PUBLIC HEALTH

Public health is the science of protecting and improving the health of communities and populations through organized efforts like promoting healthy lifestyles, researching disease and injury prevention, and responding to epidemics. It focuses on preventing illness on a large scale, rather than treating individuals like a doctor's office does, and includes activities such as disease surveillance, health education, and policy development. Public health is crucial for creating the conditions where people can be healthy and is achieved through the combined efforts of governments, organizations, and communities.
