Public Health refers to the science that deals with the protection and improvement of the health and well-being of people and the community. It is concerned with protecting the health of the public, be it in a neighbourhood, a country, or a region of the world. Health not only means the absence of disease but it also includes the physical, psychological, and social wellbeing of people.

Public Health is an interdisciplinary field that draws from many other disciplines like social sciences, biology, epidemiology, and biostatistics. The study program includes researches conducted on public health issues, the creation of health policies, and undertaking educational activities to promote health and wellbeing. Students pursuing a degree in Public Health will be provided with solid knowledge about issues that impact the health of a population, healthcare systems, disease prevention, global health ethics, and environmental health issues.

People with Public Health degrees regularly work to keep people healthy and safe by preventing diseases and injury. They also take several initiatives to improve the overall well-being of society. These include vaccinations, clean air and water policies, suicide prevention, obesity education, smoking cessation, and family planning among many others. Public Health students develop useful communication, interpersonal, leadership, technical, and systematic thinking skills during their course.
