Never forget. Especially (small) children and young people as well as older citizens have considerably suffered from the lockdowns and other measures at that time. In real life (at that time), I often observed people and kids wearing masks fitting badly, being too big etc... 1/7

...and thus can hardly filter because of leakages. Therefore, it is extremely important that masks should have different sizes. Shoes also have various sizes and shapes. 2/7

When singing and speaking, the mask also loses its filtering performance after a certain time due to increased humidity. In addition, the former loses function under humid conditions, while the latter operates with a significant air-pressure drop... 3/6

and suffers from relatively fast pore blockage. Alternatively, a biodegradable, moisture-resistant, highly breathable, and high-performance fibrous mask filter may help in this matter. 4/7

In contrast, conventional electrostatic- and nanosieve-based mask filters are single-use and are not degradable or recyclable, which creates serious waste problems. 5/7

At this point, one environmental aspect should not be forgotten that the production and disposal of billions of masks affects the entire globe. The masks were (at that time), for example, often carelessly discarded on sidewalks, in parks and other places (Berlin, Germany). 6/7

When I walk around the city, I still find masks (but much less). See photos in tweet 6/7, taken on February 15, 2023. I also still see chalk drawings of children showing faceless people (but also much less) (photo taken on March 4, 2023). 7/7

Tom Jefferson, senior associate tutor at the University of Oxford, is the lead author of a recent Cochrane review that has ‘gone viral’ on social media and re-ignited one of the most divisive debates during the pandemic - face masks.

German mainstream journalists tried to reinterpret the Cochrane Review (e g. @ChristinaBerndt), which is in my view ridiculous.

#Cochrane found that the meta-analysis could not make a definitive statement on whether measures to support the wearing of masks successfully protected against infections. The study situation was too poor! @Radbruch_lab (German immunologist).

In light of #masks studies. Never forget...
A year ago: And this is what #childrens painted on the streets and sidewalks in Berlin (chalk drawings). I walk > 50 km per week through various neighborhoods in Berlin. #Faceless with and without masks.
