Question about an 80's Sci-fi Movie, where there was an outbreak of a Virus in a Lab...?

Question

...and the virus basically turned everyone insane killing the non infected ones. And the only way you can tell who were infected was by shining a "Black Light" in their faces and there was an eerie glow. To add more info in this movie, the only one who is not infected in the Lab was a female security guard. In which they were all baffled why she was not infected, turns out she did not know she was pregnant thus the proteins and antibodies in her blood. The ending was they created an antivirus and started injecting the infected ones, thus a fight in the Laboratory ensues. Any ideas on this title? I remember this movie as clear as day, but could not remember the title. I have wanted to add this to my collection, please help.

Answer 1

...the plot sounds pretty damn familiar; if I was to shoot from the hip, with regards to answering this question, I'd be inclined to toss out the possibility that the film you're talking about is....."Warning Sign", from 1985.

Answer 2

The story line doesn't quite match that of The Andromeda Strain (1971). I've seen that movie several times and, at first, the only two people of the town of Piedmont that are non-infected are the old, town drunk and the baby. It had something to do with their high blood-oxygen levels. I don't remember any female security guard, especially one who didn't know she was pregnant.

Answer 3

I've seen it and it's not the Andromeda Strain.In the end there are some people outside that want to open the laboratory, because their families work there, and when they open it, inside theyalready have the cure. It's this one right? I have to think about it, and I'll get back to you.

I think it's "Warning sign", the dude below is right

Answer 4

The Andromeda Strain? That is my guess...
