September 2024 to January 2025. CAMPHIA 2024-2025 reached adults aged 15 and over in all households in Cameroon. Objective: to measure the impact of the national HIV response and assess progress towards the “95-95-95” targets. The survey estimated prevalence, incidence, and viral load suppression < 1,000 copies/ml at the national and regional levels, 7 years after the first edition of 2017-2018.
Cameroon now has updated data on the HIV epidemic. The results of CAMPHIA 2024-2025, the Evaluation of the Impact of HIV on the Cameroonian Population, have been made public.
Conducted between September 2024 and January 2025, this national household survey targeted adults defined as persons aged 15 and over. It follows CAMPHIA 2017-2018.

Specifically, teams went to households to offer HIV counseling and testing services with immediate results provided to participants. Beyond the test, the survey also collected information on access to and use of care and treatment services for people living with HIV.
Three key indicators were measured, as in 2017: National HIV incidence: the number of new infections; National and regional prevalence: the proportion of people living with HIV; Viral load suppression prevalence VLS: defined as a viral RNA rate < 1,000 copies per milliliter among adults living with HIV.
These figures are essential. They allow us to know if Cameroon is progressing towards controlling the epidemic and achieving the global “95-95-95” targets: 95% of people living with HIV know their status, 95% of those diagnosed are on treatment, and 95% of those on treatment have suppressed viral load.
CAMPHIA 2024-2025 was conducted by the Government of the Republic of Cameroon, under the aegis of the Ministry of Public Health MINSANTE and the National Institute of Statistics INS.
The survey was funded by PEPFAR, the U.S. President’s Emergency Plan for AIDS Relief, with technical assistance from the Centers for Disease Control and Prevention CDC.

On the ground, implementation was ensured by the Cameroon Baptist Convention Health Board CBCHB, INS, and ICAP at Columbia University. Several government entities were mobilized: the Division of Operational Health Research, the National AIDS Control Committee, the National Public Health Laboratory, the Directorate of Disease Control, Epidemics and Pandemics, the Directorate of Pharmacy, Medicine and Laboratories, the Research and Study Center for Emerging and Re-emerging Diseases, and the International Reference Center “Chantal Biya” for HIV/AIDS research. District, regional, and referral hospitals as well as local authorities also participated.
The government, civil society organizations, and international development partners were involved through steering committees and technical working groups throughout the study.
With CAMPHIA 2024-2025, Cameroon therefore has a reliable barometer to adjust its HIV response and accelerate towards eliminating the epidemic as a public health problem.
