  • Illness amongst the public that can occur naturally, (such as flu), or is man-made, (such as and intentional release of anthrax)
  • Illness amongst the public that may cause a larger number of deaths and/or serious disabilities
  • Illness due to a hard to control infectious agent, (such as flu)
  • Illness due to a chemical attack on the public, (such as cyanide gas)
  • Illness due to release of nuclear material, (such as radiology materials used in hospitals)
