4.1  Levels of disease prevention

Prevention, as it relates to health, is really about avoiding disease before it starts. It has been defined as the plans for, and the measures taken, to prevent the onset of a disease or other health problem before the occurrence of the undesirable health event. There are three distinct levels of prevention, which you already met briefly in Study Session 2.
