In our choir, we are discussing measures to slow the spread of the novel Coronavirus in our community. However, I lack understanding about how the virus spreads in a closed room. The German Public Health authority recommends "Social distancing" of 1-2m.
However, in a choir, many people are singing all the time on the same location. Singing also produce respiratory droplets [src1] and I don't know how long those droplets stay infective.
- [src1] states that droplets dry out within 2m. Are Coronaviruses only infective while suspended in these droplets?
- Given the long exposition of the people to each other and the long duration of singing, are the recommendations of Social Distancing applicable to choirs?
