Infectious Diseases

Public health is the science of defensive and educating the health of people and their communities. This work is attained by promoting healthy lifestyles, researching disease and injury prevention, and detecting, preventing and responding to infectious diseases. Public health professionals try to avoid problems from happening or recurring through executing educational programs, recommending policies, managing services and conducting research—in contrast to medical professionals like doctors and nurses, who focus mainly on treating individuals after they become sick or injured. Public health also works to limit health differences.
