NEW YORK (AP) — Omicron has raced forward of different variants and is now the dominant model of the coronavirus within the U.S., accounting for 73% of latest infections final week, federal well being officers mentioned Monday.
The Facilities for Illness Management and Prevention numbers confirmed almost a six-fold enhance in omicron’s share of infections in just one week.
In a lot of the nation, omicron’s prevalence is even larger. It’s accountable for an estimated 90% of latest infections within the New York space, the Southeast, the commercial Midwest and the Pacific Northwest.

For the reason that finish of June, the delta variant has been the principle model inflicting U.S. infections. As just lately as the top of November, greater than 99.5% of coronaviruses had been delta, based on CDC information.

He predicted unfold over the vacations, together with breakthrough infections among the many vaccinated and critical problems among the many unvaccinated that might stress hospitals already burdened by delta.
CDC’s estimates are primarily based on hundreds of coronavirus specimens collected every week via college and business laboratories and state and native well being departments. Scientists analyze their genetic sequences to find out which variations of the COVID-19 viruses are most considerable.
Within the week that ended Dec. 11, omicron’s share of latest infections within the U.S. elevated to 2.9% from 0.4% the week earlier than, the CDC beforehand reported.
