This includes highly sensitive polymerase chain reaction, or PCR, tests, which evaluate the presence of viral RNA in a sample, along with rapid tests that check for viral proteins, or antigens. Prior to the latest rise in cases, South Africa hadrelatively little coronavirus transmission, also making it difficult to say whether omicron can necessarily outcompete delta, either because of increased transmissibility or immune evasion.

So far, it appears that the omicron variant can be detected with existing COVID-19 diagnostics. Even if boosted antibodies have some reduction in efficacy against omicron, the substantially higher antibodies levels generated after the boost are expected to perhaps offset slightly lower neutralization capacity. But, he acknowledged, whether that will be true isnt yet known. At the same time, preliminary data from the country point to an increase in the number of hospitalizations. Omicron virus is a variant of the new coronavirus, which is more transmissible and concealed. The WHO gave the variant its Greek alphabet name on Nov. 26 and labeled it a variant of concern, meaning it could be associated with an increase in transmissibility or virulence, or a decrease in effectiveness of vaccines. Rapid antigen tests show a positive result when the viral load is higher. Not quite a month later, on Dec. 1, the U.S. had its first confirmed case in California, in a person who had returned from South Africa on Nov. 22, and several more cases followed.

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.
