我们通过使用二维洪水模拟模型，定量研究了孟加拉国达卡市洪水条件与洪水引起的腹泻发病率之间的关系。我们在目标地区进行了洪水模拟，并将模拟结果与腹泻发病率进行了比较。通过家访发病率调查评估腹泻原因；这些调查在雨季的不同阶段（季风前、季风中和季风后）在达卡市洪水易发地区的10个低收入社区进行了三次，对象是5岁以下的儿童。结果显示，洪水影响腹泻的发病率，因为在季风季节中期，几乎所有社区的发病率都有所增加。然而，也发现了具有腹泻易感性的病例，如社会经济地位，因为在没有发生洪水的季风前和季风后季节观察到发病率。各季节最大洪涝深度为0.7 ~ 1.2 m的地区发病率高于最大洪涝深度为0.1 ~ 0.2 m的地区。因此，我们发现腹泻易感性的梯度受社会经济地位等诱发因素的影响，其影响在整个雨季都保持不变。
: We quantitatively investigated the relationship between flood conditions and the incidence of diarrhoea caused by flooding in Dhaka City, Bangladesh, by using a two-dimensional flood simulation model. We performed flooding simulation in target areas, and the simulated results were compared to diarrhoeal morbidity. Diarrhoea causes were assessed through home-visit morbidity surveys; these surveys were conducted three times in different phases of the rainy season (pre, mid and post-monsoon) in 10 low-income communities in flood-prone areas of Dhaka City, targeting children below five years of age. The results revealed that flooding influences the morbidity of diarrhoea, as increased morbidity was identified in almost all communities in the mid-monsoon season. However, cases with a predisposition of diarrhoea such as socioeconomic status were also identified, as morbidity was observed in pre- and post-monsoon seasons when flooding did not occur. Furthermore, morbidity was higher in areas with maximum flooding depth of 0.7– 1.2 m than that in areas with maximum flooding depth of 0.1–0.2 m in each season. Consequently, we found that the gradient of diarrhoeal vulnerability is affected by predisposing factors such as socioeconomic status, and its influence is maintained throughout the rainy season.
