The figure exhibits the empirical improvement of the cumulative variety of COVID-19 circumstances in Jena and the estimated development in numerous synthetic control groups over time.
This drop is best, by more than 90%, for the age group 60 y and above. Our results are robust to different sensitivity checks, amongst that are placebo-in-house and placebo-in-time analyses.

When the quantity of exhaled virus was reduced to 105 PFU or 104 PFU, infectious viruses were not detected, even within the samples from the unmasked receiver (Fig. 2H and I).
