Urban exodus and the dynamics of COVID-19 pandemics

In mid-march in France following the announcement of containment of persons to their home, a number of city dwellers left to the country side. Countrymen were not enthusiastic in fear of contamination and this exodus was first strongly criticised in the media. Numerical simulations presented in the present paper show that the increase in infected persons in the countryside is over compensated by the decrease of the infection in cities. At the Nation level the effects of this urban exodus were then beneficial.
