Study Notes
Epidemiology in Veterinary Science
- Epidemiology is the science of study and analysis of the distribution (who, when, and where) and determinants of health and disease conditions in defined populations.
- Epidemiology is not exclusively the study of infectious diseases in populations.
Principles of Epidemiology
- Study designs:
- Descriptive (no comparison)
- Analytical (comparison)
- Experimental (control over variables)
- Observational (no control over variables)
- Cross-sectional (one point in time)
- Cohort (longitudinal, forward timeline)
- Measures of disease frequency:
- Rates (e.g., mortality rate: 5 deaths per 100 dog-year)
- Numerator: the number of animals to whom something happened during a period
- Denominator: the population at risk during this period
- Surveillance:
- Ongoing systematic collection, analysis, and interpretation of health data
- Purpose: to detect and respond to health threats
- Compartment model of infectious diseases:
- SIR model: Susceptible → Infected → Recovered
- Other models: Carrier, Susceptible, Infected, Infectious, Shedder, Diseased, Recovered
- Causation in Epidemiology:
- Strength of the association
- Consistency of findings
- Temporal sequence of association (exposure must precede outcome)
- Biological plausibility
- Experiment (removal of exposure alters frequency of outcome)
Importance of Epidemiology in Veterinary Practice
- Understanding the epidemiology of diseases (e.g., skin cancer in white cats, hip dysplasia in German Shepherds, Spirocerca lupi in southern USA)
- Identifying risk factors and susceptible hosts
- Informing prevention and control strategies
- Improving diagnostic processes
Key Concepts
- Susceptible host: Breed, age, sex, genotype, physiology, and susceptibility
- Infectious disease: Pathogen, pathogenicity, dispersal efficiency, survival efficiency, inoculation dose
- Environment: Housing management, population density, sanitation, nutrition
- Prevention: Importance in veterinary practice
