Avian Influenza Webinars – December 2021

Avian Influenza (Links to the Defra webinars can be found at the bottom of this article)

Avian influenza (AI) is a notifiable disease. All suspect AI cases in poultry and other kept birds must be reported – this is a legal requirement:

As the situation is ever changing, vets, keepers of backyard flocks and any other types of poultry, and wildlife rehabilitators are advised to sign up to the APHA’s Animal Disease alert subscription service to receive immediate notification of new cases and updated zones. Further details can be found here


Clinical signs in birds

The clinical signs of HPAI in birds can include any or a combination of the following3:


Clinical signs can vary according to species of bird, age of bird (for domestic waterfowl) individual immunity and concurrent disease; some species (eg ducks and geese) may show minimal clinical signs.

Spread of AI

Avian influenza is transmitted between birds by direct contact with an infected bird, or indirectly through contaminated body fluids and faeces, as well as by direct or indirect contact with infected wild birds and their secretions/faeces. It can also be spread by contaminated feed and water and other environmental matrices, or by dirty vehicles, clothing, footwear, and equipment. It is not an airborne virus, however there is the risk of droplet transmission.

Control of the disease, both between birds and to humans, is controlled by scrupulous biosecurity, hygiene and appropriate PPE
