Fever is a tier 3 symptom, and a tier 2 symptom in some other diseases, such as the Simian Flu DLC and the Necroa Virus DLC. It increases body temperature, contagiousness, and severe dehydration. It slightly increases disease lethality and Infectivity, although it is more lethal than Paralysis.


  • Along with Diarrhoea, Tumours and Inflammation, Fever is one of four symptoms which can be better understood by scientists during a game, making a plague easier to cure when it is evolved or mutated.
  • In the Black Death scenario, it is automatically evolved at the start of the game.
