Although temperatures have been near freezing in many parts of the state
recently, Dr. John R. Lumpkin, state public health director, reminded
Illinoisans it is still important to take steps to reduce the chance of
mosquito bites until their area experiences a hard frost (27 degrees F or
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.
EDITOR'S NOTE: West Nile disease case updates will be issued on Tuesdays and Thursdays unless there is a fatality or a human case is reported in a county for the first time.
