Public Health is the science and practice of protecting and improving the health of populations through prevention, education, policy, and research. It focuses on identifying health risks, implementing interventions, and evaluating outcomes at the community or population level rather than individual patient care.
Professionals in this field work across government agencies, non-profits, healthcare organizations, and academic institutions. Common roles include epidemiologists, public health analysts, health educators, and policy advisors. These experts address issues such as infectious disease control, environmental health, maternal and child health, substance abuse, and health equity.

Individuals with expertise in Public Health are expected to understand biostatistics, epidemiology, health services administration, environmental health sciences, and social and behavioral sciences. They often use data analysis tools, geographic information systems (GIS), and public health surveillance systems to monitor and address health concerns. A strong foundation in ethics, health disparities, and global health challenges is also essential. Most positions require at least a bachelor’s degree, with many roles preferring a Master of Public Health (MPH) or related graduate qualification.
