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

Abstract

Zika virus is the new focused virus in tropical medicine. The Zika virus infection can result in acute hemorrhagic febrile illness and the infection can also result in birth defect [1], [2]. The disease has been known for several decades but the big outbreaks have just been noted for a few years and the infection becomes the present global problem. There are many ongoing researches on this new infection. An interesting aspect is on the genetic epidemiology of this disease [3]. Success in isolation of virus could be seen in several recent outbreaks and the genetic contents analyses of the isolates were also done. “Passage history of the virus” can be seen from analysis of such data [4]. 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 [4]. 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.
