The Tanzania HIV Impact Survey 2016-2017 (THIS) is a nationally representative, cross-sectional, population-based survey of households across the United Republic of Tanzania.
It focused on measuring key biological endpoints to provide direct estimates of HIV risk and burden, and of the effectiveness and population-level impact of HIV-related prevention, care, and treatment interventions implemented in the country.
THIS is the first national survey to conduct these measurements in Tanzania. The survey also collected information on behaviors associated with HIV acquisition and transmission, common HIV co-morbidities, and other health conditions.
