Spatial distribution of analyzed RHD2 outbreaks in French hare and rabbit populations (January 2013–February 2015). Data are pooled by department (administrative area) and the color indicates the species involved in the analyzed outbreaks. Black: Lepus europaeus; light grey: Oryctolagus cuniculus; dark grey: the two leporid species. White: no data. The numbers refer to RHDV2 strains characterized in hares and the letters to RHDV2 strains characterized in rabbits. The order of the numbers and the letters corresponds to the order in which the VP60 sequences are positioned in the phylogenetic tree from top to bottom (Figure 2). *Recombinant RHDV-G1/RHDV2 strains, †unsuccessful 1U/1L PCR amplification.
