Epidemic Model of Foot-and-Mouth Disease with Vaccine

Abstract

Foot-and-Mouth Disease (FMD), an extremely infectious viral disease affecting clovenhooved animals, has been a problem in South Korea in the past few decades causing severe financial damages nationwide in the livestock industry. Despite that culling is the main prevention measure of the spreading of FMD, alternative measures like vaccination has been implemented; however, the efficacy and influence of this measure still remains to be examined. We establish a mathematical model which is an extension of the SIR model to examine the dynamics of FMD outbreak. An external source of infection is considered in the transmission process [1] to contemplate the repeated outbreaks in South Korea. In this work, we would like to explore the effects of different vaccination scenarios on the epidemics of FMD through simulations.
