Human Prion Disease and Relative Risk Associated with Chronic Wasting Disease
Figure 2. Colorado deaths 1979–2001 (left axis) with Creutzfeldt-Jakob disease (CJD) listed as the direct or contributory cause on the death certificate with age category at death identified by the plotting symbols 12–30 years (), 31–55 years(∆), 56–70 years () and >70 years (↓). Indicators of CWD-endemic county resident (black circle), female (–), and black (X) or other ( | ) race are also identified. On the basis of these death certificate data and Colorado demographic data (34), we also display a smoothed CJD death rate per million population over time (right axis) (∙ – ∙).
