" U.S. biker rally may have led to 260,000 new COVID-19 cases: study
The bikers generally did not wear masks or practice social distancing, the study said, citing media reports.
Using data from the Centers for Disease Control and Prevention (CDC), the researchers then showed that a month following the rally, cases in the county where Sturgis is located rose by six or seven per 1,000.
U.S. counties that contributed the highest numbers of attendees experienced a rise of 7 to 12.5 percent in the number of cases compared to those that did not contribute inflows.
Researchers said their calculations indicated "a total of 263,708 additional cases in these locations due to the Sturgis Motorcycle Rally".
