The U.S. is reporting an average of 760,000 new cases per day, according to federal data.
Although case levels remain high, there's growing evidence to suggest the omicron surge is receding in the parts of the country first struck by the variant.

Wisconsin now leads the nation in new cases per capita, followed by Rhode Island, Utah and South Carolina.
