Relationship between research & application truth”

Application

Research

  • Disease control is well suited as an area ofinterface between research and application.

  • It is the Danish experience, that animal disease control is a fruitful research area – for the benefit of all parties.

  • Results of this applied research typically have national or international impact.

Research truth”

Application

  • problem-oriented

  • communicable

  • applicable


The role of official authorities in animal disease control preben willeberg dvm ph d dr vet sc dr vet sc h c professor chief veterinary officer

Examples truth” from animal disease control:

Disease mapping & spatial analysis

Risk assessment

Risk factor analysis

Research

Application

  • problem-oriented

  • communicable

  • applicable

  • structured problem

  • funded activity

  • transparent and objective data

International Risk Analysis Concept truth”

  • Risk assessment

    • Scientific discipline

  • Risk management

    • Practical discipline

    • Political influence

  • Risk communication

    • Consumer involvement

Epidemiology and Risk Analysis truth”

  • Animal health risk analysis relies on epidemiology

  • The risk of risk analysis to become merely a probabilistic exercise

  • Veterinary epidemiology ensures biological coherence in the risk analysis process

Risk Analysis Cyclus truth”

Surveillance

Epidemiological evaluation/

Risk assessment

Risk Analysis Process truth”

With epidemiology

  • Hazard identification

  • Risk assessment

  • Risk management

  • Risk communication

Without epidemiology

  • Enthusiasm

  • Skepticism

  • Mistrust

  • Depression

International animal health standards truth”

  • OIE International Animal Health Code

    • Guidelines for:

      • Risk Analysis

      • Regionalization

      • Surveillance

      • Evaluation of veterinary services

International animal health standards truth”

  • OIE International Animal Health Code

    • List of transmissible diseases (2004)

      • Criteria (2004)

        • International spread

        • Zoonotic

        • Emerging

        • Sign. spread in naive populations



Eu commission guidelines
EU Commission Guidelines truth”

  • DRAFT 2004 ”Animal Disease Eradication, Control and Monitoring Programmes” : Criteria for the evaluation of animal diseases with the purpose of drawing a list of diseases eligible for Community co-financing

  • At least one of the following criteria should be fulfilled:

    • Animal diseases with an impact on public health (zoonoses)

    • International spread (serious, rapid, socio-economic, public health, international trade)

    • Emerging diseases (newly recognized , different behaviour, spread, consequences)

    • Significance in international trade (export, free-trade agreements)

    • Significance in intra-Community trade (placing on the marked)


Danish bvdv strategy
Danish BVDV Strategy truth”

  • Danish Cattle Federation wants to eradicate BVDV

  • Danish Veterinary and Food Administration (DVFA) and Danish Cattle Federation worked out a control plan based on scientific knowledge

  • Danish Cattle Federation administers the plan supported by DFVA


Inputs
Inputs truth”

  • Herd owners - the veterinary practitioner:

    - within-herd tests

  • Danish Cattle Federation:

    - examination of milk and blood surveillance tests
