Livestock Movements and Disease Transmission in the Chad Basin: Modeling Risks for Animals and Humans


Dr. Mark Moritz, Department of Anthropology
Rank at time of award: Assistant Professor


Our team is seeking IPR seed grant funds to support a pilot study of the ecology of cholera
in the city of Maroua, Cameroon, which will allow us to write competitive proposals for NSF and NIH. The goal of the study is to examine why some neighborhoods have higher incidence rates of cholera than others and what the role of demographic, human health behavior, and environmental risk factors is. We will use an interdisciplinary approach, integrating spatial, ethnographic, epidemiological, and microbial analyses to better understand the ecology of infectious diseases in urban settings in sub-­‐Saharan Africa. Initially, we will focus on cholera, which is endemic in the Far North Province of Cameroon, but our study is designed such that we can use the same dataset – surveys of households and water management – in future studies of other diseases that spread through contaminated water, such as typhoid and hepatitis A. We are particularly interested in the research question whether cholera is endemic in Maroua due to environmental reservoirs or whether it is constantly reintroduced due to migratory movements of individuals traveling to and from the border regions of Nigeria (see also Dowell and Braden 2011; Piarroux et al. 2011). A greater understanding of the dynamics of the disease, will contribute to more effective control of cholera in the region.
