Genetic diversity of hepatitis viruses in West-African countries from 1996 to 2018

Figure 2 Phylogenetic tree of 53 hepatitis B virus genotype E and A sequences identified in West African Economic and Monetary Union countries including Ghana and Nigeria (indicated ♦). Phylogenetic analysis was performed with the neighbor-joining algorithm based on the Kimura two-parameter distance estimation method. Only bootstrap values of > 80% are shown (1.000 replicates). Reference hepatitis B virus sequences (44) recovered from GenBank are denoted with their accession numbers and genotypes/sub-genotypes are indicated.
