The World Health Organization (WHO) defines Public Health science as “the art and science of preventing disease, prolonging health through the organized efforts of society.”
Public Health Science is the study of preventing disease, increasing the longevity of life and promoting health through efforts and choices made by society, public and private organizations, the community and by individuals.
Public Health Science deals with dangers to the public health of a population, whether small or large (i.e. populations of a continent) to improve the quality of health and the quality of life in through detecting and preventing disease and other physical and mental health conditions, promoting health behaviours, tracking cases and health indicators.
Public health students develop the critical thinking and analysis skills necessary to confront issues such as low vaccination rates, foodborne diseases and drug overdoses.
