An outbreak of Rift Valley fever (RVF) is ongoing in Senegal, which was declared by health authorities after confirmation of the first case on November 10 by the Pasteur Institute of Dakar.
As of November 18, a total of 3 cases and zero deaths are reported in the health districts of Gossas and Diofior, in the Fatick region.
Rift Valley Fever is an acute viral hemorrhagic fever that causes illness in animals (such as cattle, buffalo, sheep, goats, and camels).
Most people with RVF have either no symptoms or a mild illness with fever, weakness, back pain, and dizziness. A small percentage (8-10%) of people with RVF develop much more severe symptoms, including eye disease, hemorrhage (excessive bleeding), and encephalitis (swelling of the brain). Most people recover within one week. Approximately 1% of people who get RVF die.
