A mysterious ailment that is decimating bat colonies in the Northeast has spread more quickly than scientists once believed. "White-nose syndrome," first discovered in 2007, has been confirmed for the first time in New Hampshire and West Virginia. And scientists are investigating suspected sites in Virginia.
Susi von Oettingen, a biologist with the U.S. Fish and Wildlife Service, says the disease was confirmed last month in West Virginia, home to some of country's rarest and most diverse bat populations.
