Relationships between monthly TBE cases in month n+1 and mean tick abundance in month n for all tick sampling sites within the region from which TBE cases are counted, for 2005 (green), 2006 (black) and 2007 (gold). Only the following show statistically significant correlations: a) Bern, Switzerland 2006, R² = 0.531, n = 9, p < 0.05 (correlation between TBE and ticks in concurrent months is stronger, R² = 0.781, n = 10, p < 0.01); b) Bavaria, Germany 2006, R² = 0.820, n = 11, p < 0.001; 2007, R² = 0.784, n = 11, p < 0.001; c) Slovenia 2006, R² = 0.532, n = 11, p < 0.05; 2007, R² = 0.369, n = 11, p < 0.05; h) Latvia 2006, R² = 0.639, n = 9, p < 0.01.
