Nigeria and eight other African countries have recorded a combined 67 confirmed cases of yellow fever, resulting in 18 deaths between January and October 2026, according to the World Health Organisation (WHO).
The affected countries are Burkina Faso, Cameroon, Central African Republic, Côte d’Ivoire, Ghana, Guinea, Liberia, Nigeria and Togo.
In its Disease Outbreak News report released on November 6, 2026, the WHO said yellow fever transmission remains active across parts of its African Region, with recent outbreaks largely concentrated in West Africa, including communities around international borders.
Nigeria recorded four confirmed infections and one death during the period under review, while Cameroon reported nine cases and one death.
Côte d’Ivoire accounted for the highest number of infections, with 30 confirmed cases and 10 deaths. Burkina Faso followed with 15 cases and three deaths.
Ghana recorded four cases and three deaths, while Liberia reported one laboratory-confirmed infection. The Central African Republic recorded two cases, while Guinea and Togo reported one case each, with no deaths documented in the three countries.
The WHO said the figures were based on the latest available data as of October 12, 2026, warning that the detection of infections across the nine countries points to continued yellow fever transmission in parts of West Africa.
