What are the two types of surveillance used in epidemiology?
These two types of public health surveillance – event-based surveillance and indicator-based surveillance – complement one another. Both types of surveillance include collecting, monitoring, assessing, and interpreting data. However, the types of data used and the situations in which we use them can be different.
What are the components of a surveillance system in epidemiology?
Infectious disease surveillance concurrently involves the health care delivery system, the public health laboratory, and epidemiologists. Each of these sectors contributes to the four basic components of surveillance, which are (1) collection, (2) analysis, (3) dissemination, and (4) response.
What are the types of surveillance systems?
Surveillance for Specific Conditions
- Environmental Public Health Surveillance.
- Injury Surveillance.
- Surveillance for Biologic Terrorism.
- Complex Emergency Surveillance.
- Surveillance in Refugee Populations.
- Chronic Disease Surveillance Systems.
What is the main purpose of epidemiologic surveillance?
The purpose of public health surveillance, which is sometimes called “information for action,” (18) is to portray the ongoing patterns of disease occurrence and disease potential so that investigation, control, and prevention measures can be applied efficiently and effectively.
What are surveillance systems?
A video surveillance system / CCTV is composed of a system of cameras, monitors/display units, and recorders. Cameras may be either analog or digital with a host of possible design features which will be discussed momentarily. These systems can be applied to both interior and exterior areas of a building or property.
What are the types of surveillance in epidemiology?
Types of Surveillance: (a) A focused location for surveillance (such as health facility-based surveillance or community based surveillance). (b) A designated or representative health facility or reporting site for early warning of epidemic or pandemic events (sentinel surveillance).
How does disease surveillance relate to epidemiology?
Evolving epidemiology of disease, the increasing prevalence of antimicrobial drug resistance, and the development of new vaccines and prophylactic treatments have each contributed to create the ongoing need for surveillance of international travelers. The risk of travel-related illness varies depending on destination and traveler characteristics.
What is epidemiological surveillance?
Epidemiological Surveillance.
