Other mistake: The plot of this film can't seem to make up its mind whether or not the Cedar Creek virus is airborne or not. Several scenes show characters walking around in infected areas with and without protection in the same area. At one point Casey's suit breaks implying that he immediately contracts the virus within mere seconds without even having breathed it in yet we see other people walking around with either their face or eyes unprotected.
Other mistake: About half an hour into the film, Schuler and Daniels go down to the level 4 bio-lab. They pass through a number of doors that earlier and later in the film reqire an ID card or hand-print scan to access, but they don't use either on any door. (A security guard seems to usher them through one door, but surely such a high security lab would require positive ID at each entry point).
Answer: Yes, the fictional virus would be a filovirus similar to Ebola. These are filament shaped virus that can coil up.
