You asserted a study supports your position, claimed it was the gold standard of studies, yet provided no receipts.
I literally provided what is the gold standard of medical studies and the receipt, it unequivocally refutes you.
Your response is to then employ ad hominem character attacks and still no receipts.
Full disclosure, my wife is an RN who for years before covid frequently worked with actual isolation patients, we are very aware of what works and does not work and when such protective measures are employed. Here is a shocker, covid somehow changed all the established practices, never before would a nurse rely on a surgical mask for an isolation patient, but somehow for covid that was enough. Also if you know anything you should be aware covid can also transmit via the eyes, actual protective measures should include a face shield or goggles but I am sure that is not important to you, only your sacred false narrative.
Pretty obvious who is full of shite here.
First off what you cited was not a study and certainly not a “gold standard study” LOL.
What you cited was an analysis of 78 different UNCONTROLLED studies conducted around the world. UNCONTROLLED means that those conducting the studies had no way to measure the behavior of the participants which could have skewed the results, they could not monitor the participants diligence or aptitude in using masks, nor did any of the studies control for incidental contact versus long term contacts. Not doing that basically makes those studies worthless as to determining if masks provide any protection against Covid19.
A mechanical study actually measured the percentage of virus detected passing through a mask during a given time in a closed environment. This was highly controlled and measured and showed that while masks do not stop all virus particles from passing through, they do stop enough (through moisture adhesion and static electricity) to infer that a mask provides some temporary protection. Very temporary and short term as I stated before. Masks provide no protection for contacts of anything over an hour and usually much less time than that.
I am not even advocating people wear masks unless they are in very specific criteria. Personally I could care less if you or anyone else wears a mask. I am amazed however at the hysteria both pro and anti mask, where people discard any semblance of reason and instead adhere to rigid positions where they only believe what they want to believe.
