Lowest risk of infection in concert and opera
A Berlin study shows: People are much less likely to be infected with the coronavirus in enclosed cultural spaces than in supermarkets, gyms or on the train.
The study assesses the risk of infection based on the inhaled dose. This in turn depends on factors such as emission rate, respiratory activity, aerosol concentration and length of stay. In their assessment of the probability of infection, the researchers assumed that there was an infected person in all the enclosed spaces studied. In summary, it is stated that the situational R-value in cultural venues is lower than in classrooms or offices.
Using one example, the study concludes that a visit to the theater is "only half as risky in a venue with 30% occupancy and wearing a mask even when seated as in a supermarket." The illustrative graphic also shows that the risk of infection is lowest indoors in concert halls, theaters, cinemas and museums.
The Neue Zürcher Zeitung presented the study in detail on February 15. A number of examples are discussed in detail.
