Frequently Asked Questions About West Nile Virus
What are the symptoms of infection?
Most individuals infected with West Nile virus will not have any symptoms or signs of illness. People who do develop illness may experience symptoms that seem like a mild flu. These symptoms may include a low fever, headache, body aches, skin rash and swollen lymph glands. Symptoms generally appear 3 - 14 days following the bite of an infected mosquito.
Who is most vulnerable to more serious effects?
People 50 years of age and older have the highest risk of developing more severe disease with symptoms such as high fever, neck stiffness, disorientation, convulsions, paralysis and, rarely, death.
What can I do to reduce my risk?
Avoid areas with mosquitoes. When outdoors, wear long pants and long-sleeved clothing and spray arms and legs with an insect repellent. See repellent recommendations. Eliminate any standing water around your home where mosquitoes may breed. Repair any damaged window screens.
