PrEP your step: Implementing an online crowdsourcing contest to engage young people in HIV prevention in Washington DC, USA.

HIV incidence among young people (Black and Latinx women and men who have sex with men ages 16-24 years), in the United States is high. Traditional top-down approaches for pre-exposure prophylaxis (PrEP) social marketing are not effectively reaching this population. Crowdsourcing is a promising approach to engaging young people in the development of innovative solutions to raise awareness and use of PrEP among those at highest risk of HIV.
