Human identical sequence (HIS) is RNA elements of 24-27nt length in coronavirus genomes shared sequence similarity within human genome ,[ 1] act as NamiRNAs (nuclear activating miRNAs) through NamiRNA-enhancer network activates the host genes related to pathology.[ 2] The first HIS elements identified in SARS-CoV-2 genome, which have five HIS elements, other human coronavirus have one to five.[ 1]
