Overview of the presentation
• Definition and Brief History of PE
• Participatory Epidemiology (PE)
• Applications of PE
• Participatory Disease Surveillance (PDS)
• Attributes of PE/PDS Programs
• Participatory Epidemiology Network for Animal and
Public Health (PENAPH)
• First PE Technical Workshop, Chiang Mai, Dec 11-13,
2012
Participatory Epidemiology
The use of participatory rural appraisal
techniques to collect epidemiological
knowledge and intelligence
Participatory Rural Appraisal
(PRA)
• Qualitative intelligence
gathering process
• Key informants
• Iterative
• Problem-solving
• Decision-making
• Best-bet scenarios
Participation
• The empowerment of people to find solutions to their own development challenges
• Both an attitude and philosophy
– Learning
– Discovery
– Flexibility
• A response to past failures
Origins of PE
• NGO and development experts enter into animal health programmes – Climate of innovation
– Needs assessments and program design using PRA
– New insights
• Conventional science sceptical – Anecdotal vs. qualitative inquiry
– Difficult to publish
– Results of PE applications changed perceptions
• Widely practiced technique – Not a panacea
– Fit-to-purpose
Existing Veterinary Knowledge
• Traditional terms and
case definitions
• Clinical presentation
• Pathology
• Vectors
• Reservoirs
• Epidemiologic
features
Tools
• Secondary sources
• Direct observation
• Semi-structured interviews
– Checklists vs. questionnaires
– Open-ended questions
• Discovery
• Non-leading
– Probing
• Visualization - mapping
• Scoring - piling
• Key diagnostics
Applications of PE
• Needs Assessments – Priorities
– Entry points
• Participatory Epi Research – Basic epi studies
– Disease modelling
– Risk assessment
• Impact Assessment – Epidemiological
– Livelihoods
– Well-being
• Strategy and Policy Reform – More direct link between
decision-makers and the livestock owners
Applications of PE
• Community-based Disease Reporting
• Participatory Disease Surveillance – Case finding
– Disease freedom
– Community assessments • RP, FMD, PPR
• RVF,CSF, HPAI
– Fit-to-purpose

Entry Points and Incentives
Participatory Disease
Surveillance
• Targeted surveillance done by professionals
• Risk-based
• Highly sensitive – Traditional information
networks
– Extended time frame
• Specificity – Validation
– Cross-checking
– Diagnostic testing

Example from
participatory mapping
from Indonesia
Integrating PDS into surveillance
• Surveillance assessment and plan
• Surveillance fit-to-purpose
• Define objectives – National priorities
• Optimal balance of attributes – Sensitivity, timeliness, etc.
• Optimal mix of activities
Attributes of PE/PDS Programs
– Flexible approach that allows for discovery
– Practitioners are problem-solvers and not enumerators
– Strength of the approach lies in its flexible and qualitative nature
– Orients and complements, but does not replace structured and quantitative methods
– Information from diverse sources and methods
– Analyzed in an iterative process referred to as triangulation
– Integrates daignostic testing and quantitative methods when appropriate to objectives
Lessons
• Use PE/PDS for its strengths
– Flexibility and discovery vs. standardization
• Institutionalization
– Organizations and rules of the game
– What is the objective?
• An accepted problem solving tool or a
• Structured routine to fill databases?
• Invest in expert teams
– Focus on quality not quantity of personnel
Appropriate Combinations of
Complimentary Techniques
• Participatory approaches
• Diagnostic testing
• Analytical methods
Persistence as a Function of Initial Herd Immunity
