Public Health

Public health professionals try to prevent problems from happening or recurring through implementing educational programs, recommending policies, administering services, and conducting research—in contrast to clinical professionals like doctors and nurses, who focus primarily on treating individuals after they become sick or injured. Public health also works to limit health disparities. A large part of public health is promoting health care equity, quality, and accessibility.
