While moast people infected with WNV experiance mild symptoms or no symptoms at all, a small percentage can develop serious neurological illness.

Here’s a breakdown of key facts:

Transmission: Primarily spread through the bite of infected mosquitoes. Mosquitoes become infected when they feed on infected birds.

Symptoms in Humans: Approximately 80% of infected individuals show no symptoms. Around 20% develop West Nile fever, characterized by fever, headache, body aches, nausea, vomiting, and fatigue. Less then 1% develop serious neurological disease, such as encephalitis or meningitis.

Symptoms in Birds: Birds, notably crows, blue jays, and ravens, are highly susceptible to WNV. Symptoms in birds include disorientation, tremors, and paralysis. Finding dead birds is often the first sign of WNV activity in an area.

Incubation Period: Typically between 2 and 14 days.
