The Intensive Combination Approach to Rollback the HIV Epidemic in Nigeria (iCARE, Nigeria), is funded by the United States National Institutes of Health (NIH) to develop and evaluate interventions to improve HIV testing and linkage, and HIV care outcomes, among youth (age 15-24 years) in Nigeria, using theoretically-grounded peer navigation and mHealth components. Currently being piloted in Ibadan, this multicenter research is anticipated to extend to six clinical research sites in Lagos and Jos, in the last quarter of 2020.
