Nature reveals where did the new crown Omicron variant come from?
Time of Update: 2022-03-09
Prior to this report, scientists were working on three theories: (1) Although researchers have sequenced millions of SARS-CoV-2 genomes, they may have simply missed a series of events that ultimately lead to Omicron Mutation; (2) Alternatively, the mutation may evolve a mutation in a person as part of a long-term infection; (3) it may arise in other animal hosts, such as mice or rats .
