Public health improves the quality of life, helps children thrive, reduces human suffering and saves money. Every day, the public health field is working to prevent hazards and keep people healthy. What’s the difference between health care and public health? The health care industry treats people who are sick, while public health aims to prevent people from getting sick or injured in the first place. Public health also focuses on entire populations, while health care focuses on individual patients.
