Course name: Principles of Epidemiology, Disease Control and Prevention
Course codes: BAP 2102 Credit units: 4
This course covers the epidemiology of farm animal diseases and it importance in disease control.
• To explain disease causation and determinants
• To explain basic epidemiologic principles in disease investigation, prevention and control
• To understand, define and calculate different measures of disease occurrences
• To apply appropriate epidemiologic studies in research
By the end of this course, students should be able to:
• Understand the concepts in epidemiology of disease in farm animals.
• Explain the different disease transmission patterns of diseases in farm animals.
• Conceptualise aspects of disease control, monitoring and surveillance and disease reporting.
Introduction, definition of epidemiology, uses and sub disciplines Disease causation (postulates, reservoirs, sources, modes of transmission, susceptible hosts, etc). Factors contributing to emergence and re emergence of diseases. Principles of disease prevention and control methods, (eradication of disease reservoirs; disease eradication campaigns, test and slaughter, depopulation, quarantine and isolation. Types of associations, Associations between determinants and disease, hypothesis formulation. Introduction to epidemiological triad. Agent, host determinants and environmental determinants of disease. Distribution of disease events. Temporal distribution of disease events – epidemic curves, cyclic nature of epidemics, seasonal variations, etc, Spatial distribution of disease events (spotmaps, frequency maps, isodermic maps, etc). Introduction to GIS and its applications in veterinary epidemiology. Measures/Quantifying of disease populations. Definitions of rates, proportions, ratios. Prevalence & incidence rates. Other rates (morbidity, mortality, proportional mortality and mortality rates, case fatality, maternal mortality rates etc). Evaluation of serological tests (specificity, sensitivity, predictive values, false negatives and false positive), screening tests Considerations in the design of epidemiologic studies – comparison of field and laboratory studies. Epidemiological study designs (Experimental vs observational studies). Disease outbreak investigation, integrated disease surveillance and monitoring. Intervention studies-Controlled/Field trials. Introduction to participatory and environmental epidemiology. Participatory epidemiology methodologies.
