Number of PCV2 sequences and haplotypes per genotype per year. The columns represent the numbers of PCV2 sequences per genotype per year (PCV2a – dark blue, PCV2b – dark red, PCV2d – dark green, PCV2g – pink) and the number of PCV2 haplotypes (HT) per genotype per year (PCV2a – light blue, PCV2b – light red, PCV2d – light green, PCV2g – rose)
