How West Nile Virus Spreads: Mosquitoes spread the virus to animals and birds. Culex mosquitoes, originally from Africa, now range from Europe to the Americas

Symptoms and Risks of WNV: Most have no symptoms; about 20% get fever with headaches and nausea. Less than 1% face severe neurological issues
