"The Centers for Disease Control and Prevention has revised down its estimates for US infection by the Omicron variant, stating it accounts for approximately 59% of all Covid cases in the US, not 73% as it previously said... The disparity in estimates, while confirming the rapid spread of Omicron, also speaks to relative lack of precision in detecting a new variant that can only be confirmed by genetic analysis... the numbers come with the caveat that many testing centers were closed over the holiday weekend, and a CDC spokesperson told Politico that the number was likely an 'overestimate' due to a delay in state reporting."
