The agency reported 67 confirmed cases in each of the following nations: Burkina Faso, Cameroon, the Central African Republic, Côte d’Ivoire, Ghana, Guinea, Liberia, Togo, and Nigeria. WHO officials cited cross‑border population movements, the spread of the disease‑carrying mosquito, and uneven vaccination coverage as key factors increasing the risk of transmission and expanding the outbreak’s reach. The organization classified the current health risk as medium at the regional level and low on a global scale.
