Study Notes
Purpose of Surveillance
- The purpose of surveillance is to collect and analyze data to understand the distribution and determinants of health-related events.
Investigating Outbreaks
- Outbreak investigation involves the coordinated effort of several persons to characterize the extent of an outbreak and identify its cause.
Surveillance Data Sources
- Surveillance data comes from various sources, including death certificates, disease registers, and laboratory reports.
Surveillance Cycle
- The surveillance cycle refers to the continuous process of data collection, analysis, and dissemination.
Epidemiology
- The primary purpose of epidemiology is to understand the distribution and determinants of health-related events.
- Epidemiologists rely on clinical physicians and lab scientists for proper diagnosis of individual patients.
- Epidemiological information is used in daily personal decisions to make informed choices about health behaviors.
Epidemiology Goals
- The primary goal of epidemiology is to prevent disease and promote health.
- The first step in solving health problems is to describe the problem through descriptive epidemiology.
Epidemiologist Roles
- A key function of epidemiologists is to identify the causes of health problems.
- Epidemiologists play a crucial role in evaluating treatment methods and prevention strategies.
Types of Epidemiology
- Chronic epidemiology deals with diseases that develop slowly and may persist for long periods of time.
Infectious Diseases
- The chronic disease era proposed a theory that diseases develop due to the interaction between agent, host, and environment.
- Descriptive epidemiology focuses on the distribution of disease, including time, place, and person.
Analytic Epidemiology
- Analytic epidemiology aims to identify the causes of health problems.
Pathogen and Pathogenesis
- The term "pathogen" refers to any disease-causing organism or substance.
- Pathogenesis refers to the pattern of response by a living organism to invasion by a foreign substance or injury.
- Virulence refers to the potential ability and strength of a pathogenic substance to cause disease.
- Infection refers to the entry and development or multiplication of an infectious agent in a host.
Test your knowledge about the core functions of epidemiology including surveillance, field investigation, policy development, analytic studies, linkages, and evaluation. Understand the purpose of surveillance in depicting patterns of disease occurrence and potential.
