What is Public Health?

Public Health is the science and art of protecting and improving the health of communities through education, promotion of healthy lifestyles, and research for disease and injury prevention.

Public health helps improve the health and well being of people in local communities and across our nation.

Why is it important?

The dramatic achievements of Public Health in the 20th century have improved our quality of life: an increase in life expectancy, world wide reduction in infant and child mortality, and the elimination or reduction of many communicable diseases.

In 1999, the Centers for Disease Control and Prevention named the ten greatest public health achievements of the 20th century. These advances have been largely responsible for increasing the life span of populations; over twenty-five of the thirty years can be accredited to public health initiatives, while medical advances account for less than four years. Furthermore, since 1900, the average life expectancy for Americans has increased by about thirty years.
