It introduced face masks as the first region in Germany while in our posttreatment interval hardly any other public well being measures have been launched or eased. Hence, it supplies the most clear-reduce quasi-experimental setting for learning its results. Second, as described in Method and Data, Jena is a reasonably representative region of Germany when it comes to COVID-19 instances.

All data underlying the outcomes are available as part of the article, and no further supply knowledge are required for interpretation. The working doc was uploaded as a preprint in preprints.org, and improvements incorporating additional evidence had been added. It is also necessary for health authorities to supply clear pointers for the production, use, and sanitization or reuse of face masks, and consider their distribution as shortages allow. Clear and implementable guidelines can help increase compliance, and convey communities closer to the aim of reducing and finally stopping the spread of COVID-19.
