The epidemic control command center (CECC) recently spoke about Sars-CoV-2 mutations. According to the CECC, the virus has known four strains of mutated viruses since the start of the epidemic. The first variant was identified as early as February-March. Then, a variant of SARS-CoV-2 in mink in Denmark was spotted in October-November and finally, two other variants were first identified in England and South Africa at the end of 2020.
Luo Yi-jun (羅一鈞), one of the CECC officials, said the virus has undergone four main mutations in one year. Of the four mutated virus strains, the one found in mink in Denmark has not caused a large-scale epidemic in humans. In contrast, the variants identified in England and Africa seem to have a dominance in the capacity for contagion. Consequently, these two strains could replace in the long term that which appeared last February-March to become the next major epidemic strains.
Luo Yi-jun indicates that the CECC closely follows any mutation of the virus as it may accelerate when the vaccines arrive.
