Wear a masks inside your own home if somebody you reside with is sick with symptomsof COVID-19 or has examined optimistic for COVID-19.

Further single-unit treatment analyses are proven in SI Appendix, part D.1. To guarantee a sufficiently long remedy period, we contemplate all areas as treated which introduced face masks on or earlier than 22 April. We estimate average treatment effects in a multiple treatment SCM approach for 1) all of these regions and 2) a subset consisting of larger cities (kreisfreie Städte) solely. In the former case we have a complete of 32 treated models, and in the latter there are eight treated items. The donor pool of control areas is specified such that the minimum time lag within the introduction of face masks between treated and control areas ranges between 5 and thirteen d.

We want to point out that neither the limited pixel decision nor the saturation affect the particle counts presented in Fig. The experimental setup could be very simple to implement, and the required hardware and software program are ubiquitous or easily acquired. However, this simplicity does go together with some limitations that are discussed here, along with routes for possible improvements and future studies. Again, we want to observe that the masks exams performed right here ought to serve only as an illustration.
