National numbers, June 25

The CDC failed to update its primary COVID-19 metrics this week, so I have no national updates to share about hospital admissions, deaths, or test positivity. The most recent available data from the agency and wastewater surveillance sources suggest that the U.S. is still experiencing a transmission plateau.

Overall, the national COVID-19 picture remains fairly similar to what we’ve seen for the last few weeks. The U.S. is at a plateau of COVID-19 spread; we could see an increase this summer, but limited data make it hard to say for sure.

America’s Omicron subvariant surge continues to be in a plateau this week, with national COVID-19 case rates, hospitalization rates, and wastewater trends remaining fairly level or showing slight declines.

The BA.2/BA.2.12.1 surge continues. According to the CDC, the number of new cases reported nationwide dropped last week, compared to the prior week; but this drop is more likely a result of the Memorial Day holiday than of an actual slowdown in transmission.

Cases have continued to plateau this week, with less than a 5% drop in the daily average. As I’ve said in previous weeks, this is partially due to slowing vaccinations—the White House admitted last week that the U.S. won’t meet Biden’s July 4 goal—and partially due to the Delta variant, which now causes at least 20% of new cases in the country.

The CDC updated its variant prevalence estimates this week, reporting that the Delta variant makes up 10% of U.S. cases as of June 5. This aligns with other estimates I cited last week, and suggests that the variant is spreading here at a truly rapid pace—its prevalence multiplied by four times in two weeks, according to CDC data.

After several weeks of sharp declines, new COVID-19 cases in the U.S. now appear to be in a plateau. There are a few factors likely influencing this shift: the aftermath of a reporting lag over Memorial Day weekend, the slow pace of vaccinations, and the rise of the Delta variant.

Cases continued to fall this week, with a seven-day average now under 20,000 new cases a day. This is basically the lowest number we’ve seen in the U.S. since spring 2020—though it’s important to note that the U.S. was doing minimal testing at that time, so the true case numbers in March 2020 were likely much higher than what was reported.
