New Jersey Avian Influenza Response Plan Birds Presented
New Jersey Avian Influenza Response Plan (Birds) Presented by: NJ Department of Agriculture 1
Avian Influenza Virus: Review • • • Orthomyxovirus, type A Serologically categorized (H 1 -H 15) and (N 1 -N 9) H 5 and H 7 subtypes: reportable US $23. 3 billion poultry industry NJ $35 million/year poultry industry Economic loss – direct/indirect 2
Avian Influenza and Poultry • Highly Pathogenic • Apocalyptic: 100% mortality within 24 hours of exposure (no time for clinical signs to develop) Erica Spackman Southeast Poultry Research Laboratory USDA-ARS, Athens, GA 3
Transmission • Direct contact from infected birds – Virus is excreted from the respiratory tract, conjunctiva, and in feces – Virus can survive long term in cool moist environments – Migratory waterfowl may be the source of infection 4
Transmission • Fomites – Movement of materials exposed to infected birds and carcasses, – Obvious: Contaminated feed, water, implements – Potentially overlooked: People, pets, vehicles 5
Current Situation: Asian HPAI • Current outbreaks remain primarily an animal disease • Early detection and rapid response to an outbreak are crucial to control the disease and minimize the number of animals affected • Eradicating at the farm may prevent a human pandemic 6
Asian H 5 N 1 HPAI Epizootic The Beginning, 1996 • • • Guangdong, China Geese with some mortality H 5 N 1 AI virus – HP for chickens • 1997, Hong Kong: • 18 human cases, 6 deaths • Depop. 1. 4 m poultry David E.

Assumptions 1. Asian HPAI H 5 N 1 will continue to spread globally a. 55 countries as of 8/06 vs. 45 countries as of 4/06 2. Entry into North America: a. Migratory birds b. Imported birds and products c. Smuggled birds and products 3. Once introduced into wild bird population response will continue until… 12
Influenza in Migratory Birds • Estimated that 5 million birds (over 300 species), migrate from North America to Central and South America, and similar numbers travel from Eastern Europe to Africa each fall. • Gill FB. Ornithology. 2 nd ed. New York: Freeman; 1994. 13
Imported birds/products Risks: Preventive measures: • Potential delay between initial identification of disease and embargo • Illegal importation • • Embargoes placed on countries/regions with documented infection Reporting requirements – OIE 14
Protecting New Jersey’s Birds … … key to preventing spread of HPAI virus 15
Preventing spread of HPAI virus • Early detection Strong surveillance program • Limit spread of virus Effective quarantine zones • Elimination of virus Cleaning & disinfection 16
Eliminate virus at point of origin • Enhanced surveillance of avian populations – Commercial poultry – Live bird marketing system – Non-commercial poultry/domestic fowl • Non-domestic bird populations - Wild bird populations - Zoo/exhibit birds - Wildlife rehabilitators 17
