West Africa is once again at the center of an avian influenza storm. Outbreaks of H5N1 have swept through Nigeria, Senegal, and Côte d’Ivoire, threatening food security, livelihoods, and regional stability. These developments come as the virus makes alarming advances globally, with Australia reporting its first case and mass die-offs of elephant seals in the Southern Ocean. Together, these events underscore that Africa’s crisis is part of a much larger global wave.
In Nigeria, multiple outbreaks were confirmed in Kebbi, Kano, Katsina, Plateau, and Bauchi states. As West Africa’s largest poultry producer, Nigeria’s crisis has regional ripple effects, disrupting supply chains and raising fears of protein shortages. Senegal, meanwhile, reported its first outbreak in three years, traced to ducks purchased in Fatick and later spreading to a farm in Dakar. Ivory Coast faced its own devastating blow in April, when nearly 95,000 birds were lost in Koun-Fao, ending a five-year lull without cases. Reports from Ecofin Agency and FeedBusinessMEA confirm that West Africa is reliving the devastating 2021 wave, when nine countries were affected.
Globally, the situation is equally alarming. On June 19, 2026, Australia reported its first detection of H5N1 in a migratory bird, marking the virus’s arrival. Just a day earlier, mass mortality among elephant seals was recorded on Heard Island, highlighting the virus’s ecological reach and adaptability to new hosts. South Africa has also made headlines by approving a controlled vaccination framework for highly pathogenic avian influenza, a landmark policy shift that could set precedent for other African nations.
The implications for Africa are profound. Poultry remains a cornerstone protein source, and outbreaks threaten both nutrition and affordability. Smallholder farmers, who dominate the sector, face devastating losses that ripple through rural economies. Wildlife vulnerability is another concern, as global spillover into seals and polar bears raises alarms for Africa’s coastal and migratory bird populations. At the policy level, South Africa’s vaccination framework may inspire West African governments to adopt immunization strategies instead of relying solely on culling, which has proven costly and disruptive.
Veterinary experts are urging immediate action. Enhanced surveillance of migratory birds and poultry farms is critical, alongside stricter biosecurity measures at markets and smallholder operations. Regional cooperation will be essential to manage cross-border risks, while vaccination strategies must be carefully evaluated in light of South Africa’s controlled rollout. The challenge is urgent: protect poultry industries, safeguard food security, and prepare for a virus that is proving more adaptable than ever. Africa’s avian influenza crisis is part of a global wave reshaping how the world responds to H5N1.
