Nigeria has launched its first nationally representative survey on antimicrobial resistance to generate critical data to guide evidence-based policies, improve patient outcomes, and strengthen health system resilience.
Antimicrobial resistance occurs when bacteria, viruses, fungi, and parasites evolve to resist treatment, making infections harder to cure.
As a result, surveillance is essential to track resistance patterns, identify priority pathogens, and guide targeted interventions and with support from the World Health Organization (WHO) and other partners, the initiative marks a milestone in the country’s public health response.
Nigeria becomes the third country globally to partner with WHO on a national antimicrobial resistance survey. having been selected based on the country’s strong commitment to AMR surveillance, its updated WHO Nigeria NAP 2.0, and readiness to expand laboratory and data systems.
Africa’s most populous country ranks 20th globally for age-standardized mortality due to antimicrobial resistance . In 2019, an estimated 263,400 deaths in Nigeria were linked to it—more than the combined deaths from enteric infections, tuberculosis, respiratory infections, maternal and neonatal disorders, neglected tropical diseases, malaria, and cardiovascular diseases.
Globally, resistant infections in tertiary care settings cost between $2,371 and $29,289 per patient episode, extend hospital stays by an average of 7.4 days, and increase mortality risk by 84 per cent.
The survey will see the establishment of a national baseline on antimicrobial resistance prevalence to monitor interventions, assess the distribution, burden (morbidity, mortality, DALYs, cost), and diversity of AMR across regions and populations, as well as contribute to the global target of reducing AMR deaths by 10 per cent by 2030, in line with the political declaration endorsed at the 79th United Nations General Assembly in 2024.
It also seeks to strengthen routine antimicrobial resistance surveillance, including diagnostics, sample referral systems, and laboratory capacity.
Using WHO’s standardized methodology, the survey will run for 12–15 months and cover 40–45 randomly selected health facilities nationwide. Patients with suspected bloodstream infections (BSIs) will be identified using standard case definitions, and blood samples will be analysed in quality-assured laboratories.
Data will be collected across all age groups, covering clinical, demographic, laboratory, financial, and outcome indicators. Follow-up will occur at discharge, 28 days, and three months post-infection. The survey will sample approximately 35,000 patients suspected of BSIs to obtain around 800 isolates of the most common pathogens.
Dr Tochi Okwor, Acting Head, Disease Prevention and Health Promotion, Nigeria Centre for Disease Control and Prevention (NCDC) said, “With WHO’s support, we are confident the survey will generate the evidence needed to protect public health.”
WHO Representative in Nigeria, Dr Pavel Ursu, reaffirmed WHO’s commitment stating that ,“Nigeria is taking a decisive step toward combating AMR with an approach grounded in data, science, and measurable impact. This survey will provide the clarity needed to drive smarter policies, stronger surveillance, and better patient outcomes. Nigeria is laying the foundations for a resilient health system, one that protects lives, strengthens trust, and ensures that essential medicines remain effective for future generations.”
Adding her input, Dr Laetitia Gahimbare, Technical Officer at WHO Regional Office for Africa, added:“Strengthening surveillance enhances Nigeria’s capacity to detect and respond to AMR threats, supporting better patient outcomes, reinforcing health security, and building a resilient system.”
Professor Babatunde Ogunbosi, Paediatric Infectious Diseases Specialist at University College Hospital, Ibadan, highlighted the broader impact:, “This survey is about more than data. It’s about building national capacity for research, diagnostics, and policy. It integrates science into public health decision-making.”
