The February 2001 Earthquake in Gujarat..

Value of damage estimated as Rs 220 Crore (US$ 47 million) No losses were estimated at the time, that would have included the cost of treatment of (physically and psychologically) injured persons as well as the cost of monitoring and controlling outbreaks of diseases

Occurrence of Malaria After Quake

The Gujarat State Department of Health and Family Welfare reported an increased incidence of malaria cases after the disaster, due to

• An increased breeding of the vector

– Higher storage of drinking water due to irregular water supply – Many abandoned, partially-filled water tanks

Occurrence of Malaria After Quake..

• Occurrence of just above normal rainfall

rates after disaster

• Increassed human-vector contacts
• Population displacement after earthquake
• Labor migration from malaria-endemic

regions

Scope of Exercise to be Done

Workshop participants are requested to estimate the value of losses sustained after the earthquake due to the higher incidence of malaria in Kachchh District, brought about from neighboring areas where the disease is endemic, including

– The cost of treatment for malaria patients, and – The cost of vector control to reduce malaria incidence to normal levels

Assessment Process

Number of Patients Arising from ‘Quake Unit Treatment Costs Medical Treatment Costs = Losses Population at Risk In Affected Area Unit Costs for Vector Control Vector Control Costs = Losses

Total Losses: Medical Treatment + Vector Control

080808 RJovel 13

Steps for the Assessment

• 1. Define baseline for assessment

– Long term trends – Monthly variation of malaria incidence

• 2. Define number of cases due to disaster

– Plasmodium Vivax – Plasmodium Falciparum

• 3. Determine unit costs for treatment

– Outpatients – In hospital

• 4. Estimate total cost of treatment

Steps for the Assessment ..

5. Estimate losses due to vector control 6. Determine number of inhabitants in affected area

– Urban areas – Rural areas

7. Determine unit costs for vector control

– Urban areas – Rural areas

8. Estimate cost of vector control 9. Estimate total losses = treatment of patients + vector control

• 10. Compare value of estimated total losses versus

value of damage
