Prion
Slow, subtle and extremely complex pathogen hidden inside the brain.
Plague Type:	Standard
Plague Cost:	Complete Parasite (Normal or Brutal) or $0.99USD
Released:	May 23, 2012, Version 1.0

Description

Slow, subtle and extremely complex pathogen hidden inside the brain - it is much harder to notice and cure. Disease takes longer to rect to new evolutions. 

Traits

The unique trait that Prion has in Plague Inc is Neural Atrophy, which is like Genetic Hardening, slowing down cure research. The prion also seems to spread slightly slower than most other standard plague types, and as noted in the game, the disease takes longer to react to new evolutions.

Strategy

Please see Prion Strategy Guides.

Trivia

• Real life prions do not contain any DNA, being only proteins. However, in the game, there is a message "Prion DNA detected", a possible oversight by the developer.
• Devolving Neural Atrophy will cause the cure effort to speed up.
• It is also implied that Prions are contagious, when in reality they do not spread unless a person has prolonged exposure to or has ingested part of the corpse of a person with a prion.
• Prions in the real world are responsible for causing Mad Cow Disease, Fatal Familial Insomnia and Kuru disease.
• Prions in reality are incurable and can be sporadic or inherited. However, treatments such as antibodies may be used to treat or cure a prion. So the cure may actually be antibody drugs.
