[Name] Stigma [Source] Trauma Center: New Blood [Symptoms] 
A virus accidentally created by Markus Vaughn and Lloyd Wilkens. It islater used as a bioterror weapon by the group Parnassus. It comes in six strains, named after body parts it resembles or attacks (Cheir, Soma, Ops, Onyx, Brachion, Cardia). Unlike other pathogens, which store their genetic information in DNA, Stigma stores its genetic information in a film-like structure making it unique among pathogens. Due to the fact that Stigma originated from a lab rat with Culurium-based synthetic blood, a newly discovered mineral from the country of Culuruma, taking control of the mines that contain the mineral is necessary for the mass production of Stigma.
