Ring Vaccination as a Control Strategy for Foot-and-Mouth Disease
Foot-and-Mouth disease (FMD) is a highly infectious illness of livestock and a serious economic threat. Effort has been placed in modeling various control strategies for eradicating the disease. In this study we will consider a spatial model that incorporates ring vaccination and isolation as a control measure for the dispersal of the epidemic. We found an upper and lower bound of the basic reproductive number for the spatial model in terms of our parameters. Through numerical simulations we were able to show that ring vaccinations is effective in controlling the epidemic. We validate our results by using the dataset based on the 2001 FMD epidemic in Uruguay.
