Levels of Intervention

Levels of Intervention

  • Primary - seeks to prevent disease or injury through reduction of risk factors.  This can be active (requiring individuals to act - ex. mandating vaccination before school entry) or passive (changing the default to a healthier option - ex. flouridation of water).   
  • Secondary - early detection of disease such as through screening of individuals (ex. mobile mammogram programs) or data collection and reporting (ex. reportable diseases sent from hospitals to local or state public health)  
  • Tertiary - once the disease or injury exists, reducing the impact (ex. isolating someone who is contagious to prevent spread to others) or improving the health outcomes (ex. maintenance of diabetes through healthy eating education programs)
