At this point, I'm not even looking at detected case numbers. There are so many undetected cases with Omicron, not really much point. Hospitalization stats are decent for most states, with a few exceptions. I only look at the NY Times or
CovidActNow because it's easier and they use consistent data sources. With CovidActNow I can choose which states to compare. Also can easily see All Time, 180 days, or 60 days. With Omicron, looking at 60 days it's pretty easy to get a sense of the regional differences. I don't look at large states like NY, FL, TX, or CA very much because there is too much variation within the state. Large populations mask what's really going on. Just as considering the vax rate for all 330 million Americans doesn't really mean much when the range by county is probably from 30% to almost 90%.
New England is a mix. CT and MA seem to be somewhat different than VT, NH, ME. Probably because CT and MA have more large urban areas. VT, NH, ME look like there was a Delta surge after Thanksgiving, followed by a more recent Omicron surge.
Looking at only the past 60 days, pretty clear that the southeast and Rocky Mountains haven't reached an Omicron peak yet. Note that during the winter of 2019-20, Colorado was one of the first states to have imported cases of COVID-19. I read about more than one international traveler who did ski vacations there in Feb 2020. They tested positive soon after leaving the USA.
