Abstract
The focus of this paper is to model the spread of COVID-19 within a multi-patch environment. The proposed model incorporates the short- term mobility and it is incorporated with the mobility matrix. A SQIHR model including close contact tracing incorporated with human mobility within patches is discussed. Different scenarios of the imposed mobility restrictions are illustrated with the numerical simulations for the early stage of disease spread in Sri Lanka. The spread of the disease from a hot spot to the local areas with no initial disease is numerically illustrated in this paper. Furthermore, the effetiveness of the close contact tracing of an infected patient is also addressed in this paper.

Keywords
Keywords: COVID-19, multi-patch compartmental model, mobility matrix, contact-tracing, mobility restrictions.
