West Nile Virus can lead to severe fever, inflammation of the brain and meningitis. It is typically spread by infected mosquitoes, which get the virus from feeding on infected birds. Mosquitoes spread West Nile Virus to humans and other animals when they bite.

About 80% of those infected with the virus do not show symptoms, according to CCCHD.

Those who develop symptoms commonly do so between three to 14 days after they’re bitten.

Up to 20% of people infected will have milder symptoms, including fever, headache, body aches, nausea, vomiting and even swollen lymph glans or a rash on the chest, stomach and back. Symptoms can last for a few days or up to several weeks.

Treatment for West Nile Virus is based off a person’s symptoms.
