Coronaviruses are a large family of viruses that are known to cause illness ranging from the common cold to more severe diseases. Aa an enveloped RNA virus, Cov is ubiquitous in humans, other mammals, and birds, which can cause respiratory, digestive, liver and nervous system disorders [5,6]. To date, six CoVs have been known to cause human infection [7]. Among them, two zoonotic viruses, SARS-CoV and MERS-CoV, were responsible for serious outbreaks: in China in 2002–2003 [8, 9] and in the Middle East in 2012 [10], respectively. A novel coronavirus was identified in late 2019 in Wuhan, China. This is a new coronavirus that has not been previously identified in humans. On 11 February, The International Committee on Taxonomy of Viruses (ICTV) announced that the official classification of the new coronavirus (2019-nCoV) is called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The World Health Organization (WHO) announced on the same day that the official name of the disease caused by the virus is Corona Virus Disease-19 (COVID-19).
