The Sturgis Motorcycle Rally led to significant spread of the novel coronavirus in the event’s home state of South Dakota and in other parts of the United States, a team of researchers said in a newly released study that is disputed by state officials.
The report from San Diego State University’s Center for Health Economics & Policy Studies used anonymized cellphone location data and virus case counts to analyze the impact of the 460,000-person event that took place last month, believed to be one of the largest events held during the pandemic. Health officials had expressed concerns about the rally, which, the researchers noted, “represents a situation where many of the ‘worst case scenarios’ for superspreading occurred simultaneously.” Those included the event being prolonged over 10 days, attracting a significant out-of-town population and involving attendees clustered together, with few wearing masks.
The consequences were “substantial,” the researchers concluded. By analyzing the parts of the country that had the highest number of Sturgis attendees and changes in coronavirus trends after its conclusion, they estimated 266,796 cases could be linked to the rally. That’s about 19 percent of the number reported nationally between Aug. 2 and Sept. 2, and significantly higher than the number state health officials have linked through contact tracing. Based on a covid-19 case statistically costing about $46,000, the researchers said, that would mean the rally carried a public health price tag of $12.2 billion. Continue reading.
