Sick Sense

From Activating Evolution

Sick Sense, also called Illness/Germ Sense or Sickness/Illness/Germ Detection or Perception is the ability to detect sickness in subjects. One with this ability gets a gut feeling that a subject is sick (or they can perceive the presence of viruses or bacteria), and the closer they are to the subject, the user can more accurately tell who it is that is sick. Sometimes one with this ability could even tell what the sickness or ailment is, or how long they have been and will be sick.
