Also, this is subtle and maybe overthinking, but... why even mention illness / flu?
Just use any other vague, perhaps business related excuse for not being around... don't spoil the mystery with imagery of you weak, with chills, coughing and moaning.
Ironically, once you've converted a girl, the thought of you with the flu sends her spinning to please you with homemade soup and delicate bj's.
Sounds like she was on the fence and maybe it would not have mattered anyway -- but it doesn't help to be "that sick guy I haven't fucked".
