Public health


Public health aims to improve wellbeing and prevent illness. It includes public health protection, health improvement and health care.

There are three main areas of public health:

  • Health protection: protecting the population’s health by ensuring that environmental risks are minimised.
  • Health improvement: helping people to improve their own health, and therefore preventing illnesses from developing in the first place.
  • Health care: making sure that everyone has access to the high quality health services and medicines that they need, when they need them.
