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.

https://pubmed.ncbi.nlm.nih.gov/19193267/, 2009

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.
