Myths associated with disasters
• Any kind of assistance needed in disasters
• A response not based on impartial evaluation contributes to chaos. It
must be coordinated
• Epidemics and plagues are inevitable after every disaster
• Epidemics rarely may occur after a disaster, but can be avoided
• Dead bodies will not lead to catastrophic outbreaks of exotic disease
• Proper resumption of public health services will ensure the public’s
safety (sanitation, waste disposal, water quality, and food safety)
• Disasters bring out the worst in human behavior
• The majority responses spontaneous and generous
• The community is too shocked and helpless
• Cross-cultural dedication to common good is most common response to
natural disasters
Patterns of mortality and injury
• Disaster events that involve water are the most
significant in terms of mortality
• Floods, storm surges, and tsunamis all have a higher
proportion of deaths relative to injuries
• Earthquakes and events associated with high winds
tend to exhibit more injuries than deaths, as in Haiti
• The risk of injury and death is much higher in
developing countries – at least 10 times higher
because of little preparedness, poorer infrastructure.
Disaster and Health
• In a major disaster water treatment plants,
storage and pumping facilities, and distribution
lines could be damaged, interrupted or
contaminated.
• Communicable diseases outbreak due to:
• Changes affecting vector populations (increase
vector),
• Flooded sewer systems,
• The destruction of the health care infrastructure,
and
• The interruption of normal health services geared
towards communicable diseases
Disaster and health
• Injuries from the event
• Environmental exposure after the event (no
shelter)
• Malnutrition after the event (feeding the
population affected)
• Excess NCD mortality following a disaster
• Mental health (disaster
syndrome)
The Phases of Disaster
• Mitigation:
• Lessen the impact of a disaster before it strikes
• Preparedness:
• Activities undertaken to handle a disaster when it strikes
• Response:
• Search and rescue, clearing debris, and feeding and
sheltering victims (and responders if necessary).
• Recovery:
• Getting a community back to its pre-disaster status
Mental wellness
• In any major disaster, people want to know
where their loved ones are, nurses can assist in
making links.
• In case of loss, people need to mourn:
• Give them space,
• Find family friends or local healers to
encourage and support them
• Most are back to normal within 2 weeks
• About 1% - 3% may need additional help
Special considerations for children
• A child may be afraid of recurrence, injury, or death after an
earthquake.
• They may also fear being separated from their family or being
left alone.
• Children may even interpret disasters as punishment for real
or imagined misdeeds.
• Children will be less likely to experience prolonged fear or
anxiety if they know what to expect before, during, and after
an earthquake.
• Talking to children openly will also help them overcome fears
Special considerations for children
• Talking to children openly will also help them
overcome fears
• Return of children to school as early as possible
• Ensure appropriate nutrition and evaluate
nutritional status
Dangers of Tropical Diseases
Outbreaks
• Historically, infectious disease epidemics have
high mortality
• Disasters have potential for social disruption
and death
• Epidemics compounded when infrastructure
breaks down

Phases of a Disaster
(from an infectologic point of view)
• Impact Phase (0-4 days)
• Extrication
• Immediate soft tissue infections
• Post impact Phase (4 days- 4 weeks)
• Airborne, foodborne, waterborne and vector diseases
• Recovery phase (after 4 weeks)
• Those with long incubation and of chronic disease,
vectorborne
Current outbreak risks for Haiti
• Endemic organisms
• Post-impact phase
• Recovery Phase
Post-impact Phase Infections
• Crush and penetrating trauma
