What is West Nile virus?

West Nile virus is a disease that is spread by the bite of an infected mosquito. Mosquitoes become infected when they feed on the blood from infected birds.

The infected mosquitoes can then transmit West Nile virus to humans and animals. West Nile disease can vary in severity. People 50 years of age and older have the highest risk of severe disease.

Severe West Nile virus infections can cause neurologic complications such as encephalitis. Milder symptoms include fever, headache and muscle aches.
