Highly pathogenic avian influenza (HPAI) is a disease carried by wild birds that can affect domestic birds. Avian influenza is caused by the influenza Type A virus (influenza A). The virus is shed in the feces and respiratory secretions of infected birds and is able to survive for weeks in cool, damp environments.
Despite the recent snow and cold, millions of birds are set to begin migrating this spring. Positive cases of HPAI in backyard and commercial flocks are currently occurring across the U.S. Now is the time for poultry and bird owners to ramp up biosecurity efforts.
“One of the first clinical signs of HPAI is sudden, unexplained death,” says Dr. Gerald Stokka, North Dakota State University Extension veterinarian and livestock stewardship specialist. “Most HPAI cases are reporting a decline in water and feed consumption prior to the unexplained death.”
Decreased egg production and depression in layers may be another sign that birds are not feeling well. Purple or dry combs, being quieter than normal, frequent laying down and swelling around eyes are other symptoms birds may experience.
“The best way to reduce the potential for transmission of HPAI is to reduce interaction between wildlife and domestic flocks,” says Dr. Stokka. “Wild birds and mammals, such as foxes, coyotes and raccoons, are transmission vectors to your domestic flocks.”
NDSU Extension specialists have developed tips for reducing transmission of HPAI.
