Omicron estimated to be 58.6% of coronavirus variants in U.S.- CDC

[December 28, 2021]  (Reuters) - The Omicron variant was estimated to be 58.6% of the coronavirus variants circulating in the United States for the week ending Dec. 25, according to data from the U.S. Centers for Disease Control and Prevention (CDC).

The fast-spreading variant was first detected in southern Africa and Hong Kong in November, with the first known case in the United States identified on Dec. 1 in a fully vaccinated person who had traveled to South Africa.

The Delta variant accounts for 41.1% of all U.S. COVID-19 cases, according to the public health agency's data on Tuesday https://covid.cdc.gov/covid-data-tracker/#variant-proportions.

The agency said the data includes modeled projection that may differ from weighted estimates generated at later dates.
