FAQ

Why is Public Health Sciences important?

Public health aims to improve the wellbeing of society as a whole and prevent illness – in contrast to hospital doctors, GPs and nurses who primarily look after individual patients on a case-by-case basis.

There are three main areas of public health:

• Health protection – working to prevent the outbreak of epidemics, plan responses to emergencies, or in food safety.
• Health improvement – campaigns to encourage healthier eating, physical exercise, or to persuade people to quit smoking and drugs.
• Healthcare public health – making sure that everyone has access to high-quality health services and medicines that they need, when they need them.
