South Dakota health officials are dismissing a report from the IZA Institute which claims the Sturgis motorcycle rally served as a covid-19 “Super spreader event. IZa is an economic research institute and think tank located in Bonn Germany, which produced a 63 page paper on the matter and claims over 250,000 reported COVID cases between August 2nd and September 2nd are due to Sturgis. That is 19 percent of the nation’s cases during that time. State Epidemologist Dr. Joshua Clayton says the study is a white paper and is not peer reviewed and that the impacts from the rally do not align with what the authors found.
