People who are most at risk for severe infection include those over 50 years of age and those with chronic illness or compromised immune systems, according to the county.

West Nile virus is transmitted to humans by the bite of an infected mosquito. It is estimated that 20 percent of those who become infected will develop clinically noticeable symptoms of West Nile virus disease.

Mild symptoms may include fever, headache and body aches, skin rash and swollen lymph glands. More severe symptoms include high fever, headache, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss, numbness and paralysis.

West Nile virus can be fatal. Residents who experience symptoms are advised to visit their healthcare providers.  While there is no specific treatment for West Nile virus, patients are treated with supportive therapy as needed.

Among the recommendations: use insect repellent containing DEET, spray clothing with repellent containing permethrin, avoid going outside from dusk to dawn when most mosquitoes are active, wear long sleeves and long pants when nighttime activity is unavoidable, eliminate standing water from flowerpots, clogged gutters, recycle bins, birdbaths, toys, swimming pool and hot tub covers.
