Study on spread of vibrio cholera in rivers based on Cellular Automata Model

Cholera is an infectious disease, which begins abruptly, spreads fast, influences a wide range and is easy to outbreak, but traditional way of monitoring epidemic trends of cholera is of lag because of the incubation period and period from treatment to diagnosis. In order to improve cholerae surveillance and to show early warning of cholera epidemic in time, a growth and reproduction model of vibrio cholera based on improved Cellular Automata Model, is created and verified. According to the model, diffusion of vibrio cholera in river is simulated, integrated with multi-source data including remote sensing inversion data, hydro-geomorphological data, basic geographical data, monitored environmental data and monitored bacteria data.
