The Parasite is an unlockable plague type in Plague Inc. and Plague Inc: Evolved.

Unlike other pathogens, the parasite and its style of life prevent it from passively gaining DNA points from infections and has a much higher starting Severity than usual.

Like the previous three disease types, Parasite has all the same Transmissions, Symptoms, and Abilities. Its unique Ability Symbiosis lowers its Severity, which is vital for it to spread far before the governments of the world notices it. It also gains a large number of DNA from orange bubbles, allowing it to improve its Transmission ability and the lethality of its symptoms.

In real lifeEdit

Parasites are organisms that depend on a host for survival, to the disadvantage of the host. They usually do not kill their host (those who do are called parasitoids), often living on it for extended periods of time. Transmissible parasites may be transmitted directly (e.g. head lice), by being ingested by a host through contaminated food or water (e.g. round worms), or by intermediate hosts transporting them between definitive hosts (e.g. malarial parasites being transmitted between humans by mosquitoes). Human parasites include fleas, lice and various kinds of parasitic worms, among diseases caused by parasites are malaria, amoebic dysentery, sleeping sickness and amoebic meningitis.

Special AbilityEdit

  • Symbiosis 1-3: Makes the parasite more in tune with its respective host, so it gets harder to detect and cure. Symbiosis 2 and 3 also increase infectivity. Devolving this can cause heightened severity. 


Please see Parasite Strategy Guides.


  • Unlike conventional parasites whose goal is to live off the host for as long as possible, Plague Inc's version of a parasite is more similar to a parasitoid, which eventually kills off its hosts.
  • The Parasite was one of the 3 plagues from Pandemic, the spiritual predecessor to Plague Inc, alongside Virus and Bacteria.
