The FAO Emergency Prevention System has cautioned about the risk of RVF occurrence in East Africa both in animals and humans, due to favourable environmental conditions and through movement of potentially infected animals, underscoring the urgent need to ensure adequate preparedness for potential outbreak of RVF, through the One Health approach.
During the period of July–October 2023 and over the recent weeks, weter than-normal conditions occurred in the region, and particularly in Sudan, South Sudan and parts of Kenya, Uganda, Ethiopia, Djibouti, Somalia and United Republic of Tanzania. Flooding conditions persisted in the Sudd wetlands in northern South Sudan. These suitable environmental conditions for potential RVF vector amplification, abundance and distribution are forecasted to persist until January 2024 because of a strong El Niño predicted event that is expected to occur with a 75-85 percent chance. Extensive hotspots for RVF vector amplification are predicted in Sudan, South Sudan, Kenya, United Republic of Tanzania, Ethiopia, Uganda, Somalia, and Rwanda.
