EEB events: Thursday seminar: Trouble where you least expect it: causes and consequences of disconnects between transmission and disease hotspots in a vector-borne wildlife disease: Dr. Andrew Park, University of Georgia
Andrew Park, Assistant Professor, Odum School of Ecology, Department of Infectious Diseases, College of Veterinary Medicine, University of Georgia
The “more transmission = more disease” paradigm is rightly a central concept in infectious disease science. However, there are mechanisms that can lead to more complicated relationships. Hemorrhagic disease in white-tailed deer (caused by a virus vectored by biting midges) displays evidence suggesting the parasite is most active (even maintained in a source-sink sense) in regions with little, or no disease. I will lay out the case for complex and cryptic transmission using surveillance data, seroprevalence studies, statistical and mechanistic models and sequence-based phylogeography. In addition to reflecting on the power of interdisciplinary science to shed light on disease ecology, I will review the potential for similar processes to operate widely in a range of disease systems along with the challenge that cryptic refuges for parasites brings regarding surveillance, intervention and inference.
Coffee and cookies will be served at 4 p.m.
