What are the four classifications of casualties in a disaster?

• A. Primary victim, secondary victim, bystander, rescuer.
• B. Injured, ill, missing, deceased.
• C. Direct victim, indirect victim, displaced person, and refugee.
• D. Immediate casualty, deferred casualty, long-term casualty, none.

Answer: (C)

In disasters, casualties are categorized to guide how responders allocate resources and coordinate care. Direct victims are those who suffer injuries or death caused directly by the hazard itself, such as someone trapped in a collapsed structure. Indirect victims are people affected by the event’s consequences even if they weren’t injured—like family members, witnesses, or those whose livelihoods are disrupted. Displaced persons are those who must move within the country because their homes are unsafe, while refugees are those who cross international borders seeking safety and protection. This fourfold classification helps responders tailor medical care for the injured, provide shelter and basic needs for those who have lost homes, and coordinate international support for refugees. Other terms in the alternatives don’t capture this range, since they mix medical status with roles like bystander or rescuer or use timing descriptors that don’t reflect the full scope of who is impacted.
