The Community Vulnerability and Responses to Drug-User-Related HIV/AIDS, 1990-2013 [96 Metropolitan Statistical Areas, United States] study (CVAR) was a research study of why large United States Metropolitan Statistical Areas (MSAs) vary over time in their vulnerability to HIV/AIDS among drug users and in MSA responses to HIV/AIDS. This collection contains estimates of HIV prevalence among people who injected drugs (PWID) and among sub-populations of PWID. This collection is comprised of ten datasets with differing amounts of variables and provides trend data that describe the following:

  • Epidemiologic outcomes including population prevalence of PWIDs and Non-injecting drug users (NIDUs), and particularly their prevalence among youth; and, among PWIDs, HIV prevalence, late-diagnosis HIV cases, and AIDS incidence and mortality.
  • Implementation of evidence-based drug-related interventions including drug abuse treatment, syringe exchange, HIV counseling and testing.
  • Implementation of non-evidence-based drug-related interventions including incarceration and arrests of drug users.

The collection contains data on the MSA sub-populations including Black, Hispanic, White and "other" race categories. In addition, some statistics are presented in age range categories such as ages 15-29, 30-64 and 15-64.

Transmission Reduction Intervention Project (TRIP), Athens, Greece Site, 2013-2015 (ICPSR 39059)

Released/updated on: 2025-09-22
Geographic coverage: Athens, Greece
Time period: 2013-06-01--2015-07-01
Half or more of HIV transmission events may occur within the period of high infectivity (and often high risk behavior) that can last 11 months or more after a person is initially infected. The study sought to develop effective intervention techniques against HIV transmission during the recent infection period using a combination of injection-, sexual- and social-network-based contact tracing methods; community alerts in the networks and venues of recent infectees; and the logic of going "up" and "down" infection chains. The investigators' first aim was to develop and evaluate ways to locate "seeds", defined as drug users and other people who have recently been infected. The investigators' second aim targeted members of seeds' networks and people who attend their venues. The investigators tested them for acute and for recent infection, and alerted them to the probability that their networks contain highly-infectious members so they should reduce their risk and transmission behaviors for the next several months to minimize their chances of getting infected. This may also reduce transmission by untested people with recent infection. Community, network and venue education about the need and value of supporting those with recent infection should reduce stigma. The investigators' third aim was to reduce HIV transmission and to develop new ways to evaluate "prevention for positives" generally as well as the investigators own success in reducing transmission. The investigators did this using a combination of follow-up interviews and testing, including of viral loads; phylogenetic techniques; and discrete event simulation modeling to assess the investigators effectiveness.
