Project dates: August 2012 - July 2019
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 will seek to develop effective intervention techniques against HIV transmission among drug users and their community members during the recent infection period. It will evaluate ways to locate individuals who have been recently infected, and of finding members within their drug-using and other social networks and venues. This group will be tested for acute and for recent infection, alerted to the probability that their networks contain highly-infectious members, and educated in ways to minimize their chances of getting infected. In addition, the project will develop and evaluate ways to reduce stigmatization of those newly-infected with HIV.Abstract on NIH RePORTER
