) for injecting drug users (IDUs) infected with HIV, with particular attention to low-income and middle-income countries. In these countries, nearly half (47%) of all IDUs infected with HIV are in five nations--China, Vietnam, Russia, Ukraine, and Malaysia. In all five countries, IDU access to A...

INTRODUCTION AND AIMS Thailand's longstanding HIV epidemic among injection drug users (IDU) has been attributed, in part, to the Thai government's unwillingness to implement evidence-based HIV prevention interventions. This study was undertaken to examine risk factors for syringe borrowing among a community-recruited sample of Thai IDU. DESIGN AND METHODS We examined the prevalence of syringe...

OBJECTIVE To measure HIV prevalence and characterize associated risk behaviors among injection drug users (IDU) upon detention in Tehran, Iran. METHODS A cross-sectional survey included 459 male IDU arrested by police during a police sweep in Tehran in 2006. A questionnaire was completed, and blood was collected for HIV testing. RESULTS Overall HIV prevalence was 24.4% (95% confidence inter...

The present study aimed to describe the cognitive status of a group of HIV-positive asymptomatic intravenous drug users (IVDU) and changes which occurred over a 12-month follow-up period. Forty-two HIV positive IVDU were selected and matched for age, sex, educational level and pattern of drug abuse with 39 seronegative IVDU controls. Baseline and follow-up evaluation included neuropsychological...

OBJECTIVES To determine the demographic characteristics, risk behaviours and prevalence of HIV-1 among injection drug users (IDU) attending Calgary's needle exchange program (NEP). METHODS A survey was conducted from June through September 1998 among IDU attending Calgary's NEP. Demographic and behaviour characteristics were determined by personal interview and saliva was tested for HIV antib...

The purpose of this study was to produce models composed of mapping of connectivity networks of HIV transmission risk in injection drug users (IDUs). This methodology provided a novel approach and diagnostic tool for understanding HIV infection transmission risk and drug use in the typical niche of IDUs, i.e., a "shooting gallery" (a gathering site for injection drug activity). Furthermore, com...
