Molecular Characterization and Phylogenetic Analysis of Hepatitis E Virus (HEV) Strains from Pigs Farmed in Eight European Countries between 2020 and 2022

Figure 2

Map of the European countries involved in this study. The participant countries are highlighted in gray. The frequency of the detected HEV subtypes is displayed by pie charts. The number of unique sequences from each country is indicated in round brackets; since one nonidentical sequence was retrieved for each farm, it corresponds to the number of farms. In Czech Republic and in Poland, the number of farms was 15 and 21, respectively, and more nonidentical sequences, total reported in round brackets, were detected within each farm.
