Study Notes
Introduction to Epidemiology (EPI 213)
- Epidemiology is the study of disease spread and prevention
- It examines disease transmission (person-to-person, animal-to-person, environmental) and factors like age, sex, and health impacting susceptibility.
- Epidemiologists develop interventions (vaccination, health education, environmental changes) to prevent diseases.
Course Description
- Introduces epidemiological concepts for students
- Covers types of epidemiological studies and associated issues
- Introduces basic epidemiological principles and methods, using examples of communicable and non-communicable diseases
- Includes measures of health and epidemiological study designs.
- Discusses course development strategies (e.g., increased use of IT/web resources, content updates based on new research).
Course Objectives
- Understand fundamental principles and concepts of epidemiology
- Define and utilize epidemiology’s applications and measures of disease frequency (prevalence, incidence)
- Learn the steps involved in disease outbreak investigations
- Understand the uses of different study designs
- Describe disease transmission concepts
- Identify epidemiological indicators for disease monitoring
- Explain methods in descriptive, analytical, and experimental epidemiological studies, applying these methods to improve healthcare service planning and delivery.
Assessment
- Quiz (Week 5): 10%
- Midterm Exam (Week 7): 25%
- Presentation/Assignment (Week 9): 10%
- Final Exam (Scheduled): 50%
- Participation (Throughout): 5%
What is Epidemiology?
- Epidemiology studies the distribution and determinants of health-related states or events in populations.
- The word originates from Greek: "epi" (upon) and "demos" (people).
- It's a valuable tool for public health professionals understanding health and disease factors, and developing preventive measures and strategies.
- Epidemiology is a key component of public health initiatives.
Epidemiologist
- A public health professional studying the distribution and determinants of health and disease in populations.
- Epidemiologists develop health improvement strategies.
- They work in various settings (public health agencies, hospitals, universities, research institutes, etc).
History of Epidemiology
- Key figure: John Snow (1854) – studied cholera outbreak in London, revolutionizing disease transmission understanding.
- Key figure: Richard Doll (1950s) – studied the link between smoking and lung cancer.
Importance of Epidemiology
- Identifying disease causes
- Developing and evaluating public health interventions
- Monitoring population health
- Planning & allocating healthcare resources
- Shaping public health policy
Uses of Epidemiology
- Identifying disease risk factors (lifestyle, environmental)
- Evaluating intervention effectiveness (vaccinations, treatments)
- Tracking disease spread (outbreaks)
- Planning and evaluating public health programs
- Making future health trend predictions
Areas/Fields of Epidemiology
- Public health (prevention & control)
- Clinical medicine (diagnosis & treatment support)
- Research (disease causes, new interventions)
- Government (policy development & implementation)
- Industry (pharmaceutical & health product development)
- Non-profit organizations (promoting health through programs).
