Influenza Viruses - H?N?


H = Hemagglutinin16 versions

N = Neuram9 versi

Hs and Ns Tell us the strain of the virus

Can tell us some about thehuman health risk

High and Low Pathogen Tell us the severity of disease

domesticated poultry

Know the warning signs of Infectious Bird Diseases Early detection is important to prevent the spread of disease

Sudden increase in bird deaths in your flock

Sneezing, gasping for air, coughing, and nasal discharge

Lack of energy and poor appetite Watery and green diarrhea

Drop in egg production or soft- or thin-shelled misshapen eggs

Biosecurity: Step 5 Know the Warning Signs


19/24

There have been no known human cases of influenza caused by H5N2 orH5N8 strains to date.

HOWEVER

Those with contact with poultry should have annual influenza vaccine

If a producer has influenza-like illness, they should limit contact with theirchickens to reduce the risk of co-infection with seasonal flu and avianinfluenza.

Human Health Concerns


20/24

WSDA, USDA and WSU Laboratories are working together to increase

surveillance (testing) of poultry This will help us detect any issues sooner

What Will Happen if My Flock is Found Positive forHighly-Pathogenic Avian Influenza?

Laboratory confirmation of HPAI.

Humane depopulation with compensation.

Appropriate disposal, which may include onsite (In Place) composting.

Cleaning and disinfection of premises. Repopulation allowed after an appropriate down time.

These measures may seem drastic and would be unfortunate for a producerto face, but are necessary to control the spread of this highly-contagiousdisease to other flocks.

What if?
