A
university in Germany held a series of crowded pop concerts to find out how
attendees could spread the coronavirus and whether large events can be safely
resumed. Some 1,500 volunteers attended the first of the indoor concerts of
German singer Tim Bendzko in the city of Leipzig. The well-known singer agreed
to give three performances, allowing scientists to try out different
social-distancing scenarios for each concert. Volunteers were equipped with
contact tracers to record their movement and track the path of the aerosols
they emitted. Fluorescent disinfectants were used to show the scientists which
surfaces people touched the most. The researchers from the University Medical
Center in Halle expect the results of their study in four to six weeks. Most events
with big crowds have been put on hold around the world due to the coronavirus
pandemic. In Germany, large gatherings are banned until at least November.
