Preventing HIV Transmission by Recently Infected Drug Users

Principal Investigator: Samuel R. Friedman

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. Unfortunately, neither test-and-treat intervention methods nor Acute HIV Infection projects have found effective ways to intervene against transmission during this risky "recent infection" period. We seek to develop effective intervention techniques against HIV transmission among drug users and their community members during the recent infection period using a combination of drug 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.
