**UPDATE, Nov. 2021**
Watch a series of brief videos where Tyson Gabriel, an industrial hygienist, safety engineer, and risk manager who trains doctors and has 20 years of experience implementing exposure prevention plans in industry, and is lead researcher for his team, examined each mask study on the CDC’s website. Also see these reports.
Do face masks work? Earlier this year, the UK government decided that masks could play a significant role in stopping Covid-19 and made masks mandatory in a number of public places. But are these policies backed by the scientific evidence?
Yesterday marked the publication of a long-delayed trial in Denmark which hopes to answer that very question. The ‘Danmask-19 trial’ was conducted in the spring with over 6,000 participants, when the public were not being told to wear masks but other public health measures were in place. Unlike other studies looking at masks, the Danmask study was a randomised controlled trial – making it the highest quality scientific evidence. (See link for article)
- Half got 50 disposable surgical masks they were supposed to change after 8 hours. Half didn’t wear masks.
- One month later participants were tested with PCR, antibody, and lateral flow tests and compared with the control group.
- No statistically significant difference was noted in infection rate between the two groups
According to the article authors, these results reflect other reviews and nine other trials have found masks make little or no difference in infection rates.
More importantly there have only been 3 recent community trials showing a “total lack of interest from governments in pursuing evidence-based medicine.”
And the only studies showing any effectiveness in masks have been ‘observational,’ (prone to recall bias) not with a randomized control group, unlike the Danish mask study.
I posted this before, but it bears repeating due to the fact there is 100% compliance in the military population: https://madisonarealymesupportgroup.com/2020/11/17/pro-mask-study-withdrawn-after-virus-spread-in-counties-analyzed-by-researchers/
Similarly to the campaign against HCQ treatment for COVID being maligned, the Danish mask study has also been maligned and picked apart in efforts of trying to downplay it:
