According to the website that broke this, two separate co-workers at Alcon have confirmed that there was an email put out by Alcon MANAGEMENT stating that an Alcon was exhibiting "Ebola-like symptoms." Her boyfriend works there, and reportedly, so do her parents.
Unless everyone is lying, someone is at least symptomatic - possibly infected.
Or maybe has the flu or a common cold....since those are going around currently (my daughter just got over a nasty case of influenza....and yes it was tested for)
