The mass provision of HIV treatment in rural KwaZulu-Natal, South Africa has raised adult life expectancy by 18 years since 2003. We will conduct a population-based survey to assess young adults' beliefs about HIV, HIV treatment, and expectations for the future in the era of mass HIV treatment. Thh investigators will conduct a randomized evaluation to assess whether a short video providing young adults with information on longevity gains from HIV treatment affects young adults survival expectations, hope for the future, and health and educational behaviours, including uptake of HIV testing and treatment services, the study's primary outcome.
