Explain the difference between public health and public health practice

Public health is an organized societal effort to promote, protect, improve, and, when necessary, restore the health of individuals, specified groups, or the entire population. It is a way of thinking, a set of disciplines, an institution of society, and a manner of practice. Public health practice involves the application of knowledge, skills, and competencies to perform essential public health services and other activities to improve the population's health. Public health practice is about the art of doing public health, just as the practice of medicine is about the art of doing medicine.
