Version 1.3 of the AHRQ Hospital Surge Model includes 13 scenarios.

Biological

  1. The covert release of aerosol Bacillus anthracis through a city.
  2. The covert release of smallpox virus in a large indoor theater.
  3. A pandemic flu outbreak that spreads across the country.1
  4. The covert release of airborne Yersinia pestis, producing rapidly progressing cases of pneumonic plague.

These four scenarios include both communicable and noncommunicable diseases; diseases that are treatable and not treatable with antibiotics; and indoor and outdoor attacks. The flu scenario incorporates hospital resource utilization and patient outcomes similar to those documented during the 2009 influenza A (H1N1) pandemic.

Chemical

  1. The overt explosion of a liquid chlorine tank in a densely populated suburb.
  2. The overt release of the blister agent sulfur mustard at a large outdoor event.
  3. The semi-covert release of the nerve agent sarin in a crowded arena.

These three scenarios include both indoor and outdoor scenarios, as well as attacks with toxic industrial chemicals, blister agents, and nerve agents.

Radiological/Nuclear

  1. The overt detonation of 1KT of nuclear material (improvised nuclear device) in a city center.
  2. The overt detonation of 10KT of nuclear material (improvised nuclear device) in a city center.
  3. The overt release of cesium-137 dust (commonly referred to as a "dirty bomb" or radiological dispersal device) in a city center.
  4. The covert placement of a cesium-137 point source in a public place.

These four scenarios include threats posed by radionuclides, which can be dispersed in an extremely violent reaction (nuclear), more gently (radiological dispersal device), or not at all (radioactive point source).

Foodborne

  1. The contamination of several ingredients of a popular food product with botulinum toxin. This product is then processed at the factory and distributed nationwide.

Conventional

  1. Terrorists place small-scale improvised explosive devices in several subway stations during rush hour.
