Economic epidemiology is a field at the intersection of epidemiology and economics. Its premise is to incorporate incentives for healthy behavior and their attendant behavioral responses into an epidemiological context to better understand how diseases are transmitted.
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.

Policy for population health "sets priorities" [2] and are a "guide to action to change what would otherwise occur". [2] Policies are based on "social sciences of sociology, economics, demography, public health, anthropology, and epidemiology" [4] and determine how outcomes can be accomplished are implemented at various levels.
In epidemiology, a non-pharmaceutical intervention (NPI) is any method used to reduce the spread of an epidemic disease without requiring pharmaceutical drug treatments. Examples of non-pharmaceutical interventions that reduce the spread of infectious diseases include wearing a face mask and staying away from sick people .
In statistics, econometrics, political science, epidemiology, and related disciplines, a regression discontinuity design (RDD) is a quasi-experimental pretest–posttest design that aims to determine the causal effects of interventions by assigning a cutoff or threshold above or below which an intervention is assigned.
Many theoretical studies of the population dynamics, structure and evolution of infectious diseases of plants and animals, including humans, are concerned with this problem. [27] Research topics include: antigenic shift; epidemiological networks; evolution and spread of resistance; immuno-epidemiology; intra-host dynamics; Pandemic; pathogen ...
In medical research, epidemiology, social science, and biology, a cross-sectional study (also known as a cross-sectional analysis, transverse study, prevalence study) is a type of observational study that analyzes data from a population, or a representative subset, at a specific point in time—that is, cross-sectional data.

A public health intervention is any effort or policy that attempts to improve mental and physical health on a population level.Public health interventions may be run by a variety of organizations, including governmental health departments and non-governmental organizations (NGOs).
