The first Lesotho Population-based HIV Impact Assessment (LePHIA) was conducted between November 2016 and May 2017 to measure the status of the national HIV response. LePHIA offered HIV counseling and testing with return of results and collected information about household and individual characteristics and the 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.

In November 2019, a second LePHIA survey was launched by the Ministry of Health to assess the country's progress towards HIV epidemic control and reaching the UNAIDS 90-90-90 targets.

The LePHIA 2020 survey is currently in the data collection phase.
