The Omicron variant of the novel coronavirus is estimated to have taken over Delta as the most prevalent strain contributing to new COVID-19 infections, accounting for 58.6 percent of all strains actively circulating in the United States as of Dec. 25, the Centers for Disease Control and Prevention (CDC) said, as it drastically revised an earlier projection of new Omicron infections.
CDC officials significantly reduced estimates for the week ending Dec. 18 that had erroneously indicated a nearly six-fold increase in Omicron’s share of infections in only one week. The figures showed that the newly detected variant accounted for roughly 73 percent of new infections nationwide.
Federal officials cited those figures to announce that the Omicron variant had become the dominant source of new infections in the United States.
The agency has now revised down the Omicron proportion of cases for the week ending Dec. 18 to 22.5 percent from 73.2 percent, citing additional data and the rapid spread of the variant that in part caused the discrepancy.
“We had more data come in from that timeframe and there was a reduced proportion of Omicron,” a CDC spokesperson said. “It’s important to note that we’re still seeing a steady increase in the proportion of Omicron.”
The Biden administration didn’t immediately respond to a request for comment by The Epoch Times.
The Delta variant, which had been the dominant strain in the past few months, accounts for 41.1 percent of all U.S. COVID-19 cases as of Dec. 25, the public health agency’s data projections showed.
“Setting aside the question of how the initial estimate was so inaccurate, if CDC’s new estimate of Omicron prevalence is precise, then it suggests that a good portion of the current hospitalizations we’re seeing from COVID may still be driven by Delta infections,” former Food and Drug Administration (FDA) Commissioner Scott Gottlieb said on Tuesday.
The agency said the data includes modeled projections that may differ from weighted estimates generated at later dates.
The Omicron variant was first detected by doctors in Africa less than a month ago, and on Nov. 26, the World Health Organization designated it as a “variant of concern.” The variant has since been reported in around 90 countries.
CDC officials have said they do not yet have estimates of how many hospitalizations or deaths are due to the Omicron variant of the CCP (Chinese Communist Party) virus, which causes the disease COVID-19.
Recent studies have shown that the Omicron variant presents milder symptoms and fewer hospitalizations than earlier strains. Some officials, including White House COVID-19 adviser Dr. Anthony Fauci, have said that because of Omicron’s high degree of transmissibility, it may lead to more hospitalizations in the coming days.
