Prevalence Goals Strategies Methods truth”


know and reduce occurrence

prevent spread

reduce impact

control of disease agent, diseased hosts, risk factors

improve resistance

survey, RF study, disease mapping

strategic vaccination




know occurrence and eradicate

prevent spread

low-tolerance system of disease control/eradication

surveillance (model-assisted) strategic vaccination, quarantine, movement control, zoning


know and reduce risk of introduction

be prepared

contingency plans awareness & capacity

risk mitigation


risk analysis, outbreak simulation exercises

documenting freedom

Animal Disease Control Logic


Scientific and technological factors truth”

Political, legal and financial factors

Structural and organisational factors

Animal Disease Control

between research and application

Risk Analysis

sharing and distributing responsibilities

International rules

OIE and EU

National issues


Co-operation with industry


Relationship between research & application truth”



  • 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”


  • problem-oriented

  • communicable

  • applicable

Examples truth” from animal disease control:

Disease mapping & spatial analysis

Risk assessment

Risk factor analysis



  • 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”


Epidemiological evaluation/

Risk assessment

Risk management


Risk communication

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 truth”

  • Herd owners - the veterinary practitioner:

    - within-herd tests

  • Danish Cattle Federation:

    - examination of milk and blood surveillance tests

    - aid to re-infected herds

    - compensation for culled PI-animals

    - personnel to administer the plan

  • DVFA:

    - supporting personnel and regulation
