SIOUX FALLS, S.D. – A study by a California research group estimates that the Sturgis motorbike rally in South Dakota led to greater than 260,000 coronavirus circumstances within the month following the occasion.
Researchers from the Middle for Well being Economics and Coverage Research at San Diego State College printed their findings Saturday in a 63-page report.
The estimate is dramatically greater than the variety of circumstances tied to the rally reported by each the South Dakota well being division and the Related Press.
South Dakota Gov. Kristi Noem on Tuesday stated the research was “fiction,” and she or he criticized journalists who reported on it.
The objective of the research was to estimate the impacts of a single “super-spreader” occasion on the unfold of COVID-19. The identical group has carried out related research on circumstances ensuing from occasions just like the nationwide Black Lives Matter rallies and the June political rally for President Donald Trump in Tulsa, Oklahoma.
Utilizing cellphone knowledge as a part of their evaluation, the researchers recognized areas that noticed plenty of rallygoers and tracked circumstances earlier than and after the occasion.

State epidemiologist: ‘The outcomes don’t align with what we all know’
Noem on Tuesday got here to the protection of rally attendees whereas dealing harsh criticism to the research.
“Underneath the guise of educational analysis, this report is nothing in need of an assault on those that exercised their private freedom to attend Sturgis,” Noem stated within the assertion. “Predictably, some within the media breathlessly report on this non-peer reviewed mannequin, constructed on extremely defective assumptions that don’t mirror the precise information and knowledge right here in South Dakota.”
Noem’s criticism comes hours after related scrutiny from the state’s prime well being officers.
The variety of circumstances estimated within the research differs considerably from the variety of circumstances tied to the rally reported by the South Dakota Division of Well being. As of Tuesday, the state reported 124 circumstances amongst South Dakota residents who bought sick after attending the rally.
The Related Press as of final week recognized 290 circumstances from 12 states tied to the rally.
“The outcomes don’t align with what we all know for the impacts of the rally,” state epidemiologist Josh Clayton stated Tuesday.
That discrepancy is as a result of the state is figuring out particular circumstances via contact tracing. The research takes a special method.
As a substitute of contact tracing and attempting to determine particular individuals who had the illness and handed it on to others, the San Diego researchers regarded on the areas that despatched the most individuals to the rally and the way case tendencies modified after the occasion.
“We’re by no means going to have the ability to contact hint each single particular person from Sturgis,” Friedson stated. “So if we would like a good-faith estimate utilizing, in the mean time, the accepted statistical strategies … that is the very best quantity we’ll get for my part.”
South Dakota Secretary of Well being Kim Malsam-Rysdon disagreed with the methodology of the research Tuesday, questioning the hyperlink between cellphone knowledge and circumstances. She and Clayton additionally famous that the analysis paper isn’t peer-reviewed at this level.
The general public well being value estimate comes largely from a separate research printed final month by two economists. This research discovered nonfatal COVID-19 circumstances value a weighted common of $46,000 per case. Utilizing that quantity – and assuming all rally circumstances had been nonfatal – the San Diego researchers estimated a public well being value of $12.2 billion.

“This is sufficient to have paid every of the estimated 462,182 rally attendees $26,553.64 to not attend,” the paper learn.
Malsam-Rysdon stated she hasn’t seen the analysis behind that value estimate, however she cautioned in opposition to taking it at face worth.
“I might simply warning you about placing an excessive amount of inventory into fashions … that may’t be verified by different factual numbers,” Malsam-Rysdon stated in reference to the research. “I believe that’s the case with that individual white paper.”
Earlier research on the Tulsa and Black Lives Matter rallies did not discover a subsequent uptick in circumstances, Friedson stated, and that is largely as a result of he and his co-authors discovered the brand new circumstances had been offset by extra individuals in these areas staying dwelling throughout these occasions.
What’s distinctive about Sturgis, although, is its small inhabitants. Even when all people on the town stayed dwelling throughout the rally, it would not be sufficient to offset the lots of of 1000’s of attendees, Friedson stated.
