International assistance l.jpg
International Assistance Influenza

  • USDA is providing assistance to international organizations by providing:

    • Technical expertise and assessments for countries affected by AI

    • Financial assistance


Usda s longstanding domestic interventions l.jpg
USDA’s Longstanding Domestic Interventions Influenza

  • Targeted surveillance/cooperative efforts with States and Industry

  • Trade restrictions and smuggling prevention

  • Migratory bird surveillance and testing

  • Stockpile of AI vaccine for poultry

  • Outreach and education

  • Quarantine and testing of legally imported birds


Supplemental ai funding l.jpg
Supplemental AI Funding Influenza

  • USDA received approximately $91 million

  • For domestic efforts, $73 million will help enhance and increase:

    • Wild bird surveillance and diagnostics

    • Animal vaccine stockpile

    • Biosecurity measures

    • Smuggling interdiction and trade compliance

    • Research and development

    • Planning, equipment, and training


Three hpai findings in the united states l.jpg
Three HPAI Findings in the United States Influenza

  • 1924 – “Fowl Plague” affected live bird markets in the Northeastern U.S

  • 1983 – destruction of 17 million birds in PA

  • 2004 – quickly contained and eradicated in TX


Avian influenza transmission l.jpg
Avian Influenza Transmission Influenza

  • AI is primarily spread by:

    • Direct contact between infected birds and healthy birds

    • Indirect contact with contaminated equipment and materials

  • Wild waterfowl are a natural reservoir for AI viruses

  • Airborne transmission from farm to farm is highly unlikely


Highly pathogenic ai in wild birds l.jpg
Highly Pathogenic AI in Wild Birds Influenza

  • Wild birds may play a role in moving HPAI

  • Asian H5N1 may be adapting to wild birds

  • Most outbreaks are likely due to the movement of poultry and poultry products


Wildlife monitoring l.jpg
Wildlife Monitoring Influenza

  • USDA and DOI sampling of migratory birds

  • Ongoing studies by USDA and university partners in Alaska

    • Over 12,000 samples with no evidence of HPAI

  • USDA’s National Wildlife Disease Surveillance and Emergency Response System


Wild bird highly pathogenic ai interagency working group l.jpg
Wild Bird Highly Pathogenic AI Interagency Working Group Influenza

  • Membership

    • USDA

    • DOI

    • HHS

    • State of Alaska

    • International Assoc. of Fish and Wildlife Agencies

    • National Assoc. of Public Health Veterinarians


Slide10 l.jpg
Draft U.S. Interagency Strategic Plan InfluenzaAn Early Detection System for Asian H5N1 Highly Pathogenic Avian Influenza in Wild Migratory Birds

  • Developed by wildlife biologists, veterinarians, and epidemiologists

  • Early detection is the key

  • Unified national system for conducting H5N1 monitoring and surveillance of migratory birds


Preparedness in the event of an outbreak l.jpg
Preparedness in the Event of an Outbreak Influenza

  • USDA’ comprehensive emergency response structure:

    • Partnerships with local, State, and Federal organizations

    • Integration with the National Response Plan

    • Continual collaboration with Federal entities

    • Diagnostic capabilities


Response in the event of an hpai outbreak l.jpg
Response in the Event of an HPAI Outbreak Influenza

  • Response actions for domestic flocks:

    • Quarantine and humane euthanasia

    • Cleaning and disinfection of premises

    • Possible use of vaccine in poultry

    • Indemnity payments

    • Communication to media and the public
