An active surveillance system is one where health facilities are visited and health care providers and medical records are reviewed in order to identify a specific disease or condition. [3] Passive surveillance systems are less time-consuming and less expensive to run but risk under-reporting of some diseases. Active surveillance systems are ...
Disease surveillance is an epidemiological practice by which the spread of disease is monitored in order to establish patterns of progression. The main role of disease surveillance is to predict, observe, and minimize the harm caused by outbreak , epidemic , and pandemic situations, as well as increase knowledge about which factors contribute ...
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 ...
COVID-19 surveillance involves monitoring the spread of the coronavirus disease in order to establish the patterns of disease progression. The World Health Organization (WHO) recommends active surveillance , with focus of case finding, testing and contact tracing in all transmission scenarios. [ 1 ]
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 ...
Epidemiological (and other observational) studies typically highlight associations between exposures and outcomes, rather than causation. 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.

MMWR has its roots in the establishment of the Public Health Service (PHS). On January 3, 1896, the Public Health Service began publishing Public Health Reports.Morbidity and mortality statistics were published in Public Health Reports until January 20, 1950, when they were transferred to a new publication of the PHS National Office of Vital Statistics called the Weekly Morbidity Report.
Infection Control & Hospital Epidemiology is a peer-reviewed medical journal published by Cambridge University Press.It publishes research on control and evaluation of the transmission of pathogens in healthcare institutions and on the use of epidemiological principles and methods to evaluate and improve the delivery of care, including infection control practices, surveillance, cost-benefit ...
