West Nile fever is a viral infection typically spread by mosquitoes. In about 75 per cent of infections people have few or no symptoms. About 20 per cent of people develop a fever, headache, vomiting, or a rash. In less than one per cent of people, encephalitis or meningitis occurs, with associated neck stiffness, confusion, or seizures.
