Avian metapneumovirus (aMPV) is a viral upper respiratory disease of poultry including turkeys, broilers, layers, and breeders. It may also affect other poultry and avian species such as pheasants, Muscovy ducks, pigeons, and various wild birds. The 2024 outbreak consists of two distinct groups. Eastern states have been affected by avian metapneumovirus subtype B. Western states have been affected by avian metapneumovirus subtype A. All detections from previous aMPV outbreaks in the US were subtype C. Dr. Lindy Chiaia, vice president of scientific and regulatory affairs with the National Turkey Federation, joins us with an update on the disease and efforts underway to address it.
