What is Public Health?
As described by the American Public Health Association: Public health promotes and
protects the health of people and the communities where they live, learn, work and
play. While a doctor treats people who are sick, those of us working in public health
try to prevent people from getting sick or injured in the first place. We also promote
wellness by encouraging healthy behaviors.
From conducting scientific research to educating about health, people in the field
of public health work to assure the conditions in which people can be healthy. That
can mean vaccinating children and adults to prevent the spread of disease. Or educating
people about the risks of alcohol and tobacco. Public health sets safety standards
to protect workers and develops school nutrition programs to ensure kids have access
to healthy food.
Public health works to track disease outbreaks, prevent injuries and shed light on
why some of us are more likely to suffer from poor health than others. The many facets
of public health include speaking out for laws that promote smoke-free indoor air
and seat-belts, spreading the word about ways to stay healthy and giving science-based
solutions to problems.
