Experiment - concert under corona conditions

22 August 2020, Saxony, Leipzig: The German pop singer Tim Bendzko (in front) performs with a band on stage during a large-scale experiment of the University Medical School Halle/Saale in the Arena Leipzig. Around 2200 visitors take part in the experiment entitled "Restart-19", in which the pop singer Tim Bendzko performs at a concert. The scientists want to use sensors and other aids to monitor walking paths and fluorescent disinfectant should make visible which surfaces are often touched. The researchers also hope to track the flight of aerosols - the smallest mixtures of particles that could carry the virus. The aim is to develop a mathematical model with which the risk of a corona outbreak after a major event in a hall can be assessed.
