Resumen
Descripción
Rift Valley fever (RVF) is a vector-borne viral disease endemic to many African countries, posing significant risks to human health, animals, and livestock. Its complex transmission dynamics make monitoring and control challenging. To strengthen early warning and management, FAO developed the Rift Valley Fever Early Warning Decision Support Tool (RVF DST), forecast risks in real time and inform alerts to vulnerable countries. Between August and October 2025, above-average rainfall and widespread flooding—particularly across the Sahel belt from Senegal and Mauritania in the west to Chad, Sudan, Ethiopia, and Eritrea in the east—created favourable conditions for vector proliferation. RVF outbreaks have been confirmed in Senegal, Mauritania, and The Gambia, heightening the risk of further spread across the continent. FAO urges countries to increase awareness, enhance preparedness, and protect vulnerable communities, livestock, and livelihoods. Strengthened coordination between animal health, public health, and environmental sectors is essential to manage ongoing RVF risks effectively.
