IDPH officials say Macon County mosquito batch tests positive for West Nile virus

SPRINGFIELD - Illinois Department of Public Health officials have announced that a mosquito batch in Macon County has tested positive for West Nile virus.

Officials say the positive mosquito batch was collected on May 28, 2015 in Decatur by Macon County Mosquito Abatement District employees.  The positive result is the first one in central Illinois, and follows a positive result in St. Clair County last week.

West Nile virus is transmitted through the bite of a mosquito that has picked up the virus from feeding on an infected bird.  Common symptoms of West Nile virus include fever, nausea, headache, and muscle aches.  However, in rare cases, the virus can cause severe illness and even death.  IDPH officials say individuals over the age of 50 and people with compromised immune systems are more likely to experience severe illness associated with West Nile virus.

Officials suggest taking steps to reduce your exposure to mosquitoes in order to lower your risk of contracting West Nile virus.  For more information on West Nile virus, visit
