The Haiti Population-Based HIV Impact Assessment (HAPHIA) was a household-based national survey among adults (defined as individuals aged 15-64 years) conducted between July 2019 and November 2020 to measure the impact of the national HIV response. HAPHIA offered HIV counseling and testing with return of results and collected information about uptake of HIV care and treatment services. HAPHIA was the first survey in Haiti to estimate national HIV incidence, and national and subnational prevalence of HIV and viral load suppression (VLS), defined as HIV RNA <1,000 copies per milliliter (mL).
The duration of the fieldwork was longer than expected and took place over three periods: July 2019 to September 2019, January 2020 to March 2020, and October 2020 to November 2020. The first pause was due to security unrest; the second pause was due to the state of emergency period for the COVID-19 pandemic. The results provided information on national and subnational progress toward control of the HIV epidemic. Please use these summary results in line with the content of the full final report of HAPHIA.
