The specimen for the first confirmed case in South Africa had been collected on Nov. 9. At the same time, other mutations are thought to, to the Centers for Disease Control and Prevention, suggests omicron is likely to have increased transmission compared to the original SARS-CoV-2 virus, but it is difficult to infer if it is more transmissible than Delta., of COVID-19 cases in South Africa, which appears to be, due to omicron, also suggests the variant could be more contagious.

Some doctors assert the safest course of action is to remain in isolation until you test negative. Other treatments, such as those that target the immune response, including steroids, Gilead, the maker of the antiviral drug remdesivir, which works by inhibiting viral replication via the viral polymerase, said in a Dec. 1. that analysis of omicron sequences does not show any new mutations in the polymerase, so it expects the drug to be active against the variant. Its possible, for example, that the uptick in cases happened by chance and was sparked by asuperspreading eventin a person or people who happened to be infected with omicron, rather than because of a change in the viruss intrinsic transmissibility.
