Dr. Lumpkin reminded Illinoisans it was still important to take the following steps to reduce the chance of mosquito bites until their area experiences a hard frost:
The Culex or house mosquito, which can carry West Nile virus or St. Louis encephalitis virus, breeds in warm, stagnant water and remains active and biting until there is a hard frost. As the temperatures dip below 60 degrees at night and in early morning, the mosquitoes' feeding habits change from seeking blood meals, which they use for reproduction, to sugar meals from plants that help sustain them over winter.
Dr. Lumpkin said most people who get infected with West Nile virus have either no symptoms or mild symptoms, but a few individuals may develop a more severe form of the disease, such as encephalitis or meningitis.
Most people infected with West Nile virus have no clinical symptoms of illness, but some may become ill three to 14 days after the bite of an infected mosquito. Infections can be mild and include fever, headache and body aches, or severe and marked by headache, high fever, neck stiffness, stupor, convulsions, muscle weakness, paralysis and, rarely, death. Serious West Nile virus illness is most often present in individuals 50 years of age or older.
A total of 513 birds, 528 mosquito batches and 431 horses in 98 Illinois counties have tested positive this year for the virus since surveillance for the mosquito-transmitted virus began on May 1.
