Public health practitioner

Public health practitioners can have a huge influence on the health and wellbeing of individuals, groups, communities and populations. 

Working life

Public health practitioners work in many places and in many areas of public health. They may support healthy lifestyle programmes, helping individuals and groups to stop smoking and take more exercise. They may work on immunisation programmes and screening, based in local communities or in public health teams specialising in health protection.

Some public health practitioners may play an important role in national and local health campaigns. Others may work in the public health knowledge and intelligence teams in local government organisations and the Office for Health Improvement and Disparities.
