A document was published by the Freiburg University of Music on April 25, 2020 entitled Risk Assessment Regarding Corona-Infections in Music Making . A section regarding wind instruments is quoted below.
To the best of our knowledge, there are no measurements of the viral load in the blowing air of wind instruments at present. It is known, however, that wind instrument playing requires an intensive exchange of air in the lungs and respiratory tract with sometimes high air pressures. To what extent the viral load is reduced by the airway in the instrument is unclear. It is to be assumed that the release of the breathing air into the environment during playing can lead to virus-containing aerosols. In addition, playing wind instruments causes condensation of the exhaled air in the instrument, which is to be regarded as another potentially virus-spreading material.
Then, a study regarding aerosol spread by The Bamberg Symphony published today shows preliminary results that look promising for trombone, bassoon, clarinet, oboe, and horn players. Excerpts from this report are below.
