The CDC significantly reduced its estimate for how prevalent the omicron variant of COVID-19 was in the United States earlier in December, saying on Tuesday that the omicron variant was responsible for 22.5% of all new cases for the week ending December 18 after previously saying the omicron variant was responsible for 73.2% of all new cases for the same week.
For the week ending Dec. 25, the agency says omicron accounted for 58.6% of all new cases.
Jasmine Reed, a spokesperson for the CDC, noted that there was “a wide predictive interval posted in last week’s chart,” and the downward revision was partly due to the “speed at which Omicron was increasing.”
“CDC’s models have a range, and… we’re still seeing steady increase in the proportion of Omicron,” Reed told Fox News Digital. “In some regions in the country, Omicron accounts for ~ 90% or more of cases.”
