It did, according to a report Friday that looked at cases in neighboring Minnesota.
About one-third of counties ended up having at least one coronavirus case that was tied to August's Sturgis Motorcycle Rally, investigators reported in a study mainly conducted by Minnesota health officials and published by the U.S. Centers for Disease Control and Prevention.
The report showed that 51 of the cases occurred between people who attended the rally, while 35 contracted the virus after making contact with the infected attendees in social settings and at work. Most did not suffer serious illnesses, but four were hospitalized and one died.
The rally has been a source of contention between the governors of Minnesota and South Dakota.
"The motorcycle rally was held in a neighboring state that did not have policies regarding event size and mask use, underscoring the implications of policies within and across jurisdictions", the CDC said. "Furthermore, although these findings did not capture the impact of the motorcycle rally on residents of other states, they demonstrate the rationale for consistent mitigation measures across states".
In August, the rally had no mask mandate, raising concern over a potential case hike following the event.
At the time, health experts feared the Sturgis rally would become a superspreader event, with thousands of people from all over the country attending, and numerous events held indoors.
Noem has not issued any restrictions during the pandemic, instead encouraging residents to "exercise personal responsibility and make smart choices".
