Face masks highly effective against Covid-19, new evidence suggests
Three separate studies find routine wearing of face masks can curb spread of coronavirus
The first study examined the city of Jena in Germany, which made it compulsory for residents to wear face masks in public places, such as on public transport and while shopping, on April 6th.
Scarves and improvised cloth coverings were allowed where purpose-made masks were not available, and medical-grade masks were reserved for health workers.
After the introduction of the mandatory masks, “the number of new infections fell almost to zero”, noted the report, which was written by four academics working in Germany and Denmark and published by an independent research body, the Institute of Labor Economics (IZA).
