The Disease Ecology and Computer Modeling Laboratory (DECML) with Rebecca Garabed (Preventive Veterinary Medicine), Ningchuan Xiao (Geography), and Song Liang (University of Florida), Mark Moritz (Anthropology) examines the ecology of infectious diseases in different projects in the USA, Cameroon, and Nicaragua. The lab started with a project that examined the epidemiology of infectious diseases in the ecological context of networks of host movements. Specifically, the goal is to understand the transmission and maintenance of Foot and Mouth Disease Viruses (FMDV) in networks of livestock movements in the Far North Region of Cameroon. Because FMD is endemic and vaccinations are not used, the region provides an unprecedented opportunity to examine how different networks of livestock movements affect disease epidemiology.
Data on disease incidence and prevalence was collected for four years in overlapping networks of livestock movement including daily foraging, annual transhumance, regional markets, and transboundary trade. The data is used to develop coupled models including a Susceptible-Infected-Recovered (SIR) model of infections within herds, an agent-based model of movement and connectivity between herds within and across networks, and molecular modeling to provide additional data and to validate the other models. We received funding from the Ecology and Evolution of Infectious Diseases (EEID) program at the National Science Foundation for this project and have developed other projects that examine the ecology of other infectious diseases, including cholera.
We are training graduate and undergraduate students from across Ohio State University (e.g., anthropology, city and regional planning, computer science, geography, mathematics, nutrition, public health, and veterinary medicine) as well as MA and Ph.D. students from the universities of Maroua and Ngaoundére in Cameroon.
