The public health tends to counter threats to the general health of a social circle on the basis of the analysis of population health.

The given population may be a few people or it might consist of all the residents of many continents, the example of a pandemic may be considered in this regard. there are many sub-fields for Public health, nevertheless the important ones are biostatistics, health services and the interdisciplinary categories of epidemiology, community health, Environmental Health, occupational health and behavioral health are also well-known organs of public health.

The idea behind public health's interventions is to avoid and control medical conditions, wounds and other health problems by extending close monitoring of cases and communities, environments (in areas pertaining to human health) and the promotion of healthy behavior. Its objective is to prevent health conditions from occurring or re-appearing by projecting administering services,educational programs, conductingresearch and other developingpolicies.
