Veterinary Epidemiology and Animal Health Risk Management
Utilizing various statistical tools and epidemiological parameters, the Veterinary Epidemiology and Animal Health (AH) perspective focuses on disease detection, mitigation, prevention, and prediction in livestock production systems. It addresses challenges such as product flows, profitability, and stakeholder perceptions to identify critical control points and optimize prevention and control measures. The approach involves assessing human health risks, economic costs, and key intervention opportunities, aiming to benefit smallholder pig sectors and consumers through targeted mitigations.

VCA from Animal Health (AH) perspective Vet Epidemiology AH Disease detection, mitigation, prevention & prediction Tools: Statistics & epidemiological parameters: sample size, statistical differences, correlations, prevalence s, case fatality, odds ratios Challenge: Product flows, drivers, profitability, incentives Variety of stakeholders (people, groups and organisations) in livestock production and marketing systems Different perceptions of the same risk May be affected in different ways (traders vs. producers) May react in different ways 1
VCA from AH perspective general comments Key questions to be answered: Who has most to gain or lose related to mitigation efforts Which processes within the chain carry risk for disease spread, what are their relative contributions to overall risk Where are the risk hotspots (e.g. for disease spread) When in the year are the high risk times (e.g. Ted, Ramadan) Where and when should prevention & control measures be targeted (identification of critical control points)? Policy environment (regulation-enforcement) 2
VCA from AH perspective - Approach Pig VC Work Vietnam Human health risks and economic costs of smallholder pig diseases What are the critical points / opportunities for risk management Mitigations which benefit small holder pig sector and poor consumer Project site: 2 project sites 3 VC gradients (rural-rural, rural-peri-urban, peri-urban) Suggested approach Review (Yr 1) Rapid assessment (Yr 1) In-depth assessment (Yr 1 & 2) Interventions (Yr 3 - ...) Dissemination (Yr 4 - 5) 3
VCA from AH perspective - Approach Review (year 1) Tools: Outputs: Currently AH constraint list of important pathogens Surveillance, policies What has worked and what has not Challenge: several hundred pathogens including zoonoses & FBD How to reasonable scale it down to 1-3 Different perception on AH constraints (e.g. Small holder versus large scale, latter perhaps favourites by governments) Official/grey literature & projects Rapid assessment (year 1) Tools: FGD, interviews, observations, check list Outputs: Diseases of concerns - key AH constraints (reduced to 2-3) Description of situation, basic flows and actors involved Basic pathways mapped First idea on possible intervention opportunities 4
VCA from AH perspective - Approach In-depth assessment (integrated disease risk and economic survey) (year 1 & 2) Tools: Cross-sectional, longitudinal, producer + other actors Biological sampling, FGD, questionnaires, check list ... (aligned with Public Health and socio-economics) Target: Producers, slaughterhouses (spot check and over time) Veterinary health workers (disease reports) Outputs: Disease impact (prevalence, mortality, treatment costs, indirect/direct losses...) Detailed risk pathways/risk assessment, control points, Set of promising interventions (Having in mind what worked and what has not) Interventions (Yr 3 onwards) Set of intervention packages Randomised control trials aligned WTP, WTC 5
VCA from AH perspective Pig VC Vietnam - Challenges Different constraints - different actors involved & perceptions Production constraints Feed supply (input sector and producer) Production disease (producer, life animal trader, input system) Zoonoses ) However, perhaps not From farm to fork ) attractive for producer, FBD ) as productivity still Entire chain, farm to fork ) reasonable (input sector/producer) slaughterhouse - trader consumer 6
