Over the last months, we developed an app for the Max Planck Institute for Dynamics and Self-Organization and the University Medical Center in Göttingen which calculates the indoor risk to contract a COVID 19 infection. The researchers, led by Freja Nordsiek, Eberhard Bodenschatz and Gholamhossein Bagheri, developed a detailed model for the spread, settling and inhalation of minuscule droplets containing virus particles and how these droplets change your risk depending on parameters like room size, ventilation or the type of mask you are wearing.
The app is now published at https://aerosol.ds.mpg.de, so try it out and stay safe!
