Injury, also known as physical trauma, is damage to the body caused by external force.[1] This may be caused by accidents, falls, hits, weapons, and other causes.[1] Major trauma is injury that has the potential to cause prolonged disability or death.
In 2013, 4.8 million people world-wide died from injuries, up from 4.3 million in 1990.[2] More than 30% of these deaths were transport-related injuries.[2] In 2013, 367,000 children under the age of five died from injuries, down from 766,000 in 1990.[2] Injuries are the cause of 9% of all deaths, and are the sixth-leading cause of death in the world.[3][4]
