A trial event in Barcelona with more than a thousand audience was successful. Nobody got infected with the corona virus.
The 1,047 attendees between the ages of 18 and 59 danced, sang and drank for 2.5 hours. They did have to wear a certified mouth mask, but they did not have to keep their distance from each other. The mouth masks were allowed to take off while drinking.
The trial event was organized in collaboration with the Primavera Sound festival, an annual festival in Barcelona, to test whether a concert without mandatory spacing leads to new infections. Rapid tests were carried out at the door. The organizers think the findings could be very useful for organizing events in the future.
