In an interview with MDR, Prof. Alexander Kekulé sees face shields as a possible alternative to an everyday mask.
When asked whether a visor protects as well as a mask, he says:🎙
"The classic droplet infection is prevented by the visor..."
"Personally, I think the visor is also a very good thing, because you can see a patient.
"The visor is - apart from this situation when you sit for a very long time and produce this areosol - actually just as good."
In Rhineland-Palatinate, face shields are considered a possible alternative according to the "Mouth-Nose-Coverage Interpretation Guide" on the homepage of the state government.
