5,000 people event did not cause higher rates of COVID transmission among visitors

Event attendees were required to test negative for COVID and wear masks throughout the event, but no social distancing was required.

Six people tested positive for COVID within 14 days of attending the concert, but the infection rate among attendees was half that of people of the same age who became infected in Barcelona during this period. 

Moreover, four of these people had been infected elsewhere, leading them to conclude that the concert was not the cause of transmission.

All this gives us great hope that concerts, club parties and festivals will return very soon, not only in Spain, but all over the world.
