WEST NILE UPDATE:
SPRINGFIELD, IL The Illinois Department of Public Health today reported that a dead crow found in Crawford County has tested positive for West Nile virus. This is the first county outside of northern Illinois where the virus has been detected.
The crow collected in Palestine in Crawford County on Sept. 26 was identified as preliminarily positive by the Illinois Department of Agriculture lab in Galesburg. Previously, birds have been found with West Nile virus in Cook, DuPage, Lake, Will and Winnebago counties.
