In this study, the risk assessment technique of pathogens was applied to a compound disaster of a large earthquake with a flood and an evaluation method of the infection risk was proposed. The infection risks of the norovirus and cholera vibrio were calculated quantitatively using the Kanda River basin as the study area. The spatial distribution of the infection risk was created and the visualization of the infection risk was investigated. The results showed that the infection risk changes in a range of 1.2 to 10 times higher than usual in the case of a large earthquake with a flood and subsequent inland inundation.
