Diaper rash can lead to death?

My friend just sent this link to me. And while it's sad in its own right, I'm honestly more amazed that prolonged diaper rash can result in dehydration and death.

What's more amazing is how INCREDIBLY LAZY one would would have to be to decide not to clean their kid's bum for SO LONG that it results in fatal diaper rash.
