Ik ging vandaag ingaan op Mondmaskers... Zo een heikel topic, u weet wel. Ik ga dat doen obv een literatuurstudie (cato.org/sites/cato.org…). Deze studie bekijkt tientallen onderzoeken en vormt daar een kritische mening over. Ik citeer het "abstract" even letterlijk
The use of cloth facemasks in community settings has become an accepted public policy
response to decrease disease transmission during the COVID-19 pandemic. Yet evidence of
facemask efficacy is based primarily on observational studies that are subject to confounding and

on mechanistic studies that rely on surrogate endpoints (such as droplet dispersion) as proxies for

the best available clinical evidence has mostly failed to show efficacy,

estimates of amount of benefit be truthfully communicated to the public.

Nu zal ik dat even doorvertalen... Met wat cijfers
Minstens 38 studies (zie bron) kunnen amper of geen "statistisch significante" vermindering in zien door het louter dragen van een mondmasker. 6 studies tonen in minder of meerdere mate aan dat het dragen van een mondmasker kan gepaard gaan met net hogere secundaire infectie.
Ik wil er nog aan toevoegen: 1) swprs.org/face-masks-and… sugerreert exact dezelfde conclusie en 2) Ondertussen weten we dat aerosol transmissie van dit virus erg waarschijnlijk is, ergo, partikels zo klein dat de meeste mondmaskers dit niet kunnen filteren
In oktober 2020 werd ook onderstaande studie gepubliceerd: ncbi.nlm.nih.gov/pmc/articles/P…
Deze stelde duidelijk dat de mode van transmissie beter onderzocht moest worden en dat sommige richtlijnen met elkaar conflicteren.
