A disease that has devastated the bat population across the country has been found in four Illinois counties.  The fungal disease called white-nose syndrome has shown up in bats in Hardin, LaSalle, Monroe and Pope counties, making Illinois the twentieth state to confirm its presence.  

The state's natural resources department says if the disease follows the pattern seen elsewhere, the number of infected animals will balloon in the next few years, prompting major die-offs.  There is no effective cure or treatment.
