Limited Interaction Targeted Epidemiology: Epidemiology of Transmission and Treatment of HIV Among People Who Are at Increased Risk for HIV Infection in Latin America (LITE-LA) (UG3/UH3 Clinical Trial Optional)

The purpose of this notice of funding opportunity (NOFO) is to support investigators who will form large, electronically-generated cohorts in Latin America of HIV-negative men who have sex with men (MSM), transgender women (TGW), people who inject drugs (PWID), and/or female sex-workers and follow them to study the epidemiology of HIV incidence. Continued follow-up of those persons who acquire HIV will be required to study the epidemiology of viral suppression. Comparisons of participants by seroconverstion status will provide information on geographic and socially defined areas of high HIV incidence as well as on both personal and structural vulnerabilities to HIV infection. Among participants who seroconvert, comparisons of those becoming rapidly engaged in care and who reach non-detectable HIV levels to those whose virus remains detectable will inform on the treatment of HIV in Latin American countries. This NOFO will allow digital trials to determine optimal study approaches, or to pilot evidence-based digital (mHealth and online) HIV prevention and treatment interventions to both reduce HIV incidence and improve treatment in the most vulnerable populations.
