Nigeria

The 2018 Nigeria HIV/AIDS Indicator and Impact Survey (NAIIS) was a cross-sectional survey that assessed the prevalence of key HIV-related health indicators. The survey was a two-stage cluster survey of 88,775 randomly selected households in Nigeria, sampled from among 3,551 nationally representative sample clusters.

The survey included approximately 168,100 participants, ages 15-64 years and children, ages 0-14 years, from the selected household. The 2018 NAIIS characterized HIV incidence, prevalence, viral load suppression, CD4 T-cell distribution, and risk behaviors in a household-based, nationally-representative sample of the population of Nigeria, and described uptake of key HIV prevention, care, and treatment services.

The 2018 NAIIS also estimated the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) infections, and HBV/HIV and HCV/HIV co-infections. The 2018 NAIIS was one of the largest population-based HIV/AIDS household surveys ever conducted.
