In civilian usage the word "casualty" is properly used for a person who is killed, wounded or injured by some event. It is usually used to describe multiple deaths and injuries due to violent incidents or disasters. Casualties is sometimes loosely used to mean fatalities, but non-fatal injuries are also casualties.
