Why Study Public Health?

BECAUSE YOU CARE.

Public health is a field for people who care about the greater good of human beings.

If that sounds self-important, consider this: Millions of people are alive today thanks to a handful of public health initiatives, such as vaccination programs, motor vehicle safety laws, restrictions on the use of tobacco, family planning, and clean air and water standards.

The field of public health is constantly evolving in response to the needs of communities and populations around the world. The underlying mission of public health is to improve the conditions and behaviors that affect health so that all people can attain it. That mission includes not only the practice of public health policy, but the research of public health issues and the education of future leaders who eventually will translate that research into practices and policies to improve the health of people regionally, nationally, and globally.
