Public Health

Public Health can be defined simply as the science and art of preventing disease.[1]

Public health can also be said to be the science of protecting and improving the health of people and their communities, achieved by promoting healthy lifestyles, researching disease and injury prevention, and detecting, preventing and responding to infectious diseases.[2]

Overall, public health is concerned with protecting the health of entire populations. These populations can be as small as a local neighbourhood, or as big as an entire country or region of the world.
