Why is epidemiology important to community health?
Epidemiology saves lives and improves global, long-term health. The aims of epidemiology are to prevent and reverse negative health outcomes, and the uses of epidemiology are most important for communities that experience a lot of poverty or instability.
How does epidemiology help public health?
It is the scientific method of investigation problem-solving used by disease detectives— epidemiologists, laboratory scientists, statisticians, physicians and other health care providers, and public health professionals—to get to the root of health problems and outbreaks in a community.
How can epidemiological data assist you when identifying health problems in a community?
Measures the progress of control and prevention programs. Enables generation of testable hypotheses regarding the etiology, exposure mode, control measure effectiveness, and other aspects of the health problem. Helps validate the eventual incrimination of causes or risk factors.
How epidemiology is related to community health?

What are the objectives of disease surveillance?
Information from surveillance systems can be used to monitor the burden of a disease over time, detect changes in disease occurrence (e.g., outbreaks), determine risk factors for the disease and populations at greatest risk, guide immediate public health actions for individual patients or the community, guide programs …
Why is tracking diseases so important?

What are the three objectives of any disease investigation?
The specific objectives of an investigation are to define the parameters of the epidemic (i.e., time of illness onset and conclusion of the epidemic, number of cases, and morbidity and mortality), to identify control or prevention measures, and possibly to identify new data relative to the epidemiology of the health …
What is the role of surveillance in public health?
