What is Public Health

Public health logo


What is the role of Public Health?

Public health plays a very important role in protecting, promoting, and maintaining the health of entire communities. These communities may be as small as your neighborhood, or as large as the whole country.

Many of public health's duties are health issues we face in everyday life-like protecting the drinking water, or ensuring the safety of food at local restaurants.

Public Health also has a role in areas like dental health, preventing injuries, preparing for emergencies and disasters, monitoring the leading causes of death, and preventing the spread of disease.

Our role is different than that of other health professionals because public health centers on prevention, while the medical community usually focuses on care for those who are already sick.
