The Tanzania HIV Impact Survey 2022-2023 (THIS 2022-2023) was a household-based national survey among adults (defined as those aged 15 years and older) that measured the impact of the country’s national and regional HIV response.
THIS 2022-2023, which was conducted from November 2022 through March 2023, offered HIV counseling and testing with return of results, and collected information about uptake of HIV prevention, care and treatment services. THIS 2022- 2023 estimated national HIV incidence and national and regional HIV prevalence among adults, as well as national and regional prevalence of viral load suppression (VLS), defined as HIV RNA <1,000 copies per mL among adults living with HIV. THIS 2022-2023 also provided critical information on national and regional progress toward HIV epidemic control—including progress towards achieving the Joint United Nations Programme on HIV/AIDS (UNAIDS) 95-95-95 targets.
