The trend numbers for this week will be perturbed by the Memorial Day holiday. So you don’t want to over-analyze this most recent development.
That said, nominally, the U.S. now stands at 29 new COVID-19 cases per 100K population per day. That’s down from 33 just before the holiday, and that’s down 7 percent over the past seven days.
Some chunk of that is due to clear under-reporting in California, so I would expect to see a bit of a rebound. That said, it does appear that outside of the Mountain region, new case counts are flat-to-declining in most parts of the country. It this isn’t the peak of the Omicron-II wave, it’s close.
Data source for this and other graphs of new case counts: Calculated from The New York Times. (2021). Coronavirus (Covid-19) Data in the United States. Retrieved 5/25/2022, from https://github.com/nytimes/covid-19-data.” The NY Times U.S. tracking page may be found at https://www.nytimes.com/interactive/2020/us/coronavirus-us-cases.html
Separately, BA.2.12.1 (Omicron-II) now accounts for about 60% of new U.S. cases. I guess we may now call it a variant of unconcern.
