Hello and welcome to this video where we are going to talk about “Public Health”!
“Public health” has made a significant impact on the health of populations…….making
people healthy and saving lives. For example, in the United States,
between 1900 to1999, people’s life expectancy has increased by over 30 years…
Did you know that 25 of these “extra years” gained are due to public health interventions?!
So in this video, we are going to take a look at what public health is,
how it is different to clinical medicine, who is responsible for doing it and how it’s done!
First of all…let’s have a look at what “health” is.
The World Health Organization defines health as “a state of complete physical,
mental and social well-being rather than a mere absence of disease or infirmity.”
This is a pretty bold and ambitious definition that prompts people to look beyond diseases and
focus not only on the physical aspect of health but also the mental and social aspects as well.
…..and public health?? Well…..public health is the science and art of
preventing disease, prolonging life, and promoting health through the organized efforts of society.
