Number of bank voles and Puumala virus (PUUV) strains at each trapping site per year, number of sequences for each PUUV genome segment (S/M/L) and the concatenated sequences (S, M, L), and PUUV prevalence in the bank voles. Asterisks indicate prevalence estimates based on vole sample sizes lower than 10.
