Jumping Species
Canine flu was first discovered last year after an unusual illness began to appear at greyhound racetracks in Florida.
Cornell virologists, working with researchers at the CDC and the University of Florida, determined the sick greyhounds had a type of influenza ordinarily found only in horses.
This finding is the first scientific report of an equine influenza virus jumping the species barrier, and researchers are unsure how it occurred.
Virtually 100 percent of exposed dogs become infected, the researchers said. The virus is spread from dog to dog via coughing, contaminated objects, and even people.
Nearly 80 percent of dogs exposed to the virus contract only a mild form of the disease, which mimics kennel cough—a type of canine bronchitis that is rarely serious.
Canine influenza symptoms include low-grade fever, cough, and nasal discharge.
Nearly 20 percent of infected animals do not display any clinical signs but can still spread the disease.
