Geographic classification Physical space Strategies for service delivery Instruments Health service Workforce composition Workforce tasks structure Duration of activities Workforce training Volunteer peoples 3

Population movement after the earthquake Zones Earthquake-stricken area 4

Population Movement Major concern and barrier for effective services delivery in Bam 1) Invasion of poor people from neighboring 2) areas to Bam 110, 000 Population before the earthquake - 40, 000 = Number of death (? ) 90, 000 Population at the 1. 5 months after the earthquake 5

Population Movement 2) Changing living places inside the bam The most important reasons: § Poor environmental health condition of previous living zone (85%) § Lack of accessibility to latrines (73%) § Recurrent referral of health personnel for census (54%) § Being interested in being in front of their own damaged house (49%)

Cumulative percent of the first time health services delivery to the earthquake-stricken households in Bam till 20 th days of post-disaster period 7

The overall satisfaction of the earthquakestricken people from health services delivery 8

Public address system: Psychological importance § Between families had asked for news about their relatives after the earthquake and used from provided list by governmental organization, 23% had found their response. 23

Mass Graves in Bam Myths and Realities § Political environment § Bad odor § Cultural beliefs 24

Surveillance System Current response Collection Modify of additional the system data Iterative process Evaluation the action Further action Additional analyses Disseminating the result 25

Evaluation of Designing Steps of the Surveillance System in Bam § Establishment of objectives § Development of case definitions § Determining data sources § Development of data-collection instruments § Testing the field § Development and testing of analysis strategy § Development of dissemination mechanism § Usefulness assessment of system 26

Pre-requirements of Surveillance System in disasters Stable health management in crises Epidemiologic Knowledge Well-trained field-team Network communication system 27

28

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
