What? So all of the health care workers, doctors, nurses, etc wearing mask are making a mistake ?
You should send an email to the entire world.
Wearing a mask doesn’t prevent one from getting a disease. However, if you’re sick, it prevents you from spreading it.

“However, there is no data to suggest that in people who are not infected that they provide any protection to prevent infection.”
