Public health is the science and art of preventing disease, prolonging life, and promoting health through the organised efforts of society.
The public health workforce delivers a range of work to protect and improve the health of populations at local, regional, national, and global level.
Public health is the science and art of preventing disease, prolonging life, and promoting health through the organised efforts of society. It also considers principles of social justice and equity, promoting and protecting better health for all, leaving no-one behind. This means that public health holds a resolute focus on tackling inequalities in health, including those driven by racism and discrimination.
Rather than focussing on the health of the individual, public health works to protect and improve the health of communities and populations at local, regional, national, and global level.
Public health is a shared responsibility requiring collective action. As well as the specialist public health workforce, initiatives to improve public health may be delivered by governments, charities, community leaders, and businesses.
Examples of public health work include controlling infections, programmes to diagnose disease as early as possible, programmes to support healthy behaviours, ensuring people have access to nutritious food and safe housing, tackling climate change, and responding to major incidents and disasters.
The shared aim of the diverse range of public health work is to offer populations the best chance to live long lives in good health.
