What are injuries?

Injuries are bodily harm – fatal or nonfatal - that can be caused by fires, motor vehicle crashes, drowning, sharp objects, firearms, being struck by an object, tripping and falling, pedestrian injuries and more.  Injuries may be unintentional (sometimes referred to as “accidental”), self-related harm or assault-related.  Poisonings, which include drug overdoses, are also a type of injury.
