World Health Organisation (WHO) has classified COVID-19 as a β CoV of group 2B [23]. Ten genome sequences of COVID-19 obtained from a total of nine patients exhibited 99.98% sequence identity [19]. Another study showed there was 99.8–99.9% nucleotide identity in isolates from five patients and the sequence results revealed the presence of a new beta-CoV strain [5]. The genetic sequence of the COVID-19 showed more than 80% identity to SARS-CoV and 50% to the MERS-CoV [5,19], and both SARS-CoV and MERS-CoV originate in bats [24]. Thus, the evidence from the phylogenetic analysis indicates that the COVID-19 belongs to the genus betacoronavirus, which includes SARS-CoV, that infects humans, bats, and wild animals [25].
