Public health covers three key areas:
Health Improvement: Involves work to improve the health and wellbeing of individuals and communities by promoting health lifestyle changes e.g. helping people to quit smoking, improving their living conditions, or promoting healthy eating, but also tackling underlying issues like poverty and reduced access to healthcare.
Health Protection: Involves ensuring the safety and quality of the environment, food and water, preventing the spread of communicable disease, and managing outbreaks e.g. pandemic flu, or addressing the health effects of climate change in the UK or abroad.
Healthcare: Helping to ensure that health and care services are fit-for-purpose and accessible by all sectors of the population.
