What are the symptoms of West Nile virus?
West Nile virus is primarily spread through the bites of infected mosquitoes. People typically develop symptoms two to 14 days after being bitten.
About 80% of people infected with West Nile virus do not develop symptoms, according to the Centers for Disease Control and Prevention. However, there is no way to know in advance who will develop a more serious illness.
Milder symptoms can include:
- Fever
- Headache
- Body aches
- Joint pain
- Vomiting
- Diarrhea
- Rash
Most people with mild illness recover completely, although fatigue and weakness can sometimes last for weeks or months.
Less than 1% of people infected develop serious neurological illness. Symptoms can include high fever, severe headache, neck stiffness, disorientation, tremors, seizures and paralysis. Severe cases can result in death, and some neurological effects may be permanent.
There are currently no specific medicines or vaccines available to treat West Nile virus. People with severe illness may need to be hospitalized for supportive care.

Health officials recommend taking steps to prevent mosquito bites, including:
- Using an EPA-registered insect repellent
