Deaths associated with natural disasters, particularly rapid-onset disasters, are overwhelmingly due to blunt trauma, crush-related injuries, or drowning.

The risk for outbreaks is often presumed to be very high in the chaos that follows natural disasters, a fear likely derived from a perceived misconception of association between dead bodies and epidemics. The availability of safe water and sanitation facilities, the degree of crowding, the underlying health status of the population, and the availability of healthcare services all interact within the context of the local disease ecology to influence the risk for communicable diseases and death in the affected population.
