Which statement best describes a disaster?

• A. An event that occurs gradually over years.
• B. An event typically occurring suddenly that causes damage, ecological disruption, loss of human life, or deterioration of health and health services that exceeds the capacity of the affected community on a scale sufficient to require outside assistance.
• C. A minor accident with no health impact.
• D. A planned event to test emergency response.

Answer: (B)

A disaster is a sudden event that causes significant damage and disruption beyond what a community can handle with its own resources, affecting health, safety, the environment, and requiring outside assistance. The statement captures the rapid onset, the scope of harm, the impact on health services and ecological systems, and the need for help from outside the affected area, which are the defining features of disasters.

The other options don’t fit because a gradual, years-long process isn’t a typical disaster; a minor accident with no health impact isn’t a disaster, and a planned drill is a simulation, not an actual disaster.
