COVID cases are up 55% across the U.S.

Where it stands: Nationwide, the average number of new cases per day was up 55% over the past week.

New cases increased in 46 states, and many of those increases are substantial.

Florida is now averaging just under 6,500 new cases per day — by far the most of any state, and a 91% jump from the week before.

New cases more than doubled over the past week in Mississippi — from about 320 per day to about 660 per day. The state has one of the lowest vaccination rates in the country; just 34% of its residents are fully vaccinated.
