The experts at the TU Berlin have other rooms and situations compared.

It turns out that especially in Offices, schools and in private households is this risk of infection especially high.

regular airing, reduced length of stay such as large rooms With few people and also wearing FFP2 masks can greatly reduce the risk of infection.

Database:
**The researchers at the TU Berlin calculate in a classroom with normal occupancy (24 students) with 25m³ of outside air per hour and person. They also assume that wearing a mouth and nose protector reduces the emission of the infected person and also results in a filter performance when the healthy person inhales. In addition, the scenarios are played out using secondary schools, since the data on infection among younger children is still too unclear.
The dimensions of the classroom shown are 8.57 mx 7 mx 3 m.

The researchers did not take the vaccination status into account because their risk model only considers the risk of infection. Background: The authors point out that although vaccination increases personal protection, it does not necessarily protect against omicron infection.
