What is Public Health?
Public health is the science of protecting and improving the health of families and communities through promotion of healthy lifestyles, disease and injury prevention, and the detection and control of infectious diseases.
Public health helps improve the health and well being of entire populations. These populations can be as small as a local neighborhood, or as big as an entire country. It is the science and art of promoting health by understanding the processes of health including: social, mental, spiritual and physical well-being. Public health professionals strive to improve the health of communities through education, promotion of healthy lifestyles, and research for disease and injury prevention.
