Tainted Wolves

Each year, nearly 70 percent of gray wolf pups in Minnesota die from a virus common in domestic dogs. Scientists believe that a series of rare mutations and increased air travel helped a feline virus jump from cats to dogs, and then to gray wolves. TAINTED WOLVES explores the threat to gray wolf populations from canine parvovirus, the factors helping its spread, and the lessons we can draw from viruses – HIV1, SARS Coronavirus, HINI swine flu – that jump from one species to another.
