by State Welfare Organization

Mental health interventions in Bam

Office of Mental Health at Iranian MOH has

valuable experiences on MH interventions

in disaster situations, based on previous

earthquakes in Iran.

They are covering all population in Bam

by holding “Relief groups” to deal with

PTSD, Depression and Suicide.19

Some comments on the Disease Surveillance System in Bam

Necessity of effective training program

Improving effective communication system, especially internet

Surrounding area should not be missed

Integration of a JIT Outbreak Investigation System

Using available data on referrals to clinics and health centers instead of the population for denominator of the indicators accompany by providing necessary information on referral pattern of people. 29

Future Potential Risk Factors of Outbreaks in Bam

Hot weather

Re-establishment of pipe-water supplies

Low access to bathing facilities and risk of pediculosis and other cutaneous diseases

Past history of epidemics of typhoid fever and cholera

Endemicity of malaria and coetaneous leshmaniasis 30

Final Conclusion of the lecture:

Bam earthquake was a major disaster,

resulting in mass destruction and a very

high toll on human lives and health.

These losses cannot be justified in light

of existing scientific knowledge and

expertise in disaster management. 31

Final Conclusion of the lecture:

The necessity of research-based

information and better multi-disciplinary

coordination was evident for more efficient

service deliveries to poor people.

Most of what can be done to mitigate

injuries must be done before an

earthquake occurs. 32

Final Conclusion of the lecture:

Because structural collapse is the single

greatest risk factor, priority should be given to

seismic safety in land-use planning and in the

design and construction of safer buildings.

The reconstruction of buildings according to

modern standards will take decades to

accomplish and will absorb a considerable part

of the country's resources.33

Final Conclusion of the lecture:

In disaster-prone areas, training and education in

basic first aid and rescue methods should be an

integral part of any community preparedness

program.

Better epidemiologic knowledge of risk factors

for death and the type of injuries and illnesses

caused by earthquakes is clearly an essential

requirement for determining what relief

supplies, equipment, and personnel are

needed to respond effectively to earthquakes. 34

Final Conclusion of the lecture:

The integration of epidemiologic studies

with those of other disciplines such as

engineering, architecture, the social

sciences and other medical sciences is

essential for improved understanding of

consequences following earthquakes. 35
