We estimate overall effects for these variables together with disaggregated effects by age teams (individuals aged 15 to 34 y, 35 to fifty nine y, and 60+ y).
- Depending on the region we think about, we discover that face masks reduced the number of newly registered SARS‐CoV‐2 infections between 15% and seventy five% over a interval of 20 days after their obligatory introduction.

The visual inspection of the distinction between Jena and its artificial control group factors to the presence of a small anticipation impact. Yet, the gap to the synthetic management significantly widens solely ∼10 to 12 d after the announcement after which grows considerably over time. As this temporal transmission channel seems believable given a median time lag between infection and registration of almost equal size, we take this as first evidence for a face masks impact in the discount of SARS-CoV-2 infections. 1A clearly reveals a progressively widening hole in the cumulative variety of COVID-19 circumstances between Jena and its artificial control group.

We argue that the latter ought to thus be interpreted as a decrease certain for the true remedy results.
Our quasi-experimental control group strategy utilizing SCM reveals that the introduction of face masks on 6 April reduced the variety of newly registered COVID-19 circumstances over the subsequent 20 d by 75% relative to the artificial management group. Comparing the every day growth fee within the synthetic control group with the noticed every day growth fee in Jena, the latter shrinks by around 70% due to the introduction of face masks. The introduction of mandatory face masks and the related sign to the native inhabitants to take the chance of individual-to-person transmissions significantly apparently helped considerably in decreasing the unfold of COVID-19. Looking at average treatment effects for all different regions places this result in some perspective. The discount in the daily progress price of infections amounts to 14% only. By distinction, once we focus on larger cities, we discover a discount in the every day growth rate of infections by roughly forty seven%.
