Omicron estimated to account for 98% of new US cases: CDC
Omicron is estimated to account for 98.3% of new cases in the U.S. as of Jan. 8, according to new data released by CDC Tuesday. (These figures are calculated using modeling and may not be exact.)
Delta now accounts for only 1.7% of new cases nationally, forecasters estimate.
In three areas of the country -- the deep South, the Southeast and the New York/New Jersey region -- omicron is estimated to account for more than 99% of new cases.
In early December, omicron was estimated to account for just 0.6% of all new cases.

Feds buy more monoclonal treatment that fights omicron
The U.S. government is buying 600,000 more doses of sotrovimab, the only the monoclonal antibody treatment expected to hold up against omicron, according to the drug makers, GlaxoSmithKline and Vir Biotechnology.
These doses are set to be delivered to the government over the next two months, the drug makers said.
This brings total sotrovimab doses purchased by the federal government to approximately 1 million.
Short supply of sotrovimab has been a growing concern for the White House as omicron spreads.
Until recently the government had not invested in buying bulk stock of sotrovimab, as it has with other monoclonal treatments. The government spent billions buying Regeneron and Eli Lilly's products to ensure there would be enough supply, but both of those may not hold up against omicron.
