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.
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.. It is a cornerstone of public health, and shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare.
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 to such circumstances.
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. [8]
In particular, public health surveillance programs can: [49] serve as an early warning system for impending public health emergencies; document the impact of an intervention, or track progress towards specified goals; and; monitor and clarify the epidemiology of health problems, allow priorities to be set, and inform health policy and strategies.
For example, epidemiological ABMs have been used to inform public health (nonpharmaceutical) interventions against the spread of SARS-CoV-2. [9] Epidemiological ABMs, in spite of their complexity and requiring high computational power, have been criticized for simplifying and unrealistic assumptions.
Behavioral diagnosis — This is the analysis of behavioral links to the goals or problems that are identified in the social or epidemiological diagnosis. The behavioral ascertainment of a health issue is understood, firstly, through those behaviors that exemplify the severity of the disease (e.g tobacco use among teenagers); secondly, through ...

A model is a way of presenting a situation in such a way that it shows the logical terms in order to showcase the structure of the original idea. The term nursing model cannot be used interchangeably with nursing theory.
