Figure 5.

Virus prevalence at the different sampling sites. Overview of all PCR screening results shows that many of the detected viruses are found in different developmental stages and locations of origin. TBEV and Norway luteo-like virus 4 were not detected by PCR in any of the screened pools. Percentages shown here are likely over- or under-representations of the true values due to pooling of ticks (1–10 for nymphs/larvae) during extraction and limited counts for some of the developmental stages/locations. The number of screened extracts for each location/developmental stage is shown between brackets. A full overview of all screening results can be found in Supplementary Table S1.
