DENV-2 phylogenetic tree based on partial M and E gene nucleotide sequences depicting the relationship between the virus acquired by the patient and that used in laboratory experiments (highlighted).

<p>These are compared with other recent DENV-2 isolates such as Townsville 1993 that were imported or resulted in outbreaks in Queensland. Also shown are the genotypes of DENV-2 and representative strains from each grouping.
