Rift Valley fever (RVF) is an illness that is primarily spread by direct contact with blood, fluids, or tissues of infected animals such as cattle, buffalo, sheep, goats, and camels. Less commonly, it can also be spread through mosquito bites.

Most people with RVF do not feel sick or have only mild illness. Symptoms of RVF include fever, weakness, back pain, dizziness, and weight loss. However, a small percentage (8%–10%) of people may have more serious illness, such as severe bleeding, swelling of the brain, or eye disease. Approximately 1% of people who get RVF die from the disease.
