reported its first four cases and one death from COVID-19 on March 10, 2020. On June 15, 2021, South Dakota public health authorities reported 25 new cases of COVID-19, bringing the state's cumulative total to 124,377 cases. The state's COVID-19 death toll is 2,026, with no new deaths reported over the previous 24 hours. The state ranks 9th in deaths per capita among U.S. states (with New York City counted separately), and 3rd in cases per-capita, behind only North Dakota and Rhode Island (14,042 cases per 100,000). The state did not utilize mitigation strategies such as

to have over 3,000 confirmed cases alone by May 11. In August 2020, a major spike in cases was induced by several superspreader events, including the Sturgis Motorcycle Rally (which has officially been tied to at least 290 cases in South Dakota and other states), concerts, and other forms of community transmission. The state peaked in new cases by mid-November 2020; by December, the average rate of new cases in South Dakota had begun to decline. But as of June 2021 South Dakota still has one of the highest rates of COVID-19 hospitalization and death among all U.S. states. As of June 15, 2021, South Dakota has administered 674,054 COVID-19 vaccine doses, providing 55.92% of the state's population with at least one dose of vaccine.

2020 Sturgis Motorcycle Rally and subsequent spike

The Sturgis Motorcycle Rally was held as scheduled from August 7–16, with an estimated 250,000 expected to attend. Although the rally itself was classified by infectious disease professor Carlos del Rio as being of a relatively lower risk due to it being an outdoor event, concerns were raised that attendees would engage in indoor gatherings at bars and restaurants, and that travelers could potentially export COVID-19 cases back to their home states. Mayor of Sturgis Mark Carstensen questioned why the event still went on, admitting that "we cannot stop people from coming." Attendees were encouraged, but not required, to wear a mask. A week after the rally, three days of mass testing were scheduled in Sturgis for local residents. Footage of a concert at Buffalo Chip Campground as part of the festivities showed wide defiance of mask-wearing and social distancing, and

lead singer Steve Harwell telling the audience to "fuck that COVID shit". Public health notices were issued regarding possible exposures at a bar and a tattoo parlor in Sturgis, and a restaurant in Hill City, recommending that visitors monitor for symptoms. By August 26, the number of cases attributed to the rally had reached 70, including 35 cases in Minnesota, 17 in North Dakota, and seven cases in the Nebraska Panhandle. By September 2, the number had increased to 260, and Minnesota reported the first known COVID-19 death among an attendee. The Sturgis Rally and other public events, including concerts at the Sioux Empire Fair, the return to school, and exposures at local businesses, resulted in a surge of new COVID-19 cases in South Dakota. A single-day record of 623 new cases were reported on August 27. On August 30, it was reported that there had been over 2,000 new cases over the past seven days. The next day, Governor Noem downplayed the surge, arguing that "none of this was a surprise", hospitalizations were low in comparison to models, and deaths had trended downward. She also claimed that most of the new cases were among younger residents with a higher chance of recovery, despite cases in people over 70 having increased since the 27th. In September, a non-

(which, by then, had projected 124 in-state cases tied to Sturgis, and 290 across multiple states), and noted that the study was not peer-reviewed. Noem also criticized media outlets for reporting on the study, describing it as a "fiction" based on "incredibly faulty assumptions that do not reflect the actual facts and data here in South Dakota."


Continued surge

From August 16 to September 26, 2020, the seven-day moving average quadrupled from an average of 95.6 cases per-day to 384 cases per-day. On September 16, a single-day record of eight new deaths was reported. By September 23, the state's number of new, active, and hospitalized cases reached new peaks. Along with North Dakota, South Dakota saw the largest per-capita increases in new cases nationwide. On October 1, the state set a single-day record for new deaths, with 13. On October 7, the South Dakota Department of Health (SDDoH) began to identify test positives on antigen tests (which are faster, but less-accurate than PCR tests) in its statistics as "probable" cases. For health care and contact tracing purposes, they are handled the same as those that are confirmed via PCR test. If a probable case is tested via PCR as a follow-up by a clinician, they will be reclassified as a "confirmed" case. However, probable cases might not necessarily be retested. On October 13, Noem attributed the present spike in cases as "expected" due to increased testing, despite a case positivity rate of over 10%. On October 15, the state set a single-day record for new cases, at 876, surpassing previous peaks experienced throughout the month. Cases continued to rapidly increase into November; on November 5, the state surpassed 51,000 cases, with the South Dakota Department of Health (SDDoH) reporting that the state's test positivity percentage had increased to nearly 17%, and its 14-day rolling average was at 19.5%. Test positivity increased to nearly 24% by November 10, with the SDDoH reporting a rolling average of 19.9%. By mid-November, the state's 7-day rolling average per-capita peaked at 165 cases per-100,000. On December 1, the number of active cases in South Dakota fell to its lowest total since early-November, after the state reported a single-day record of 3,542 newly-inactive cases. During the first week of December 2020, South Dakota had the highest mortality rate per-capita among all U.S. states.


