What should cavers know and do in regard to White-nose Syndrome?
In response to White-nose Syndrome (WNS), the U.S. Fish and Wildlife Service and individual states request that cavers observe all cave closures and advisories, and avoid caves, mines or passages containing hibernating bats to minimize disturbance to them. The Service asks that cavers and cave visitors stay out of all caves in the affected states and adjoining states to help slow the potential spread of WNS. Local and national cave groups have also posted information and cave advisories on their websites.
Learn more at the website for the White-Nose Syndrome Response Team, a partnership of North American agencies and organizations that includes the USGS.

Does White-nose Syndrome pose a risk to human health? Does White-nose Syndrome pose a risk to human health?
Thousands of people have visited affected caves and mines since White-nose Syndrome (WNS) was first observed, and there have been no reported human illnesses attributable to WNS. We are still learning about WNS, but we know of no risk to humans from contact with WNS-affected bats. However, we urge taking precautions and not exposing yourself to WNS. Biologists and researchers use protective...
What is White-nose Syndrome? What is White-nose Syndrome?
White-nose syndrome 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 at least 40 states and eight Canadian provinces have died from this devastating disease. The disease is named for the white fungus, Pseudogymnoascus destructans, that infects skin of...

If you find a dead or dying bat: Contact your state wildlife agency, file an electronic report in those states that offer this service, e-mail U.S. Fish and Wildlife Service biologists in your area or contact your nearest Fish and Wildlife Service field office to report your potential White-nose Syndrome (WNS) observations. It is important to determine the species of bat in case it is a federally...
What species of bats are affected by White-nose Syndrome? What species of bats are affected by White-nose Syndrome?
White-nose Syndrome mostly affects hibernating bats. More than half of the 47 bat species living in the United States and Canada hibernate to survive the winter. Twelve bat species, including two endangered species and one threatened species, have been confirmed with white-nose syndrome in North America. The causative fungus, Pseudogymnoascus destructans ( Pd), has been found on an additional six...
How are bats affected by wind turbines? How are bats affected by wind turbines?
Dead bats are found beneath wind turbines all over the world. It’s estimated that tens to hundreds of thousands die at wind turbines each year in North America alone. Unfortunately, it’s not yet clear why this is happening. It’s possible that wind turbines interfere with seasonal migration and mating patterns in some species of bats. More than three-quarters of the bat fatalities at wind turbines...

Bat White-nose Syndrome: There is a New Fungus Among Us By Dr. David Blehert
Since first discovered in 2007 in New York, white-nose syndrome has spread to 16 states, including Virginia and Maryland, and four Canadian provinces. The disease is estimated to have killed over five million hibernating bats.
