Each of these sectors contributes to the four basic components of surveillance, which are (1) collection, (2) analysis, (3) dissemination, and (4) response. Collection and analysis can be conducted at the local, state, federal, or international level by public agencies as well as by private industry.
What are two key characteristics of a good surveillance system?
Simplicity refers to the system’s structure and ease of operation. Flexibility is the ability of the system to adapt to changing information needs and operating conditions with minimal additional cost. Data quality is the completeness and validity of the data collected through the system.
What are characteristics of surveillance?
Timeliness, to implement effective control measures; Representation, to provide an accurate picture of the temporal trend of the disease; Sensitivity, to allow identification of individual persons with disease to facilitate treatment; quarantine, or other appropriate control measures; and.
What attributes characterize a good surveillance system?
Subsequent sections focus on the attributes of a surveillance system (simplicity, flexibility, acceptability, sensitivity, predictive value positive, representativeness, and timeliness) and demonstrate how these combine to affect the usefulness and cost of a system.
What is process of surveillance?

What are surveillance methods?
This can include observation from a distance by means of electronic equipment, such as closed-circuit television (CCTV), or interception of electronically transmitted information like Internet traffic. It can also include simple technical methods, such as human intelligence gathering and postal interception.
What is effective surveillance?
An effective disease surveillance system is essential to detecting disease outbreaks quickly before they spread, cost lives and become difficult to control. Effective surveillance can improve disease outbreak detection in emergency settings, such as in countries in conflict or following a natural disaster.
What are the attributes of surveillance?
The attributes and costs of a surveillance system are interdependent….Evaluate the system for each of the following attributes:
- Simplicity.
- Flexibility.
- Acceptability.
- Sensitivity.
- Predictive value positive.
- Representativeness.
- Timeliness.
What are the parameters of a health surveillance system?
Parameters for measuring the importance of a health event–and, therefore, the surveillance system with which it is monitored–include: Total number of cases, incidence, and prevalence Indices of severity, e.g., the case-fatality ratio An index of lost productivity, e.g., bed-disability days
How is surveillance used in a criminal investigation?
Surveillance is a critical tool in any investigation, often requested to get details that a client wants. When performed correctly, a Private Investigator can find plenty of information taking this approach, but the methodology is a key factor in conducting surveillance.
What are the dangers of being under surveillance?
