One pair of key mutations has also been shown in lab tests to allow SARS-CoV-2 viruses to bind more strongly to the ACE2, the human receptor that the virus uses to gain entry into cells.

Gilead, the maker of the antiviral drug remdesivir, which works by inhibiting viral replication via the viral polymerase, said in a Dec. 1statementthat analysis of omicron sequences does not show any new mutations in the polymerase, so it expects the drug to be active against the variant. a negative result with a test done in the morning can turn out to be positive in the afternoon or evening.
