Are you astonished to see this study finding little to no benefit from masks on the CDC website: https://wwwnc.cdc.go...19-0994_article ?

 

" Although mechanistic studies support the potential effect of hand hygiene or face masks, evidence from 14 randomized controlled trials of these measures did not support a substantial effect on transmission of laboratory-confirmed influenza. "

Are you astonished to see this study finding little to no benefit from masks on the CDC website: https://wwwnc.cdc.go...19-0994_article ?

 

" Although mechanistic studies support the potential effect of hand hygiene or face masks, evidence from 14 randomized controlled trials of these measures did not support a substantial effect on transmission of laboratory-confirmed influenza. "

 

This study reports that  "Finally, although our review focused on nonpharmaceutical measures to be taken during influenza pandemics, the findings could also apply to severe seasonal influenza epidemics. Evidence from RCTs of hand hygiene or face masks did not support a substantial effect on transmission of laboratory-confirmed influenza, and limited evidence was available on other environmental measures."

 

Did you read the details noted about face masks? "We did not consider the use of respirators in the community. Respirators are tight-fitting masks that can protect the wearer from fine particles (37) and should provide better protection against influenza virus exposures when properly worn because of higher filtration efficiency. However, respirators, such as N95 and P2 masks, work best when they are fit-tested, and these masks will be in limited supply during the next pandemic. These specialist devices should be reserved for use in healthcare settings or in special subpopulations such as immunocompromised persons in the community, first responders, and those performing other critical community functions, as supplies permit.

 

"In lower-income settings, it is more likely that reusable cloth masks will be used rather than disposable medical masks because of cost and availability (38). There are still few uncertainties in the practice of face mask use, such as who should wear the mask and how long it should be used for. In theory, transmission should be reduced the most if both infected members and other contacts wear masks, but compliance in uninfected close contacts could be a problem (12,34). Proper use of face masks is essential because improper use might increase the risk for transmission (39). Thus, education on the proper use and disposal of used face masks, including hand hygiene, is also needed."

 

While numerous studies have supported benefits from proper use of good masks to reduce the spread of Covid-19, this is a far cry from convincing evidence that it is useless and not in the service of public health.

A lot of words to say that the current masking protocol is useless to prevent viral transmission. The sentence I quoted summarizes that the evidence from 14 randomized controlled trials did not support a substantial effect on transmission of laboratory-confirmed influenza viruses. Are you trying to imply that because the available data are from influenza viral transmission that they don't apply to Covid? If so why?

 They are not just a lot of words. Their concern is that good masks would not be available, would be costly, that people wouldn't comply or use them properly, and that they should be reserved for use in healthcare settings and during proximity to immunocompromised people.  They reported that there were no "substantial" effect on transmission in their lab studies but also that many of these were not controlled for the types of masks used. If you're convinced that you can pull one sentence out of an old study with limited data and ignore even those details, there's nothing I can say to convince you otherwise. We have very different concepts of what evidence means.
