Lethality, before, showing and after evolving necrosis

Lethality is a plague statistic that dictates how deadly the plague is. The more deadly a plague is, the more effort people will put into developing a Cure for it.

At the beginning of a game, lethality is not in any disease unless a deadly symptom like Total Organ Failure, Necrosis, Hemorrhagic Shock or Coma is added. Bio-Weapons will also slowly begin to generate toxins, gradually increasing their lethality unless suppressive abilities are evolved.

Unless special plagues or disease Scenarios are played, killing off all humans is the only way to win the game.


  • It is similar to the Deadliness statistic in the Pandemic flash game.
  • When increasing lethality, the models that represent the player's plague will begin to animate more.
  • Lethality is completely absent in the Santa's Little Helper scenario. All of the symptoms simply don't give any lethality.
