Evolutionary study of COVID-19, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as an emerging coronavirus: Phylogenetic analysis and literature review.

Abstract

Since emerging coronaviruses have always become a human health concern globally especially severe acute respiratory syndrome coronavirus 2 (SARS‐CoV) and Middle East respiratory syndrome coronavirus and a novel coronavirus was introduced in Wuhan, China, in December 2019 (called SARS‐CoV‐2), many researchers focused on its epidemics, virological and clinical features. SARS‐CoV‐2 is classified as Betacoronaviruses genus and Sarbecovirus subgenus (lineage B). The virus shows a great similarity with SARS‐CoV and bat SARS‐like coronaviruses. In this study, we evaluate SARS‐CoV‐2 virus phylogeny and evolution by using current virus and related sequences.
