MOSQUITO SURVEILLANCE AND CONTROL GRANTS
SPRINGFIELD, IL -- Twenty local health departments have been awarded $213,214 for surveillance and control of Asian tiger mosquitoes and other container-breeding mosquitoes, Dr. John R. Lumpkin, state public health director, announced today.
The grants will assist local health departments in developing and administering vector control programs that evaluate the threat to the public's health from viruses carried by mosquitoes.
Surveillance and control efforts will include identification of sites where tires have been stored or discarded; cleanup of noncommercial tire sites; if necessary, legal action to force cleanup; and sampling mosquitoes found in tires for the presence of viruses.
The grant money awarded by the Department comes from its share of the state's Used Tire Management Fund. Money for the fund is generated by a $1 per new tire fee.
Grants are awarded on the basis of several factors, including the presence of the Asian tiger mosquito, large or numerous used tire sites, past cases of mosquito-borne encephalitis, geographic region and population size.

The Asian tiger mosquito has been identified in 14 Illinois counties -- Alexander, Cook, Jackson, Jasper, Jefferson, Kankakee, Macoupin, Madison, Massac, Pulaski, Randolph, St. Clair, Union and Williamson. It is a persistent and aggressive daytime-biting mosquito that breeds in containers that hold water, such as tires, cans and yard ornaments.
The Asian tiger mosquito, which arrived in the United States in 1985, apparently in used tires shipped from Japan, has been found to carry viruses that can be transmitted to humans. However, there are no documented cases of the Asian tiger mosquito spreading disease to a human in the continental United States.
Other container-breeding mosquitoes, such as the tree-hole mosquito and the northern house mosquito, are known to transmit diseases to humans. California (LaCrosse) encephalitis is spread by the tree-hole mosquito and St. Louis encephalitis is transmitted by the northern house mosquito.
California and St. Louis encephalitis are serious diseases that affect the brain. California encephalitis occurs more often in children, while St. Louis encephalitis is more common among adults. Most victims recover fully, although some may have permanent neurological damage.
There were four confirmed cases of California encephalitis reported in Illinois last year, but no cases of St. Louis encephalitis.
Symptoms of both diseases are similar and usually begin five to 15 days following a bite by an infected mosquito. The symptoms range from a slight fever or headache to rapid onset of severe headache, high fever, muscle aches, stiffness in the back of the neck and disorientation.
The tree-hole mosquito is infected with California encephalitis virus by feeding on infected small mammals or when an infected female mosquito transmits the virus to her offspring. The house mosquito is infected with St. Louis encephalitis by feeding on birds that carry the virus.
