COVID-19: Distancing and Masks are not Enough

Now a fluid dynamics team has developed new models: Masks and distancing are good, but not enough. 1/2 images Droplets with a viral load [Translate to English:] Tröpfchen haben begrenzte Reichweite, Aeorsole können aber größere Distanzen überbrücken [Translate to English:] Tröpfchen haben begrenzte Reichweite, Aeorsole können aber größere Distanzen überbrücken Wear a mask, keep your distance, avoid crowds - these are the common recommendations to contain the COVID-19 epidemic. However, the scientific foundations on which these recommendations are based are decades old and no longer reflect the current state of knowledge. To change this, several research groups from the field of fluid dynamics have now joined forces and developed a new, improved model of the propagation of infectious droplets. It has been shown that it makes sense to wear masks and maintain distances, but that this should not lull you into a false sense of security. Even with a mask, infectious droplets can be transmitted over several meters and remain in the air longer than previously thought.
