The role of aquatic reservoir fluctuations in long-term cholera patterns

► We model the impact of fluctuations of water availability on cholera epidemiology. ► The seasonality of water input drives the variation of concentration of bacteria. ► The model can reproduce characteristics of disease insurgence and persistence. ► We explore the influence of parameters on model behavior through bifurcation analysis. ► The emerging chaotic patterns resemble actual data on long-term cholera insurgence.
