The symptoms

In most cases, there are no symptoms. When symptoms do occur, they are similar to a mild flu-like illness with fever, headache and muscle aches.

About one in 150 people develop more severe illness with encephalitis or meningitis.

Who's at risk?

People most at risk of developing more severe illness are those over 50 and those who already have another illness.

West Nile virus is commonly found in Africa, West Asia, and the Middle East. Since 1999, it has also spread into North America.

In temperate climates, for example Russia and northern North America, cases normally occur in the late summer and early autumn. In tropical climates, the virus can be transmitted all year round.


When travelling to parts of the world where transmission of the virus to humans occurs, it's important to protect against mosquito bites by taking anti-mosquito measures. For example, by using mosquito repellent, wearing long sleeves and trousers and sleeping under mosquito nets.


There's no specific treatment for West Nile virus. When someone is severely ill, then supportive treatment, which may include intravenous fluids, is given.
