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. Experts say the study suggests two things: that omicron behaves differently than previous variants of the virus, and that a negative rapid test doesn't necessarily mean a person does not have transmissible levels of the coronavirus.
