I confess that I have difficulty distinguishing one Ministry department from another sometimes, Arthur. From the outside it all seems rather Byzantine.

Does Griderson have a reason for expecting the disease to affect no one beyond the Muggles who are current ill with it? The flea theory in no way ensures this. And does your colleague Brownmiller have a special reason for expecting it will spread beyond the camps?

I myself would expect that any disease afflicting Muggles could equally infect any person, magical or otherwise. From a medical point of view, that ought to be a baseline assumption. Unless there is some special reason to believe that magic makes a difference in the specific way that the disease attacks the body. There are, of course, magical ailments that seem not to affect Muggles, and there are infections we are able to protect against with magic, but in almost all respects the human body is the same whether a person possesses magic or does not.

And so I wonder: does someone know something beyond what we've heard?
