Public health is the science and art of creating healthy communities through education, research and promotion of healthy lifestyles. In public health, the focus is on health promotion and disease/injury prevention, in contrast to the medical model of care, which focuses more heavily upon diagnosing and treating illnesses and conditions after they occur.

Public health professionals analyze and develop programs that protect the health of individuals, families and communities in the United States and abroad. The United States is placing a high priority on building up the nation's public health workforce.

A career in public health opens the door to diverse opportunities in a variety of sectors such as federal, private and non-governmental organizations. Because of their "big picture" perspective, public health experts play a key role in emergency preparedness and response. This may be why public health has become such a growing field in recent years.
