New Brevoort Formspring

Not trying to nitpick, but I'm sooooo confused... when and where will we get the particulars of the M-pox explained to us? I only ask because Uncanny X-Men and ANAD X-Men have mutants hanging out on Earth, a-ok, but Extraordinary would suggest this is a highly dangerous move. Can you clarify it for me or point me in the right direction for clearer answers, I'm very confused and I've been reading about mutants since I was a baby.
