| Outline of Final Research Achievements |
This study aimed to develop a diarrhoea prediction model using environmental information extracted from satellite remote sensing. We developed a time-series regression model by applying a distributed lag non-linear model to concurrently describe the non-linear relationship between environmental factors and the number of diarrhoea cases over multiple weeks of lag. The number of weekly diarrhoea cases visiting hospitals around the Lake Victoria in Nyanza province, Kenya was revealed to be predictable using environmental data including land surface temperature, water surface temperature, normalized difference vegetation index (NDVI) around the hospital, area of high NDVI on the lake surface (as an index of floating water hyacinth) and rainfall that were extracted from the MODIS satellite images and the GSMap.