Declines

By December 7, the state's seven-day average had begun to decline, with South Dakota ranking third behind Rhode Island and Minnesota in new cases per-capita nationwide. On December 21, Avera Health reported that South Dakota had the highest mortality rate of all U.S. states over the past week, second-highest test positivity, and was 14th in new hospitalizations. On February 22, 2021, the state recorded its fewest new daily cases since July 2020. It has been suggested that personal impacts of the pandemic on residents had led to increased use of masks in South Dakota. Both of the Dakotas had seen noticeable declines in the rate of new cases since December.

declared a state of emergency. Schools were closed beginning March 16. An executive order was issued to encourage social distancing, remote work, and following the CDC guideline of capping enclosed spaces to 10 people at a time. On April 6, Noem ordered vulnerable residents of Lincoln and Minnehaha counties who are 65 years of age or older or have a chronic condition to stay home until further notice. The order was lifted May 11. In contrast to the majority of states (but in line with other rural, Republican-led states such as

as a treatment for COVID-19 symptoms. In late-April 2020, Noem unveiled a "Back to Normal plan", which contains guidance for migrating from the previous recommendations in areas where the rate of new cases had lessened. In late July, Noem ruled out a state mandate on the wearing of face masks in public spaces. Noem disputed studies that had determined face masks to be an effective means of reducing spread of viral particles, arguing that the research was "very mixed" and that "science has not proven what's effective and what isn't and what type of mask. We have to stay objective when we look at it". Noem claimed that studies recommending the use of masks did not use "reliable data sets", and that asymptomatic spread was rare. Noem declined to participate in a federal scheme providing enhanced unemployment benefits, citing a low level of unemployment in the state. In late-August, Noem stated that she would not change her guidance on masks, despite an intensifying surge in new cases. On September 8, despite the continued surge, Noem announced plans to spend $5 million of relief money on an advertising campaign for state tourism. This included an $819,000 buy on

on October 5, Noem stated that a "very prominent national reporter" had praised her for " tandingagainst" lockdowns and proving they were "useless". On October 7, Trump posted a clip of the session on Twitter captioned "Great job South Dakota!"; Noem replied, thanking Trump for giving her government "the flexibility to respect Freedom and personal responsibility", and arguing that they made decisions "based on science, facts, and data". This praise came despite South Dakota having recently set new records for active cases and hospitalizations. On December 7, 2020, Noem published an op-ed in ''

"still has had the most deaths in the country per capita", and that "over the last two weeks of November, its hospitalizations increased by 34 percent, a six-month high". Aaron Blake of ''The Washington Post'' questioned the validity of some of the statistics Noem quoted, noting that South Dakota's mortality rate per-capita on the specified date was "more than twice" that of Illinois, and that Illinois's seven-day average per-capita at the time of writing (79 per-100,000) was lower than South Dakota's peak (165). In regards to New Jersey, Blake noted that the state had the highest mortality rate per-capita overall, but that the majority of these deaths took place in the early stage of the pandemic prior to the mask mandate. In addition, he pointed out that while New Jersey did have a recent spike in hospitalizations, South Dakota had multiple two-week spikes in hospitalizations over the past few months that were higher than 34%, and presently had the second-highest number of hospitalizations per-capita nationwide, 58 (behind only

Local responses

Noem has faced criticism from residents, as well as other city and county leaders, for her lack of state-wide actions to control local spread of COVID-19. The resistance forced municipalities to implement their own ordinances to enforce

, including Sioux Falls—which enacted a "no lingering" ordinance on March 26 to restrict all non-essential businesses to only serving a maximum of 10 customers at a time. Mayor of Sioux Falls Paul TenHaken introduced a proposal for a municipal stay-at-home order on April 14, but it was rejected by city council. On May 8, the "no lingering" ordinance was eased ("no mingling") to allow restaurants to expand to capacity (subject to six-foot social distancing between patrons), and fitness, entertainment, and recreation facilities to expand to half of their licensed capacity, or 10, whichever is greater. On May 19, TenHaken tabled a proposal to sunset the ordinance, citing a slowing in new cases in the city since the new ordinance was implemented. City Health Director Jill Franken also reported that the number of hospitalizations in the area was lower than projected. On May 26, Sioux Falls City Council voted in favor, with the ordinance officially repealed on May 29. Medical responses to the pandemic have largely been coordinated by South Dakota's Avera Health, Monument Health, and Sanford Health systems, including testing, vaccination, and public awareness. On September 8, the city of Brookings became the first in the state to mandate the wearing of face masks in public spaces. The mandate has been credited with lowering the rate of new cases in Brookings County; by late-November, it had the lowest number of cases per-100,000 among South Dakota's 10 most populous counties, at 74.
