Study Notes
Veterinary Epidemiology Surveillance
- Surveillance refers to the systematic collection, analysis, and interpretation of animal health-related events occurring in a population.
- Key elements of surveillance include:
- Objective of the surveillance program
- Defined case definition
- Unit of interest (e.g., individual animal, herd, or population)
- Diagnostic methods
- Target population
- Geographic location
- Timing of data collection
- Data collection and processing procedures
- Data analysis methods
- Communication and dissemination of results
- Passive Surveillance: Involves data collection through routine submissions to laboratories by veterinarians, case reporting by the public, and molecular surveillance to differentiate infections.
- Active Surveillance: Data is collected through structured population sampling with a defined objective. This can be done through disease prevalence surveys, risk-based surveillance, or sentinel surveillance.
- Risk-based surveillance utilizes epidemiological and economic principles to define surveillance program activities.
- Sentinel surveillance involves continuous monitoring of specific herds to detect outbreaks or disease introductions early.
- Syndromic Surveillance: Utilizes non-specific diagnostic indicators, such as a sudden decrease in reproductive performance, to quickly identify potential outbreaks.
- Surveillance Sensitivity and Specificity: The ability to detect a particular disease can be quantified.
- Monitoring is a wider term that refers to ongoing data collection to identify changes or trends in the occurrence of events.
- Surveillance objectives:
- Assess and manage risks to animal and public health
- Minimize adverse effects on trade in animals and animal products
- Early warning for new and emerging diseases
- Monitoring endemic diseases and their vectors
- Data analysis: Data collected through surveillance systems needs to be processed and analyzed to inform risk assessment and management.
- Surveillance system structure: Typically structured into separate programs each dealing with a specific outcome, and includes data collection components like laboratory services, border inspection, and slaughterhouse inspection.
