The plague is a dangerous thing show any symptoms in public your liable to get shot or "taken in" if your unlucky..
Eva could hear her name being called probably by the professor. "Eva!" "sleeping in class is strictly prohibited" he would repeat verbatim to yesterday's lecture on her, as she liked to call it "renergizing". After he was done she could finally give her smartass response " but professor if I dont get sleep how else is my immune system gonna ward of the plague" and to this he would walk away not caring enough to attempt a response. These days the plague could be quote "avoided" by taking special immune support pills, but everyone knows they dont do anything much, and once you had the plague there is no helping you though your advised to turn yourself in everyone hides, why because how else would they make that medicine without testing first and only lord knows what happens there which is more horrific than knowing. I no longer need those pills however, why? because I'm already infected.
