A fungal outbreak in the eastern and Midwestern United States is infecting some populations of wild snakes. Snake Fungal Disease (SFD), a fungal dermatitis consistently associated with the fungus Ophidiomyces ophiodiicola, is showing recent spikes in occurrence according to the U.S. Geological Survey’s National Wildlife Health Center (NWHC) and other diagnostic laboratories. So far, the diseased snakes submitted by Wildlife Monitors to the NWHC are attributed to wild populations from nine states, including Florida, Massachusetts, New York, New Jersey, Tennessee, Illinois, Minnesota, Ohio, and Wisconsin.
