Bats White-Nose Syndrome FAQs - 6 Found
White-nose syndrome (WNS) is an emergent disease of hibernating bats that has spread from the northeastern to the central United States at an alarming rate. Since the winter of 2007-2008, millions of insect-eating bats in 29 states and five Canadian provinces have died from this devastating disease. (see map below) The disease is named for the white fungus, Pseudogymnoascus destructans, that infects skin of the muzzle, ears, and wings of hibernating bats. In 2016, WNS was confirmed in Washington and Rhode Island.
White-nose Syndrome (WNS) is a disease that is killing hibernating bats in eastern North America. WNS was first documented at four sites in eastern New York 2007. After that, photographs taken in February 2006 were found, showing affected bats at another site.
Named for the white fungus on the muzzles and wings of affected bats, WNS has rapidly spread to many sites throughout the eastern United States and into Canada. The fungus that causes WNS has been detected as far west as Oklahoma. Researchers associate WNS with the newly identified fungus, Pseudogymnoascus destructans, which thrives in cold and humid conditions characteristic of caves and mines used by bats.
Bats affected with WNS do not always have obvious fungal growth, but they may behave strangely within and outside of their hibernacula (caves and mines where bats hibernate during the winter).
