Hazard map of waterborne infection disease in the Mekong flood using the hydraulic and dose-response model

摘要

Coliform movement was simulated using the hydraulic flood model around Phnom Penh in Cambodia. The distribution of coliform concentration was evaluated by dose-response model and the impact on human health was investigated by the relationship between coliform amount and the mortality ratio of childs under 5 years old spatially. The results obtained are as follows; The risk of infection is higher in the rural region with long inundation period. The risk is locally lower in the rainy season, but the extent of inundation area with infection risk is spreading.
