Field Overview
Public Health is an interdisciplinary healthcare field focused on protecting, promoting, and improving the health of whole populations and communities—rather than treating individual patients in clinical settings. Public health professionals analyze disease trends, enforce environmental sanitation, implement health policies, and direct disease prevention campaigns.
Students master epidemiology, biostatistics, environmental health, global health systems, and social determinants of health. Guided by global agencies like the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), public health specialists safeguard populations against epidemics and health inequities.
