The U.S still stands at about 9 new COVID-19 cases per 100K population per day, unchanged from seven days ago.
Take that with a grain of salt, as an increasing number of states seem to be reporting their new case data at more-or-less random intervals.

Separately, the more-infectious son-of-Omicron strain (BA.2) is now the dominant strain in the U.S. Which is great news, given that this has occured and we still aren’t seeing a European-style uptick in cases.Per the U.S. CDC’s COVID data tracker, BA.2 accounted for about 55% of new cases, for the week ending 3/26/2022.
If there’s any link between BA.2 and the regional patterns of increase and decrease shown on the chart above, it’s not obvious at a glance.

Cases are rising rapidly in the Northeast, which has a high proportion of BA.2. Cases are falling rapidly in the Pacific region, which also has a high proportion of BA.2. Whatever the impact of BA.2 is in the U.S., it doesn’t appear to be a prime driver of new case growth so far.
