Background
Avian influenza (AI) is an infectious viral disease of birds (especially wild waterfowl such as ducks and geese), often causing no apparent signs of illness. AI viruses can sometimes spread to domestic poultry and cause large-scale outbreaks of serious disease.
AI viruses are divided into two groups based on their ability to cause disease in poultry:
- High pathogenicity (HPAI)
- Highly pathogenic viruses result in high death rates (up to 100% mortality within 48 hours) in some poultry species.
- Low pathogenicity (LPAI)
- Low pathogenicity viruses also cause outbreaks in poultry, but are not generally associated with severe disease.
Prevention
Following strict biosecurity practices is key to preventing HPAI infection. Biosecurity is a set of practices designed to reduce the risk of spreading disease from sick birds and birds carrying the virus, to healthy ones.
We recommend adding these practices to your routine:
- Restrict access to your property and keep your birds away from other birds.
- Keep a designated pair of shoes to wear around your birds, wash clothing after visiting your birds, and use disinfectants correctly.
- Clean and disinfect cages, poultry equipment, and car tires after visiting a farm store, poultry swap, or other location with birds present.
- Keep new birds separate from your flock for 30 days; quarantine returning birds from the rest of your flock after visiting a poultry swap or other event.
- Do not share equipment or supplies with others, but if you must, disinfect it first.
- Wash hands before and after bird handling.
Outbreak information and updates
The following Regional Quarantines are currently in effect to prevent the spread of Highly Pathogenic Avian Influenza:
A map of all active outbreak areas in Oregon as well as any active quarantine areas is available online. Interested parties may enter their address to determine whether they are included in a quarantine area.
After confirmed cases of HPAI in poultry flocks, regional quarantines for all avian species and vehicle traffic involved with avian species may be implemented for areas extending a minimum of 10 kilometers around the infected properties.
