PurposeThe purpose of this paper is to review the literature on information and communication technologies (ICTs), development and trust and to introduce papers in the special issue: “Trust and information and communication technologies for development”.Design/methodology/approachThe paper reviews the literature on trust, broadly, and then, specifically, focuses on linkages to ICTs, and human development.FindingsTrust is a broadly defined, yet relatively understudied concept in the context of ICTs and development (ICTD). The paper finds that there are many definitions of trust and ways it is constituted in the context of ICTD. It highlights the opportunity to contribute to the literature and this burgeoning field through research on trust in ICT‐mediated services or systems, trust in information and trust in institutions that are often key providers of these services.Originality/valueThe paper holds value to both academics and practitioners working in the field of ICTD by outlining the key programmatic areas in which research on this topic can be applied.

The purpose of this study was to characterize the injection and sexual risk behaviors of a cohort of active drug injectors who have initiated injection within the past 4 years and to compare their behaviors with the risk behaviors of long-term injectors who have been injecting drugs since 1984. A stratified, network-based sample was used to recruit injection drug users from the streets in Miami-Dade, Florida. After screening for eligibility, which included a urine test to confirm current drug use, participants were administered a structured questionnaire that included basic demographic information, drug-use history, and HIV risk behavior practices. Both injector groups displayed a high level of HIV injection risk behavior. Although new initiates into injection demonstrated lower risk behavior than long-term injectors at the first injection episode, the current risk behavior between new and long-term injectors is similar.

The purpose of this paper is to estimate HIV seroprevalence and to examine the injection and sexual risk behaviours of a cohort of active new heroin injectors who have initiated injection within the past four years and to compare their risk behaviours with those of long-term heroin injectors who initiated injection prior to January 1, 1985. A stratified network-based sample was used to recruit injection drug users (IDUs) from the streets of Miami-Dade, Florida. New IDUs displayed a significantly lower HIV seroprevalence than long-term injectors (13.3 versus 24.7%). Both new and long-term drug injectors exhibited a high level of current HIV risk behaviour. While new injectors were more likely than long-term injectors to practise safer injection behaviours at the initial injection episode, the current risk behaviours of new and long-term injectors are similar.
