Pegboard invented to prevent spreading leprosy?

There’s a difference between a cure and something that prevents contagion, nevertheless I’ll be darned if I can see how pegboard could be either. I’m also at a loss to imagine how it could be created accidentally.

Perhaps as alluded by DrCube this is that rarest of internet creatures – a made-up story so flagrantly and egregiously ridiculous that no one got suckered into believing it.
