They are only lies if you are too stupid to understand. Which apparently you are. And arrogant as well.
Why dont you tell us why doctors and nurses in hospitals wear masks when they are doing surgery if they serve no purpose.
To prevent saliva and snot from entering an open wound/incision.
If masks work, why are we shut down?
If masks work why are caregivers etc using plastic shields when around Covid-19?
Masks in surgery prevent something from the mask wearer from infecting the person being treated.
Same reason we’re currently being asked to wear masks in stores, etc.
Because they are standing over open incisions. If they suddenly sneeze it’s a lot more serious and unsanitary than droplets on your skin.

Unmasking the surgeons: the evidence base behind the use of facemasks in surgery
The use of surgical facemasks is ubiquitous in surgical practice. Facemasks have long been thought to confer protection to the patient from wound infection and contamination from the operating surgeon and other members of the surgical staff. More recently, protection of the theatre staff from patient-derived blood/bodily fluid splashes has also been offered as a reason for their continued use. In light of current NHS budget constraints and cost-cutting strategies, we examined the evidence base behind the use of surgical facemasks.
Examination of the literature revealed much of the published work on the matter to be quite dated and often studies had poorly elucidated methodologies. As a result, we recommend caution in extrapolating their findings to contemporary surgical practice. However, overall there is a lack of substantial evidence to support claims that facemasks protect either patient or surgeon from infectious contamination. More rigorous contemporary research is needed to make a definitive comment on the effectiveness of surgical facemasks....
snip...It is important not to construe an absence of evidence for effectiveness with evidence for the absence of effectiveness. While there is a lack of evidence supporting the effectiveness of facemasks, there is similarly a lack of evidence supporting their ineffectiveness. With the information currently available, it would be imprudent to recommend the removal of facemasks from surgery. Instead, in the medical field where common practice can so easily become dogma, it is necessary to recognise the constant need to maintain a healthy scepticism towards established beliefs and to periodically re-evaluate and critically assess their scientific merit.
I'm neither stupid nor arrogant. I just despise ignorant tyranny. Why don't YOU tell all the doctors who advise that it is unhealthy for people to walk around wearing masks and those who have studied and found that masks do NOT prevent the spread of viruses that they are wrong, including Dr. Infallible Fauci? I'll go ahead and copy Danny on this, too.
