Abstract: The present disclosure relates to a coronavirus-specific double-stranded oligonucleotide and a use thereof. The present disclosure induces RNA interference specific to a coronavirus, particularly, to SARS-CoV, SARS-CoV-2, and a mutant thereof so as to effectively inhibit viral infection and proliferation, and is nearly unaffected by viral variants since a conserved sequence is mainly targeted. Therefore, the double-stranded oligonucleotide of the present disclosure may be effectively used in proliferation inhibition, infection prevention, and disease treatment of the coronavirus, and particularly, may be effectively used as an agent for preventing and treating COVID-19, which is the cause of the current pandemic.
