Other ancient strains are marked in blue and modern HBV are shown in black. Numbers at each node are bootstrap support over 500 replications. The tree includes 130 strains (109 modern and 21 ancient). Country codes can be found in the Additional file 1: Table S6. Dates are provided for ancient strainsBack to article page
