PULLMAN, Wash. (AP) - Researchers say a serious new form of a viral poultry disease has been found in Washington state.
Infectious bursal disease virus, known as IBDV for short, is not known to infect people or other animals. Washington State University's animal disease lab says it has been confirmed in one flock of birds here - the first confirmed case in the United States outside of California.
The disease can kill many birds in a flock and hits young birds especially. It can also suppress their immune system, making them more susceptible to secondary diseases.
