Illinois' first case this year of West Nile virus in a bird has been confirmed. According to the Illinois Department of Public Health (IDPH) the infected starling was collected by the Monroe County Health Department on June 27 in Waterloo, Ill.
This pattern of detection is part of an annual trend seen by health officials in which the West Nile virus is first detected in mosquitoes, followed by birds, and then, people. No cases have been reported so far this year in humans. However, according to health officials, it is only a matter of time before a person is infected.
