An accidental injury is an unintentional harm that occurs to a person's body due to an unexpected event or incident. This type of injury can result from various causes such as falls, motor vehicle accidents, contact sports, exposure to chemicals or radiation, and other types of mishaps. Accidental injuries can range in severity from minor cuts and bruises to life-threatening conditions such as head trauma, spinal cord injury, or organ damage. The key characteristic of an accidental injury is that it was not intentionally inflicted by another person, but rather occurred due to circumstances beyond the victim's control.
