For decades, dozens of scientific papers have suggested that masks are ineffective at preventing disease transmission. Both the WHO and Dr Fauci corroborated that claim as recently as March 2020. In that same month, there was a sudden flip, we were told that masks would protect us from COVID, despite claims to the contrary from the mask manufacturers. By September 2020 the head of the CDC claimed in testimony before a US Senate subcommittee, that masks were more effective at preventing COVID than vaccines.
Despite the now “conventional wisdom” that masks prevent the spread of viruses, there are numerous studies that show they do not. Interestingly, there is even research showing that operating-room personnel’s face masks during surgery had no effect on whether the patient developed a subsequent infection.
The CDC’s own data reveal that those who wear masks get infected with COVID at the same rate as those who don’t. Indeed, 85% of those infected with COVID wore masks some or all of the time before their infection.
Countless jurisdictions that mandated masks actually saw an increase in infections during the mandates compared to non-mandated jurisdictions.
Only two randomized controlled studies were conducted during COVID. The first in Denmark found no benefit in mask-wearing, and the second conducted in Bangladesh  concluded that there was a small benefit to using medical masks, but not with cloth masks. The masked group of 178,322 participants had just 20 fewer symptomatic infections than the control group – over an 8 week period. The study’s methodology and conclusions were criticized from a number of angles.">https://www.justfactsdaily.com/famed-bangladesh-mask-study-excluded-crucial-data[/fn]
Even if masks were slightly effective, one must also consider the negative effects of continuous mask-wearing. These include a decrease in oxygen intake levels,[/fn]N95 masks are estimated to reduce oxygen intake by anywhere from 5 percent to 20 percent. That’s significant, even for a healthy person”

A randomized controlled study conducted prior to COVID compared cloth vs medical vs no mask and concludes “as a precautionary measure, cloth masks should not be recommended.” Since with cloth masks, participants also had “significantly higher rates of ILI [Influenza like Illnesses] compared with the control [who did not use any mask].” 
During COVID, a study of over 35 European countries showed that there was no statistically significant correlation between masks and COVID infections. In addition, the study concludes, "the moderate positive correlation between mask usage and deaths in Western Europe also suggests that the universal use of masks may have had harmful unintended consequences."[fn]https://www.cureus.com/articles/93826-correlation-between-mask-compliance-and-covid-19-outcomes-in-europe#:~:text=The%20findings%20presented%20in%20this,European%20wave%20of%20COVID%2D19.
