The U.S. once again broke COVID-19 records this week, reporting about 5.5 million new cases in total. Last winter, the highest number of cases reported in a single week was about 1.7 million; this past week, the country reported over one million cases just on Monday (though that number included backlogs from the prior weekend).

Omicron continues to drive record cases across the U.S., as we move from tense holiday gatherings to extremely fractured schools and workplaces. This week, the CDC reported 4.1 million new cases—almost double last week’s number, and about 2.5 times the case peak reported during last winter’s surge.

It’s difficult to interpret COVID-19 data in the wake of any major holiday, as public health officials and testing sites alike take well-deserved time off. That said, we have enough data to say that cases are rising incredibly fast across the U.S. The country reported over 300,000 new cases a day this week—the highest seven-day average of the entire pandemic so far. Over 500,000 new cases were reported on Friday alone.

Last week, the Omicron surge had clearly arrived; this week, it’s picking up steam. Nationwide, the U.S. reported well over one million new cases this week—more than a 40% increase from last week. 244,000 cases were reported on Thursday alone, and the daily new case average is now higher than at any point during the Delta surge.

The Omicron surge has arrived in the U.S. While national COVID-19 cases are not significantly up from last week to this week, last week’s bump in the numbers from delayed Thanksgiving reporting has been replaced with a true increase, thanks to the combined pressures of both Delta and Omicron.

Remember how, last week, I said that the dip in the CDC’s case counts was a vestige of Thanksgiving data delays—and we’d see more cases in the next week? Well, we’re seeing those cases now. Cases have increased by 37% from last week to this week, and they’ve increased by 55% in the last month.

Don’t be fooled by the apparent case decline in the CDC’s numbers: the U.S. is still in the midst of a new surge. The agency reported fewer cases last week due to Thanksgiving holiday delays, but we can expect cases to shoot up next week as delayed cases are added to the data.

As is typically the case on holidays, Thanksgiving has made COVID-19 reporting a bit wonky. Still, cases seem to continue trending up at the national level. The U.S. is now reporting close to 100,000 new cases a day, and holiday travel is likely to push this number up further.

Last week, I wrote that the U.S. was at the start of a winter surge; this week, the surge is beginning to take off. Nationwide, cases are up 16% from last week to this week, and up 24% from two weeks ago. It’s not as sharp of an increase as what we saw during the first Delta surge in the summer, but it’s still concerning.

It may be happening slowly, but the U.S. is clearly at the start of a winter COVID-19 surge. The number of newly reported cases rose this week for the first time since early September, while the number of COVID-19 patients in hospitals has plateaued.
