Good news for all those involved in culture, in particular those in music.
The results - eagerly awaited - of the Indochina test concert, organized at the Accor Arena in Paris on May 29, 2021, "demonstrate the absence of an increased risk of infection by SARS-CoV-2 in the participants", indicates the Public Assistance - Hospitals of Paris (AP-HP) this Thursday.
The concert, organized in a scientific setting, brought together nearly 4,000 participants.
All were negative just before D-Day and they had to wear a surgical mask during the 4 hours spent in the room, with an optimized ventilation system.
Instructions were given to respect good hand hygiene, while the bar / restaurant area and smoking areas were closed.

Indochina test concert: "I feel alive again"
These fans from Indochina and Etienne de Crécy had to perform a PCR saliva self-sample 7 days after the concert and only 8 of them were positive.
It is important to note that 5 of these 8 people were already positive on the day of the concert - all had taken a sample but the result was not known - and had therefore been contaminated before.
In the “control” group of nearly 2,000 participants who did not enter the room but who were subjected to the same protocol, 3 were positive 7 days later.
Good mask wear respected at 91%
The ratios of contaminated on D + 7 within each group are therefore very close, respectively 0.2% and 0.15%.
This "corresponds to the incidence rate in Île-de-France estimated in the two weeks preceding the event", indicates the AP-HP.
As for the good respect of the wearing of the surgical mask during the concert ("defined by an adequate port on the nose and the mouth"), evaluated by an artificial intelligence tool, it was evaluated at 91%.
Participants were young (median age 27), predominantly female (57%), and one in two had received at least one dose of the vaccine.

The AP-HP boasts an experience "including a large number of people" and having to wear surgical masks and not FFP2. The data they communicate are therefore very reassuring. It remains to be seen whether they would be equally so in the context of a rapid spread of the highly contagious Delta variant, which was almost non-existent at the end of May, and with other groups of the population.
