Flu symptoms...sympathetic or parasympathetic?

[SysBio]

Are the responses to pathogen invasion (eg. increased body temperature) initiated by the sympathetic nervous system OR the parasympathetic nervous system?

I would guess that it would be parasympathetic ("rest and digest")...but on the other hand, I could see how it could be a sympathetic ("fight or flight") response too, b/c maybe your body has to work harder to increase its temperature.

Thoughts?

well i would think it's both, and there are a lot of hormones and paracrine signaling molecules that operate to produce flu symptoms..
