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.
