“…The same sequence of stages may be used for disasters: hyperacute (immediately following the event), acute (within 48 hours), subacute (within 2 weeks), chronic (following 2 weeks), and rehabilitation and recovery stages. 8 The duration of each stage may be variable depending on the type of disaster, as anticipated disasters such as hurricanes may permit early evacuation, thus shortening the subacute phase, while earthquakes will have a different timeline. As a general guideline, the non-chronic stages typically occur within the initial 2 weeks, while the chronic stages can extend for years.…”
