The Lesotho Population-based HIV Impact Assessment (LePHIA) began fieldwork in November 2016 and concluded in May 2017 to measure the status of Lesotho's national HIV response.

LePHIA offered HIV counseling and testing with return of results, collected information about household and individual characteristics and uptake of HIV care and treatment services.

The survey team visited over 10,000 households, interviewed participants and provided HIV counseling and testing.

The preliminary results were announced in November 2017 and the final report was released in September 2019.
