What Are The Three Core Functions Of Public Health


The responsibility of local health departments is to protect and promote health, prevent illness and injury. Public health services are population-centered – that is, services that are focused on improving people’s health status, as opposed to primary care providers, who respond to treatment of particular individuals.

To accomplish this mission, public health departments balance the three public health functions of the central government. These three functions are essential for maintaining population-centered services.
