Rift valley fever
Rift valley fever (RVF) is an acute, fever causing viral disease that affects domestic animals (like cattle, sheep and goats) and humans. RVF is associated with mosquito-borne epidemics during years of unusually high rainfall.
How it is spread Humans can get the disease if they are exposed to the blood, body fluids or tissue of infected animals. Direct exposure can occur during slaughter or veterinary and obstetric procedures. Humans can also get RVF through bites from infected mosquitoes.
Signs & Symptoms
People with RVF typically have either no symptoms or a mild illness associated with fever and liver abnormalities. In some patients the disease can progress to haemorrhagic fever, inflammation of the brain or diseases affecting the eyes. Patients who become ill usually experience fever, generalised weakness, back pain, dizziness and extreme weight loss.
People who regularly work with animals, must avoid coming in contact with the blood or tissue from sick animals. Reduce your contact with mosquitoes by wearing long-sleeved clothing and using mosquito repellents and bed nets.
There is no established course of treatment for patients infected with the RVF virus.
