Soon after the outbreak of the pneumonia in Wuhan, studies ruled out the association of commonly known respiratory pathogens. In the Wuhan Institute of Virology, by the first week of January, 2020, a coronavirus was isolated from the samples of the patients of the initial outbreak of the disease, who were sellers or deliverymen from the seafood market [19]. Five out of seven samples in the initial RT-PCR test with the pan-coronavirus primers showed positive amplification. In order to identify the specific virus, one positive sample (WIV04) was subjected for the metagenomics analysis using next-generation sequencing and finally a genome of 29,891 nucleotides was obtained, which shared 79.6% sequence identity with SARS-CoV BJ01 [19].
