Simulation exercise
A simulation exercise (SimEx[1] ) or emergency preparedness exercise[2] is a public health simulation of a hypothetical disaster used to test response capacity. It is similar to military exercises.
Types
[edit ]The World Health Organization categorises simulation exercises into four categories: tabletop exercise, drill, functional exercise, and full-scale exercise listed in increasing complexity (amount of preparation and resources required).[3] The European Centre for Disease Prevention and Control considers an additional type: the orientation exercise which it places before tabletop exercise.[4] . The discussion-based exercises (orientation and tabletop[4] are recommended as a starting point before conducting operation-based exercises (the other three types).[2]
Format
[edit ]During an exercise, injects are provided.[5] These are updates to the scenario in the form of emails, news articles, telephone calls and so on.[6] The master scenario events list contains an overview of which injects are used when.[7] The exercise is followed up by a debrief, including a "hot" debrief immediately after the exercise.[8]
Scenarios
[edit ]Disease outbreaks
[edit ]NSW Health hosted an influenza pandemic exercise called XFG in 2008.[9] The World Health Organization hosted an exercise in 2025 called Polaris[10] . The fictional disease being tested was "mammothpox"[11] [12] The outbreak started with a pathogen from permafrost [12] . The same year, UK Health Security Agency held an exercise called Pegasus.[13] The fictional disease in this exercise was "EV-D68".[14]
| Name | Year | Facilitator | Disease |
|---|---|---|---|
| Exercise Cygnus | 2016 | UK Government | influenza |
| Exercise Alice | 2016 | UK Government | Middle East respiratory syndrome |
| Exercise Clade X | 2018 | Johns Hopkins Center for Health Security | disease X |
| Crimson Contagion | 2019 | US Department of Health and Human Services | influenza |
Mass casualty events
[edit ]In 2017 an exercise called Elsa considered a major incident leading to many casualties.[2] The same year, an exercise named Socrates considered a mass casualty event.[2]
Natural disasters
[edit ]A 2011 simulation imagined the 365 Crete earthquake happening again.[15] In 2012 an exercise simulating destruction of the Isthmus of Corinth as a result of an earthquake was held.[16]
