【 摘 要 】

We propose and analyse a mathematical model for cholera considering vaccination. Weshow that the model is epidemiologically and mathematically well posed and prove the existenceand uniqueness of disease-free and endemic equilibrium points. The basic reproduction number isdetermined and the local asymptotic stability of equilibria is studied. The biggest cholera outbreak ofworld’s history began on 27^th April 2017, in Yemen. Between 27^th April 2017 and 15th April 2018there were 2 275 deaths due to this epidemic. A vaccination campaign began on 6^th May 2018 andended on 15^th May 2018. We show that our model is able to describe well this outbreak. Moreover, weprove that the number of infected individuals would have been much lower provided the vaccinationcampaign had begun earlier.
