True, but it gets to the point of why masks for kids are likely useless. They won't be as effective as the hospital masks and they are never going to get kids to NOT touch them.
Agreed. Nearly all masks that kids wear are likely useless or nearly so for the prevention of COVID for the wearer, but that is a different point than pretending that wearing masks increases the likelihood that children will come into contact with potentially dangerous viruses or bacteria.
This is sensationalist propaganda written specifically to cater to certain ideological biases with a candy coating of scientism, just like a bunch of the junk from the other side of the debate ... although perhaps with fewer of the trappings of credibility offered by the source. The argument could be equally made that pathogens found on the used masks are pathogens that didn't make it into the body so hooray for masks. In fact, had the results been that no pathogens were found, we'd likely be reading an article about how the masks failed to catch even one nasty thing so they were useless.
We normally don't require kids to strap a dusty keyboard to their face.
Do we require kids to wash their hands after using a computer? If not, it's essentially the same thing.
