Berlin study says opera is R-safe at 30% capacitymain
The Technical University of Berlin has issued a study of relative risks of Covid transmission in public places.
It says the lowest risk of infection is in opera houses and theatres that are no more than 30 percent full.
For visits lasting less than two hours, the R value – the Covid transmission rate – is just 0.5. Anything under R=1 does not significantly increase the spread of the disease.
At 40 percent full, the R value rises to 0.6.
In both instances, the risk is lower than an hour-long masked trip to a supermarket.
