Study Notes
Public Health and Epidemiology
- Public health encompasses collective efforts to enhance the health of populations.
- Epidemiology functions as a vital tool in public health, focusing on health-related events in populations.
Definition of Epidemiology
- Defined as the study of distribution and determinants of health-related states or events in specified populations.
- Application of epidemiological knowledge is essential for controlling health problems.
Uses of Epidemiology
- Determines the natural progression of diseases.
- Aids in planning and developing health services and programs.
- Provides critical administrative data for health authorities.
Objectives of Epidemiology
- Investigates the causes or etiology of diseases, disorders, and disabilities.
- Identifies primary agents and causative factors of health conditions.
- Analyzes characteristics of agents or causative factors.
- Examines modes of transmission for diseases.
- Studies contributing factors to health issues.
- Maps geographic patterns related to specific diseases.
Purpose of Epidemiology
- Establishes a foundation for creating disease control and prevention strategies targeting at-risk groups.
Application in Public Health Practice
- Discovers interacting factors: agent, host, and environment affecting health.
- Assesses the relative significance of causes leading to illness, disability, and mortality.
- Identifies population segments at greater risk for specific health concerns.
- Evaluates health programs' effectiveness in improving community health outcomes.
Scope of Epidemiology
- Originated from studying outbreaks of communicable diseases and their interactions among agents, hosts, vectors, and reservoirs.
- Enhanced ability to control disease spread through strategies like surveillance, prevention, quarantine, and treatment.
- Recognizes circumstances that may trigger epidemics, such as warfare, migration, famine, and natural disasters.
Natural History and Prognosis
- Focuses on the natural history of diseases and expected outcomes in both individuals and groups.
- Prognosis relates to the disease course post-intervention, influencing treatment discussions with patients.
- Investigates the presence of asymptomatic (sub-clinical) disease stages, which can enhance the effectiveness of treatment through early detection, paving the way for screening programs.
