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 government 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 lives in tons of animals and normally don't kill its animal hosts. Any animals that eats it keeps the eggs of it in it's stool. Similar to bacteria E Coli,, it infects food from touching infected animal's stools or eating uncooked or unclean food. (breads, cereals, pasta, beans and nuts and seeds. Meats, dairy and dairy products, eggs and fish (Like sushi) all have parasites. Eating certain with parasites can lead to stomachache, diarrhea, nausea and vomiting. Not to be confused with worms.

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.
