Well, yes, but it's a different type of "supernatural."
I'm... honestly unclear what you mean. I don't think "a different type of supernatural" is all that meaningful, in the Dresdenverse.
One can dice it finely: point to faeries as one type (or several, mincing finer than we diced), and ghosts as another type, ghouls as a type, etc etc etc.
I don't see anything about Rampires that silo's them uniquely into a "different type" from any of those many other different types.
Red vamps aren't human anymore, where a wizard is kind of "human with an upgrade." And half-Ramps like Susan are caught halfway between human and other... or maybe just frozen mid-transition.
A half-ramp is arguably also kind of a "human with an upgrade!"
A Ramp-attack infects the victim with a "Rampire Spirit," more or less. It seems to be a psychic version of what a Tarantula-wasp (or a xenomorph from Alien) does. Until the victim kills somebody (and the spirit hatches) they are still essentially human.
It's been a long time since I've read the earlier books, but if I'm remembering right, Susan only had partial Ramp abilities
Physically, Susan was able to go toe-to-toe in combat with a full Rampire; half-ramp speed & strength was 100% of full-ramp speed & strength. Her narcotic/addictive pleasure-saliva wasn't as potent as a full Ramp, but it was strong. She was much much tougher than a human, but not as tough as a Ramp (a hollowpoint round to the heart would kill her instantly, but a Rampire could recover).
Basically, she had most of the Rampire power-ups, but not the immunities (nor the weaknesses -- a deep gut-wound would take the Ramp's blood reservoir; but Susan could regenerate from almost any wound that left her alive (if she could get a little bit of blood)).
The half-Ramp's also have the horrible blood-lust of the Rampire-larva to contend with, and violence (or violent emotions (including erotic desire)) can make that
much worse.
