| We present some recent work in modeling the spatial dynamics of cholera, a waterborne infectious disease that remains a significant public health burden in developing countries. An emphasis of this study is the interplay of biological, environmental and physical factors which shape the complex pattern of cholera epidemics. Particularly, the effects of the intrinsic bacterial growth, direct and indirect disease transmission pathways, and host and bacterial movement are investigated. Traveling wave solutions and disease threshold dynamics will be discussed, and both analytical and numerical results will be presented. |
