Why Study Public Health?

Public health professionals work on improving the health of populations, especially through efforts to prevent illness and injury.

The field takes a broad approach and significant work is aimed at understanding and addressing the social determinants of health (e.g., housing, food security, education access, air and water quality, economic opportunity). This approach is different from clinical medicine where patients are seen one at a time and there is often a focus on treatment of conditions. Importantly, professionals in public health and clinicians regularly share information and work together to optimize prevention, early detection and treatment. 

Since public health is a broad field, there is an opportunity to pursue areas that you find most interesting. You may be passionate about working with certain populations, like children or immigrants, or you may enjoy developing creative materials for social media campaigns that promote healthy behaviors. Alternatively, you might enjoy conducting research that provides new insight into preventing injuries or developing compelling summaries for policy makers that explain how a proposed policy would reduce food insecurity in your state.
