Temporal and spatial distribution of BVDV-1 genotypes in France. A Proportion of genotypes over time in France. Genotyping data include current and previous studies (1994–1998: Vilček et al., 2001 [13], 2004–2005: Jackova et al., 2008 [12]; 2018–2020: Rivas et al., 2022 [10]). Rare genotypes (1r, 1s, 1k, 1i) were grouped. Numbers at the top of bar charts indicate the total number of samples for each period. B Proportion of each genotype per French department over the 2011–2023 period. Genotyping data includes current study and those from Rivas et al. [10]. Pie charts denote genotype proportions per department and sizes are proportional to the number of samples. Black boxes show the location of the three focused regions: Bretagne, Normandie and Auvergne-Rhône-Alpes.
