A sentinel surveillance system is used to obtain data about a particular disease that cannot be obtained through a passive system such as summarizing standard public health reports. Data collected in a well-designed sentinel system can be used to signal trends, identify outbreaks and monitor disease burden, providing a rapid, economical ...
Syndromic surveillance is the analysis of medical data to detect or anticipate disease outbreaks. According to a CDC definition, "the term 'syndromic surveillance' applies to surveillance using health-related data that precede diagnosis and signal a sufficient probability of a case or an outbreak to warrant further public health response.
The following is a partial list of the "N" codes for Medical Subject Headings (MeSH), as defined by the United States National Library of Medicine (NLM).. This list continues the information at List of MeSH codes (N04).

While some consider this a limitation of observational research, epidemiological models of causation (e.g. Bradford Hill criteria) [7] contend that an entire body of evidence is needed before determining if an association is truly causal.

The reorganized Institute was established to develop a national centre for teaching and research in various disciplines of epidemiology and control of communicable diseases. The Institute was envisaged to act as a centre par excellence for providing multi disciplinary and integrated expertise in the control of communicable disease.
Epidemiology is the study and analysis of the distribution (who, when, and where), patterns and determinants of health and disease conditions in a defined population, and application of this knowledge to prevent diseases.
At the federal Centers for Disease Control and Prevention in US states like Atlanta, Georgia, the Public Health Surveillance and Informatics Program Office (PHSIPO) focuses on advancing the state of information science and applies digital information technologies to aid in the detection and management of diseases and syndromes in individuals ...
Use of surveillance data for research is being improved through Web-based access to the data and analytic tools, and linking with other national data sources. For example, a web-based tool for public health officials and policy makers, State Cancer Profiles, [ 5 ] provides a user-friendly interface for finding cancer statistics for specific ...
