Temporal prevalences of Echinococcus multilocularis and Taenia taeniaeformis strobilocerci in 4 study areas. a) Prevalences and 95% confidence intervals of Echinococcus multilocularis (undifferentiated and protoscoleces-containing metacestodes), b) prevalences and 95% confidence intervals of Taenia taeniaeformis strobilocerci. Overall prevalence rates per area are symbolised by circles. For E. multilocularis, the number of voles with protoscoleces and the total number of studied individuals are given above the associated bars (N total = 856 Arvicola terrestris). Study areas are shown in Figure 1.
