I don't think it's a big mystery as lay people might think. We track migratory patterns of animals, we tracked migratory patterns of early humans, I would bet that COVID outbreaks track with traditional migratory patterns of the local and transient populations of modern humans. Some states, even in pandemic, have a lot of movement; others even without a pandemic not so much. Vacationers, workers who live across state lines, business travel. If people wonder why Michigan was a hot spot, I would say look at the movements between UK - Toronto - Detroit - Elsewhere in MI. If people wonder why not the South, what would be the insertion point for the virus or a variant? What would be the event, the travel destination, the business destination that would have people exposed in place A , transporting to place B? If an area doesn't get a lot of "cross-pollination" that would be protective against a virus.I am hoping someone tackles this mystery at some point. I would be interesting to do a deep analysis on the course of the pandemic from state to state to try to understand why it played out the way it did.
Limiting movement, either by an order or voluntarily (some places, simply aren't popular destinations) is more effective than most other mitigations. Wyoming's governor has joked through this that they've been social distancing since the founding of the state (although they forgot to consider the tourists) But for a lot of places it's true. Then you're looking at family gatherings like weddings (which may be outside) or the Halloween - New Years period. Some places may not know how well things are until those big yearly activities happen. We shouldn't be expecting an outbreak in a place people rarely go or rarely leave to immediately follow a dial change because the virus can't respond to it. Maybe the next flight to rural wherever for the virus isn't until somebody's June wedding. Kinda like how Disney opened WDW in Oct and attendance was low, but despite the big change in status (closed -> open) it took the event, Thanksgiving, to trigger the human migration. If the virus isn't in a location, and there's not a lot of opportunity to move into a location, nothing is going to happen. It's what happens when someone shows up with the virus, especially if there is a reason for a lot of people to gather (work, church, event, etc), then you see the effects.
