AB The  typical  natural  history  of  diseases  and  conditions  dictates  that  at  some  point  the  biological  onset  of  the  disease  occurs  and  progresses  at  varying  rates  until  they  become  clinically  evident.  These  rates  may  be  as  short  as  instantaneous,  as  in  acute  trauma,  or  could  be  life-long,  as  in  a  genetic  risk  factor  for  Alzheimer's  disease.  Primary  prevention  attempts  to  intercept  the  conditions  that  lead  to  disease  onset,  while  secondary  prevention  generally  relates  to  the  early  and  asymptomatic  detection  of  disease;  that  is,  disease  screening,  in  the  hope  that  the  trajectory  toward  clinical  illness  can  be  stopped  or  mitigated  in  a  helpful  way.  When  overt  clinical  illness  is  present,  tertiary  prevention  refers  to  rehabilitative  and  other  factors  that  deter  disease  progression  and  help  return  the  patient  to  a  healthier  state.
