ZIka virus infection in Asia: reappraisal on phylogenetic data of Asian lineage

Zika virus infection becomes the important global problem in the present day. The worldwide distribution of the infection can be seen. The genetic epidemiology study shows that the infection has subgroups of outbreaks. The Asian lineage is an interesting group that can be seen in a wide area. In this short article, the authors reappraises on the phylogenetic data of Asian lineage. The study on period, distance and phylogenetic parameter differences among isolated from several countries in the Asia lineage group is done. Based on the present study, the time and place dimnensional analysis can show that the disease distribution should be mainly induced by the international traveling.
