Fig. 2From: Circulation of genotypes of dengue virus serotype 2 in Guangzhou over a period of 20 yearsMaximum clade credibility tree of envelope gene nucleotide sequences collected in Guangzhou and from GenBank. Guangzhou sequences, n = 80; GenBank sequences (triangle), n = 53. Posterior probabilities higher than 0.80 are shown at each node. tMRCA = time to the most recent common ancestorBack to article page
