West Nile virus is a mosquito-borne virus that is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected bird. Most people who are infected with the West Nile virus have no symptoms or experience very mild symptoms three to 14 days after the bite of an infected mosquito. Mild symptoms include a fever, headache and body aches, occasionally with a skin rash on the trunk of the body and swollen lymph glands.
Less than 1 percent of infected people with West Nile virus will develop severe symptoms. These symptoms include headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness and paralysis. Persons older than 50 years of age and persons with weak immune systems have the highest risk of severe disease, city officials said.
The best way to prevent West Nile disease or any other mosquito-borne illness is to reduce the number of mosquitoes around the home and to take personal precautions to avoid mosquito bites.
