Figure 1 is a line graph depicting the temporal change in the number of notifications of suspected TSE cases that are added to the CJD Registry, by year (1997-2013) and jurisdiction (ACT, NSW, NT, etc). Generally, the number of suspected case notifications by state and territory align with population size with some annual fluctuations. While the annual number of nation-wide suspect case notifications in 2013 was consistent with the figures observed in 2012, notifications were 37% lower compared with the long-term average for the years 1993 to 2012. By state and territory, fewer notifications from Victoria, Western Australia and Tasmania were received during 2013 and this was also observed during the previous year. Coupled with lower notifications recorded in Queensland in 2013, it is estimated that an additional 20-30 cases per year have not been notified to the ANCJDR during 2012 and 2013. Notifications from New South Wales increased modestly returning to expected levels, while the remaining states and territories remained unchanged from the previous year. While fluctuations are to be expected with annual CJD notifications, it should be noted that since 2006, notifications have been consistently declining in Western Australia.
