Make the vortices glow: Using tracer particles, a light projection, and high-speed cameras, airflow and particle dispersion are measured indoors at the Hermann Rietschel Institute. Fig. 1: Comparison of the risk factor xr from the simplified risk model for various everyday situations. The durations of stay vary here – a full work or school day is assumed, while a visit to the cinema or restaurant is correspondingly shorter. The reference value is xr = 1 for a half-hour stay in a supermarket with a mask. The value of xr is independent of the respective virus variant. Fig. 2: How many additional people can an infected person infect on average in a specific situation? This is indicated by the Fig. 3: Predicted infection risk for an employee in a large office with ten healthy individuals and one infectious person, plotted over a full workday. The curves correspond to the different measures (combinations) listed on the right. The term Fig. 4: Diagram for determining the infection risk when an infected person is present and statistically averaged infectivity. In the example (red arrows), for moderate ventilation and an average effectiveness of worn FFP2 masks during a six-hour stay, the point is located at the borderline between a low and a medium risk of more than one additional person becoming infected. This applies regardless of a specific number of people and for all typical room sizes.
