What we do

Public Health is “the science and art of preventing disease, prolonging life and promoting, protecting and improving health through the organised efforts of society” (Acheson, 1988).

Public health professionals use epidemiology - a statistical science - to describe the occurrence of disease and what the causes might be - much of this work is "behind the scenes".  The more we understand about the cause of diseases, the more we can do to prevent them; detect them at an early stage; or provide the most appropriate health services.
