In the end of year 2019, in the city of Wuhan (China), individuals were presented with viral pneumonia caused by microbial agent that was unidentified. The agent causing the diseases was identified as novel coronavirus, which was named provisionally 2019 novel coronavirus (2019-nCoV). 2019 novel coronavirus is amply contradictory from SARS-CoV to be deliberated as a different human-contaminating beta coronavirus. Though the phylogenetic investigation proposes that bats might be the novel virus host, a seafood animal sold market in China might characterize a transitional host expediting the appearance of the virus in human beings. Significantly, structural investigation proposes that 2019-nCoV might be capable to muddle to the angiotensin-converting enzyme 2 receptor in human beings. The imminent adaptation, evolution, and extent of this virus permit imperative research.
