Here is a link to an attorney's summary of the penalties:

And the section itself:

This appears as if it will be charged as a Felony 2. I suspect that there might be case law that defines the emitting of bodily fluids as being covered by this section. If not, then your attorney can probably negotiate this down to a lesser offense.
