Occupational Risk Pyramid for Pandemic Influenza

Pyramid going from very high, high, medium, to lower risk (caution)

Very High Exposure Risk:

  • Healthcare employees (for example, doctors, nurses, dentists) performing aerosol-generating procedures on known or suspected pandemic patients (for example, cough induction procedures, bronchoscopies, some dental procedures, or invasive specimen collection).
  • Healthcare or laboratory personnel collecting or handling specimens from known or suspected pandemic patients (for example, manipulating cultures from known or suspected pandemic influenza patients).

High Exposure Risk:

  • Healthcare delivery and support staff exposed to known or suspected pandemic patients (for example, doctors, nurses, and other hospital staff that must enter patients’ rooms).
  • Medical transport of known or suspected pandemic patients in enclosed vehicles (for example, emergency medical technicians).
  • Performing autopsies on known or suspected pandemic patients (for example, morgue and mortuary employees).

Medium Exposure Risk:

  • Employees with high-frequency contact with the general population (such as schools, high population density work environments, and some high volume retail).

Lower Exposure Risk (Caution):

  • Employees who have minimal occupational contact with the general public and other coworkers (for example, office employees).
