The Problem - Mosquito bites cause itching and irritation, and scratching may result in infected sores.
Mosquitoes also transmit serious and sometimes fatal diseases to humans and their pets.
Diseases - Encephalitis is an inflammation of the brain that can be caused by viruses. The symptoms of encephalitis can range from mild to severe. Severe symptoms include rapid onset of severe headaches, high fever, and mental disturbances such as confusion, irritability, tremors, stupor and coma. Not all types of encephalitis viruses are carried by mosquitoes. However, mosquitoes carry at least two types of encephalitis viruses that cause human disease in Illinois.
