    wissenschaftlicher Beweis

    Außerhalb von Mathematik ist die wissenschaftliche Beweislage meistens durch Statistik gegeben (außer in der Physik, da kann man sich die Statistik manchmal sparen). Studien und Metastudien sind in der Epidemiologie wahrscheinlich das höchste der Gefühle. Etwaige prä-2019 Studien darfst du hier gerne verlinken. Meiner Erinnerung nach waren sich auch die Experten 2020 nicht einig, ob Masken effektiv sind.

    Edit: Ganz abgesehen davon dass das von meiner Grundkritik wegläuft: Ich denke nämlich nicht, dass die “Pikachugesicht” und “Nein-Doch-Oh” Fraktion hier wahnsinnig gut über prä-2019 Studien zur Effektivität von Masken informiert ist bzw. war.

      Normalerweise muss man sich natürlich das Fazit durchlesen, nicht das Abstract, deshalb kannst du diese Belegstellen natürlich allesamt ablehnen (erste 30 Einträge der verlinken Suchanfrage bei PubMed):

      klapp mich aus:

      Cough etiquette, use of face masks and hand hygiene are the most important measures to reduce the risk of infection transmission from person to person.

      https://pubmed.ncbi.nlm.nih.gov/27641976/, 2016

      However, during a severe pandemic when use of face masks might be greater, pandemic transmission in households could be reduced.

      There is some evidence to support the wearing of masks or respirators during illness to protect others, and public health emphasis on mask wearing during illness may help to reduce influenza virus transmission. There are fewer data to support the use of masks or respirators to prevent becoming infected.

      https://pubmed.ncbi.nlm.nih.gov/20092668/, 2010

      Wearing a face mask was a protective factor against influenza infection. We recommend a more comprehensive intervention study to accurately estimate this effect.

      https://pubmed.ncbi.nlm.nih.gov/23968983/, 2013

      Mask use also reduces the reproduction number, possibly even to levels sufficient for containing an influenza outbreak.

      https://pubmed.ncbi.nlm.nih.gov/20497389/, 2010

      Tightly sealing a mask to the face blocked entry of 94.5% of total virus and 94.8% of infectious virus (n = 3).

      https://pubmed.ncbi.nlm.nih.gov/22460981/, 2012

      The median-fit factor of the homemade masks was one-half that of the surgical masks. Both masks significantly reduced the number of microorganisms expelled by volunteers, although the surgical mask was 3 times more effective in blocking transmission than the homemade mask.

      https://pubmed.ncbi.nlm.nih.gov/24229526/, 2013

      This implies that measures to reduce transmission by contact or large droplets may not be sufficient to control influenza A virus transmission in households.

      https://pubmed.ncbi.nlm.nih.gov/23736803/, 2013

      Overall, although hand hygiene compliance is high among pilgrims, face mask use and social distancing remain difficult challenges. Data about the effectiveness of these measures at the Hajj are limited, and results are contradictory, highlighting the need for future large-scale studies.
