The Injury Severity Score (ISS) is an established medical score to assess trauma severity. [1] [2] It correlates with mortality, morbidity and hospitalization time after trauma. It is used to define the term major trauma. A major trauma (or polytrauma) is defined as the Injury Severity Score being greater than 15. [2]
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
The CFR for the Spanish (1918) flu was greater than 2.5%, while the Asian (1957-58) and Hong Kong (1968-69) flus both had a CFR of about 0.2%.

The Abbreviated Injury Scale (AIS) is an anatomical-based coding system created by the Association for the Advancement of Automotive Medicine to classify and describe the severity of injuries. [1] [2] [3] It represents the threat to life associated with the injury rather than the comprehensive assessment of the severity of the injury. [4]
A 1991 study showed that in confined spaces the relationship was significantly different: 1.2 minor injuries for each serious injury or death. [7] A broad study of UK accident data in the mid-1990s showed a relationship of 1 fatality to 207 major injuries, to 1,402 injuries causing three or more days lost time injuries, to 2,754 minor injuries.
