Is the initial Fortitude save to negate the effects of the contagion spell based on the level of the spell and the caster's casting stat, or is it based on the disease itself?
Range touch
Target living creature touched
Duration instantaneous
Saving Throw Fortitude negates; Spell Resistance yes

Use the disease's listed frequency and save DC to determine further effects.
Initial disease infliction is determined by the combination of spell level and ability score, like normal. Further checks against the disease are done as per the normal form of the disease.
Thanks for the reply.
