Animal and human movements can impact the transmission of infectious diseases. Recent outbreaks of infectious diseases such as Ebola Virus Disease, Middle Eastern Respiratory Syndrome, Severe Acute Respiratory Syndrome, or foot-and-mouth disease (FMD) occur across borders and concurrently in the world. Because the movements of individuals and goods occur globally and frequently, an infectious disease outbreak in one place can be spread throughout the world. Therefore, analyzing and predicting movements is closely related to predicting and preventing the spread of an epidemic. Analyzing historical epidemic data and modeling the spread of an epidemic allow us to prepare for new epidemics in the near future and can also be the basis of a policy decision. Modeling animal and human movements and their impacts, however, presents a significant challenge to disease transmission models because these models often assume a fully mixing population where individuals have an equal chance to contact each other. In reality, movements result in populations that can be best represented as dynamic networks whose structure changes over time as individual movements result in changing distances between individuals within a population. This dissertation models the impact of the movements of mobile pastoralists on FMD transmission in a transhumance system in the Far North Region of Cameroon. I first analyze transhumance survey data to derive mobility rules that can be used to simulate the movements of the agents in the model. I develop an agent-based model coupled with an epidemic model. With the model, I simulate under the different environments and various experiment scenarios to evaluate the impacts of mobile pastoralists’ regular movements and changes in the movement patterns on hypothetical FMD epidemics. My simulation results are validated with empirical data collected by surveying herders over the last four years (2010-2014).
