Public Health Courses overview
Public health is the science of improving the quality and quantity of life. It refers to the measures that are taken to increase overall health, to prevent disease, and to analyse the factors that both contribute to and take away from living a healthy life.
True health is something holistic and multidimensional. Health is something that affects us on both individual and social levels. This is reflected in the United Nations definition of health, which is "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity”.
The populations and organisations that consume and create public health policy are just as varied. Far from being relegated to hospitals and doctors offices, public health encompasses any place, practice or culture that affects our well-being. This includes environmental factors, community atmosphere, mental health, workplace health, and so much more.
Is public health for me?
A degree in public health could be for you if you hope to improve the world and the quality of life of your fellow citizens. Public health allows people to contribute to the overall well-being of the community - it doesn’t matter if you are not suited to a career in straight biomedicine.

Employment options

Health policymaker
Someone who works in health policy is responsible for creating the plans and actions that will lead to a specific health outcome.

Health communications and health promotion
Are you good at convincing people to better their health? A career in health promotion and health communication seeks to communicate health information in a contextual way in order to improve the understanding of health.
