The science of public health is concerned with the protection and enhancement of people's and communities' health and well-being.  It is focused with safeguarding the public's health, whether in a neighbourhood, a country, or a globe area. Health encompasses not just the absence of sickness, but also people's physical, psychological, and social well-being.

Public health is an interdisciplinary study that depends on many other disciplines such as social sciences, biology, epidemiology, and biostatistics. The study programme covers research on public health concerns, the development of health policies, and the implementation of educational initiatives to improve health and well-being. Students seeking a degree in Public Health will get strong understanding of issues affecting population health, healthcare systems, disease prevention, global health ethics, and environmental health challenges.

People with a degree in public health work to keep people healthy and safe by helping them to avoid disease and harm. They also take many steps to promote society's general well-being. Vaccinations, clean air and water legislation, suicide prevention, obesity education, smoking cessation, and family planning are just a few examples. During their studies in public health, students teach important communication, interpersonal, leadership, technical, and systematic thinking skills.
