AB Chronic wasting disease (CWD) occurs naturally in 3 species of North American deer (Odocoileus spp.) and elk (Cervus elaphus nelsoni). As the only prion disease known to infect free-ranging wildlife species, CWD presents a challenge to global efforts to understand, control, and perhaps eliminate animal TSEs. CWD is contagious, and its epidemiology resembles that of scrapie. Horizontal transmission sustains CWD epidemics, but mechanisms remain under study. The extent and severity of CWD epidemics have been estimated via a combination of surveillance methods, including clinical case collection, harvest survey, and tonsil biopsy. Survey data have provided insights into temporal dynamics and spatial heterogeneity of CWD epidemics, as well as potential influences of animal density and movements and land use patterns on epidemic patterns. Recently, strategies for managing infected deer and elk herds have been devised based on analyses of field data and epidemic modeling. A few promising approaches are under evaluation, and results will be used to refine these strategies over time. This iterative process of modeling, managing, measuring, and analyzing responses comprises an adaptive management paradigm that is the foundation of efforts to control CWD in Colorado and elsewhere.
