General Information

« There are around 300 fungi identified as pathogenic to humans. Typically 2-10 micrometers in length, they spread via fungal spores and can produce lethal mycotoxins. »
— Fungus Description, in the Plague Inc.: The Board Game

The Fungus is an unlockable plague type in Plague Inc. and Plague Inc: Evolved. The fungus is the third plague in the Main Game, but in Cure Mode it is the fourth.


  • Like the previous two plague types, the Fungus plague type has all the same Transmissions, Symptoms, and Standard Abilities, as well as the same possible Genes.
  • The disease spreads through the spores it releases which are generally poor in traveling.
  • One Unique ability, Spore Burst, allows it to infect a random, uninfected country.
  • Another ability, Spore Hardening, allows spores to ignore a good portion of climates which makes the Fungus very infectious late in the game.
  • Spore Eruption, a unique ability, allows multiple uninfected countries to be infected at once.

Special Abilities

  • Spore Burst (1) Releases a small amount of spores that will infect a random, uninfected country.
  • Spore Eruption (2): Releases a huge amount of spores that will infect multiple, uninfected countries.
  • Spore Hardening: Spores become more climate resilient and will continuously infect uninfected countries.



  • Cannot inherently infect other countries without carriers or Spore Burst/Eruption/Hardening abilities.
  • Extremely slow transmission rate (1/10000th of a regular plague air/sea/land base rate).
  • Relying too much on Disease spreading traits may not allow evolution of high tier symptoms. Using the gene Patho-Stasis can reduce this which makes it easier to evolve all the Spore Bursts without draining DNA Points. However, using Patho-Stasis increases the chance that you won't be able to get that much-needed lethality after you've infected almost everyone.
  • This plague type is one of the longest and most frustrating plague types to beat due to how slowly it spreads even with the use of Spore Burst/Eruption/Hardening abilities.
  • Considerable penalty to effectiveness in arid countries.
  • This pathogen is arguably the most luck-based plague in the game, as the Spore Bursts infect countries in a 100% random manner. If you are unlucky, you may not infect island countries before the cure progress reaches 100%.
