Abstract
Market Analysis Public health is the science and practice of protecting and improving the health of a community through education, disease and injury prevention, wellness promotion and protection of health. From scientific research to health education, the field of public health strives to improve the lives and social conditions that affect the health of a community. It is because of public health that we understand that second-hand smoke can cause cancer that bicycle helmets can save lives, and that dirty water can carry bacteria that cause disease.
