The case fatality rate for hemorrhagic fever is about 50%. Deaths rarely occur in cases of eye disease or meningoencephalitis but 1 to 10% of patients with ocular disease have some permanent visual impairment. The overall case fatality rate for all patients with Rift Valley fever is less than 1%.

Is Rift Valley Fever curable?

There are no FDA-approved treatments for Rift Valley Fever. Because most cases of RVF are mild and self-limiting, a specific treatment for RVF has not been established. Symptoms of mild illness such as fever and body aches can be managed with standard over-the-counter medications.

How long does Rift Valley Fever last?

The symptoms of RVF usually last from 4 to 7 days. While most human cases are relatively mild, a small percentage of patients develop a much more severe form of the disease.

Is Rift Valley Fever fatal?

Is Rift Valley Fever chronic?

Rift Valley fever (RVF) is an acute viral disease that affects domestic animals (such as cattle, buffalo, sheep, goats, and camels). The disease is caused by the RVF virus, generally found in regions of eastern and southern Africa, but also in most countries of sub-Saharan Africa, Madagascar, Saudi Arabia and Yemen.

How do you prevent RVF?

Avoid unsafe animal products. All animal products (including meat, milk, and blood) should be thoroughly cooked before eating or drinking. Protect yourself against mosquitoes and other bloodsucking insects. Use insect repellents and bed nets, and wear long sleeved shirts and long pants to cover exposed skin.

Why is Rift Valley Fever important?

Rift Valley fever (RVF) is a viral zoonosis that primarily affects animals but also has the capacity to infect humans. Infection can cause severe disease in both animals and humans. The disease also results in significant economic losses due to death and abortion among RVF-infected livestock.

How important is Rift Valley Fever to human health?

Is Rift Valley Fever a neglected tropical disease?

Rift Valley fever (RVF) is a zoonotic disease, meaning that it can be transmitted to humans from animals, but the RVF virus can also be transmitted by mosquito bites.In recent decades, formerly neglected tropical infectious agents have been “rediscovered” following their introduction and spread into naïve populations.

How does Rift Valley fever affect the body?

Most commonly, people with RVF have either no symptoms or a mild illness associated with fever and liver abnormalities. Patients who become ill usually experience fever, generalized weakness, back pain, and dizziness at the onset of the illness.

Why Rift Valley fever is emerging?

Rift Valley Fever (RVF) is an emerging zoonosis in Africa and the Middle East. RVF is caused by a negative-strand RNA virus that is naturally transmitted by mosquito, direct contact with infected animals or tissues, and by aerosol.

Which organs of the body are most often targeted by the Rift Valley fever virus in humans?

The most common complication associated with RVF is inflammation of the retina (a structure connecting the nerves of the eye to the brain). As a result, approximately 1% – 10% of affected patients may have permanent vision loss.

What is the diagnosis for Rift Valley fever (VRF)?

Diagnosis. Because the symptoms of Rift Valley fever are varied and non-specific, clinical diagnosis is often difficult, especially early in the course of the disease. Rift Valley fever is difficult to distinguish from other viral haemorrhagic fevers as well as many other diseases that cause fever, including malaria, shigellosis, typhoid fever,…

Can humans get Rift Valley fever from animals?

Key facts Rift Valley fever (RVF) is a viral zoonosis that primarily affects animals but can also infect humans. The majority of human infections result from contact with the blood or organs of infected animals. Human infections have also resulted from the bites of infected mosquitoes.

What is the history of the Rift Valley virus?

The virus was first identified in 1931 during an investigation into an epidemic among sheep on a farm in the Rift Valley of Kenya. Since then, outbreaks have been reported in sub-Saharan Africa. In 1977 an explosive outbreak was reported in Egypt, the RVF virus was introduced to Egypt via infected livestock trade along the Nile irrigation system.

How long does it take to recover from RVF?

Most commonly, people with RVF have either no symptoms or a mild illness that includes fever, weakness, back pain, and dizziness at the onset of illness. Typically, patients recover within two days to one week after symptoms start.
