South Dakota is rapidly approaching population immunity. While South Dakota has seen an influx of people under 30 over the past 10 years, they still have a huge number of elderly in that state. No amount of mask wearing and quarantining prevented COVID from getting in to nursing homes. COVID is hitting that population hard. They have roughly 80,000 confirmed test positive cases but have only been testing symptomatic cases. Recent community testing suggests that like Arizona, there have been 4 times that many cases in their state. Similar to Nebraska the number of cases and the inability to reach people by phone has led to them pretty much abandoning contact tracing.
So out of likely nearly half the state getting COVID, the death rate is still under .3%. You can keep posting all of the tweets and graphs you like. South Dakotans won't care. They understand life and death. Their case and death spike mirrors pretty much exactly the onset of cold weather. Nothing surprising. Minnesota is seeing a similar surge.
