The Malawi Population-Based HIV Impact Assessment (MPHIA) was a nationally representative, crosssectional population-based survey of households across Malawi.
MPHIA focused on measuring key biological endpoints to provide direct estimates of HIV-infection risk and burden, and of the effectiveness and population-level impact of the prevention, care, and treatment interventions implemented in the country.
MPHIA is the first national survey to conduct these measurements in Malawi. The survey also collected information on behaviors associated with HIV acquisition and transmission, and on common HIV comorbidities and other health conditions.
