Researchers say this new model will require expertise and collaboration across fields such as veterinary and human medicine, disease ecology, biodiversity conservation, biotechnology and anthropology. (phys.org)
Recently, for example, in collaboration with colleagues in the Department, we have analysed all publically available epidemiologic and genetic data to ascertain under-reporting and selection bias in the ongoing epidemic of MERS-CoV, as well as the transmission scenario for this virus.
