Objective

The goal of the survey is to examine the distribution of human immunodeficiency virus (HIV) disease in Nigeria, to assess the coverage and impact of HIV services on the population level, and to measure HIV-related risk behaviors using a nationally-representative sample of persons aged 0-64 years.

Government and the people of Nigeria

Primary Objectives

To estimate the following in a household-based, nationally-representative sample of adults, age 15-64 years:

• 1) National HIV incidence (i.e., prevalence of recent HIV infection).
• 2) National and sub-national (State) prevalence of suppressed HIV viral load (VL) (Less 1000 copies/mL).
• 3) National and sub-national (State) HIV prevalence

Secondary Objectives

To estimate the following among adults 15-64 years:

• 1) Prevalence of HIV-related risk behaviors, knowledge, and attitudes
• 2) Behavioral and demographic determinants of HIV incidence and prevalence
• 3) National prevalence of HBV infection
• 4) National prevalence of HCV infection
• 5) Prevalence of HIV/ HBV co-infection among HIV+ individual
• 6) Prevalence of HIV/ HCV co-infection among HIV+ individual

To estimate the following among adults ages 15-64 and children ages 0-14 years

• 7) Uptake of HIV-related services (especially prevention of mother-to-child transmission (PMTCT)-related services) and exposure to HIV interventions
• 8) Distribution of CD4 T-cell counts among HIV+
• 9) Prevalence of transmitted drug resistance (DR)
To estimate the following among adults 18 – 54 years: 10) Population size of men who have sex with men (MSM), female sex workers (FSW), people who inject drugs (PWID) using the network scale-up method (NSUM)

To estimate the following among children 0-14 years:

• 11) National pediatric HIV prevalence
• 1.2 Country context
