You're as bad as aquascoot.
How many times have you (and others) posted that picture here?
Seriously - how many times does it need to be said that surgical 'baggy blue' masks are not designed to stop the spread of respiratory viruses?
However, they are better than nothing - assuming they're worn correctly (no 'dick noses' or 'chin nappies').
And, how many times does it need to be said that the Cochrane Review has been misinterpreted?
What the Cochrane Review Says About Masks For COVID-19 — and What It Doesn’t Quote:People online are touting the results of a Cochrane review to incorrectly claim that it shows masks “don’t work” against the coronavirus. But the primary conclusion of the review is that it’s uncertain from randomized controlled trials whether mask interventions in the community help slow the spread of respiratory illnesses.
"People online"... yes, that would be the antimaskers, antimaskers and conspiracy nutters on social media.
Quote:The Jan. 30 review found that based on existing randomized controlled trials — which tested the effectiveness of interventions encouraging people to wear masks, rather than testing the effectiveness of masks themselves — wearing masks in the community “probably makes little or no difference” to the number of people with influenza or COVID-19-like illnesses.
“The pooled results of RCTs did not show a clear reduction in respiratory viral infection with the use of medical/surgical masks,” the review reads.
The authors, however, also emphasized the “uncertainty about the effects of face masks.” And only two trials in the review assessed the effectiveness of a mask intervention for COVID-19.
“The high risk of bias in the trials, variation in outcome measurement, and relatively low adherence with the interventions during the studies hampers drawing firm conclusions,” the authors wrote. “The low to moderate certainty of evidence means our confidence in the effect estimate is limited, and that the true effect may be different from the observed estimate of the effect.”
In other words, there isn’t good evidence from randomized controlled trials that encouraging mask use in the community prevents the spread of respiratory diseases, but the issue also hasn’t been studied very well. So the real answer is unknown.
Despite the limitations, many people misinterpreted the review to be saying that masks “don’t work.”
I'm sure we'll be doing this again soon... what the heck is wrong with you people? Amnesia? Covid brain
fog damage? Trolling? Does anyone know?
