Definitions Injury “Acute exposure to physical agents such as mechanical energy, heat, electricity, chemicals, and ionising radiation interacting with the body in amounts or at rates that exceed the threshold of human tolerance. In some cases, injuries result from the sudden lack of essential agents such as oxygen or heat.” (Source: Gibson, 1961; Haddon, 1963) 10/11/20152N.ALAMRO - COMM 311
Definitions Violence “The intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community, that either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment or deprivation.” (Source: WHO, 1996) 10/11/20153N.ALAMRO - COMM 311
The Global Injury Problem 5 million deaths worldwide = 9% of all deaths (2000) 12% of global burden of disease Road traffic “incidents” are the leading cause of injury deaths worldwide 90% of injury deaths occur in low- and middle- income countries Highest number of deaths in S.E. Asia & Western Pacific regions 10/11/20154N.ALAMRO - COMM 311
