From AP News:

“At least three porcupines in Maine have died from a virus that wildlife experts said could pose a threat to the population of the spiky rodents.

Biological samples later diagnosed the porcupines with skunk adenovirus 1, which was first seen in a skunk in Canada in 2014 and has since been spotted in other mammals, including foxes, porcupines and raccoons.

The Maine Department of Inland Fisheries and Wildlife is now working with wildlife researchers, rehabilitators and trappers to study the virus. Dr. David Needle of the University of New Hampshire Diagnostics Lab said it “seems quite likely that this is legitimately a currently emerging disease.”
