Study Notes

Definition of Public Health

Public health is defined as the science and art of preventing disease, prolonging life, and promoting health.
It involves organized efforts and informed choices by society, organizations, and individuals.

Public Health Approach

Risk factor identification is essential for effective intervention.
Surveillance is crucial for monitoring and evaluation in public health.
Implementation of strategies is necessary for addressing health issues.

Epidemiology as a Science

Epidemiology is a quantitative discipline combining knowledge of probability, statistics, and research methods.
It employs causal reasoning through hypothesis development and testing across various scientific fields including biology and behavioral sciences.
Aims to explain health-related behaviors, states, and events.

Cholera and Public Health

Cholera was a significant health crisis in 19th-century London, resulting in tens of thousands of deaths due to contaminated water.
The prevailing belief at the time was that cholera was caused by "bad air".

John Snow's Contributions

John Snow is regarded as the father of modern epidemiology.
He traced the cholera outbreak's source and demonstrated that contaminated water was the critical factor in transmission.

Interventions and Evaluations

Snow's research highlighted that stopping exposure to contaminated water was essential for controlling the cholera outbreak.
Comprehensive evaluations of interventions were crucial for successful public health strategies.

Understanding Epidemiology

The term epidemiology derives from Greek, meaning the study of diseases in populations.
Investigates the factors determining disease occurrence.

Veterinary Epidemiology

Focuses on the investigation of diseases, productivity, and animal welfare within animal populations.
It describes the frequency of disease and its impact due to various determinants.

Applications of Epidemiology

Aids in determining the unknown origins of diseases.
Facilitates investigation and control of poorly understood diseases.
Enhances knowledge of disease ecology and natural history.
Supports planning, monitoring, and assessment of disease control programs.
Evaluates economic impacts of diseases and their control measures.
Informs individual health decisions.

Goals of Veterinary Epidemiology

Targets disease control, reduction of productivity losses, and improvement of animal welfare.
