In a new study, Covid uncovered “unequivocal” proof of mask effectiveness.
ANTI-MASKERS were proven wrong after a groundbreaking study in Bangladesh found “unambiguous” proof that surgical masks are extremely effective at stopping the spread of COVID-19.
The results of a randomised controlled experiment, which is the gold standard in terms of quality, revealed that surgical masks are far superior to cloth masks.
The study’s lead researchers are convinced that their findings will put an end to any discussion over mask effectiveness. “This was an exceedingly tough but necessary study to get off,” said Megan Ranney, an emergency care physician and professor at Brown University.
“The anti-mask crowd always asks, ‘Where’s the randomized controlled trial?’ So, there you have it.”
Researchers from Bangladesh and the United States assessed the effectiveness of masks in 600 Bangladeshi communities for this study.
It enlisted the participation of over 342,000 participants, making it the largest-ever randomized experiment on mask use.
Many other factors can mislead observational studies that merely compare mask-wearing behaviors to infection rates in various places.
However, randomized controlled trials, in which patients are randomly allocated to receive or not receive a medical intervention, are considered the most reliable method of gathering evidence.
The issue is that they are both costly and difficult to carry out, especially when it comes to things like mask-wearing.
From November 2020 to April 2021, around 178,000 persons were given the “intervention,” whereas 164,000 were not.
Those in the intervention group received free masks as well as helpful information about the necessity of mask use.
There were also community leaders who were reminding people to wear their masks for an eight-week period in person.
However, those in the control group, the 164,000 persons who did not participate in the intervention, did not obtain any of these benefits.
The researchers stationed monitors in the neighborhood to see how many people were wearing masks and avoiding eye contact in public places such as mosques, markets, and tea stalls.
On a weekly basis, these observations were made.
The researchers questioned participants if they were experiencing any typical coronavirus symptoms five and nine weeks after the studies began.
They then obtained blood samples from the symptomatic patients and analyzed them for SARS-CoV-2 antibodies about 10 to 12 weeks after the experiment began.
The masking interventions resulted in a threefold increase in correct mask use, from to.
