Public health represents a growing and dynamic field with opportunities to address the world’s most pressing health problems. The discipline is a combination of both the science and art of advancing the health of individuals, families, communities, and populations through education, promotion of healthy behaviors, and research for disease and injury prevention. A person’s health is defined not only by genetics and personal choices, it’s also determined by the environment. Public health is all around us—where we live, work and play impact our health.
