The Transmission Reduction Intervention Project (TRIP) is an HIV tracing intervention which prioritizes newly infected individuals and their social networks. According to a study co-authored by CHAS Fellow John Schneider: “If a person recruited by TRIP has recently acquired HIV, it is likely that the person who infected him/her, others whom that infector may recruit, and those whom the index person has infected are located in the same network.” By this logic, TRIP is able to identify more individuals who have been recently infected and are highly contagious than tracing interventions which do not prioritize based on infection duration. The study found TRIP to have “significantly higher yields,” suggesting that current efforts to seek, test, and treat can be accelerated through network-based approaches.
