Viruses spread primarily via droplets. How the smallest of these droplets spread when singing, speaking or breathing in closed, unventilated rooms is being analyzed by researchers at TU Bergakademie Freiberg together with the University Medical Center Leipzig and the St. Georg Hospital.

In the research project "Virus particle flow - musicians' medicine and patient rooms" they are currently investigating the spread of viruses, especially when singing in closed rooms and when caring for ventilated patients in patient rooms. The main focus is on so-called aerosols. These are very small droplets that, in contrast to larger drops, float in the air for a longer period of time and thus possibly represent a further form of propagation.

To this end, scientists at the Institute of Mechanics and Fluid Dynamics at TU Bergakademie Freiberg are using computer simulations to investigate the exhalation and dispersion of aerosols in the ambient air. The results show how aerosols are transported from person to person when singing, speaking or breathing and should make it possible to further optimise existing hygiene measures and thus at the same time make a contribution to the fight against the corona virus.

In addition to TU Bergakademie Freiberg, the University Medical Center Leipzig and the St. Georg Hospital, the Central German Institute of Occupational Medicine, the Leipzig Opera House, the Leipzig University of Music and Theater and the Leipzig Gewandhaus are involved in the preparation and implementation of the project. The research project aims to develop recommendations for action in the field of musical culture and clinical patient care.
