Disease

Diseases are some of the most serious medical problems that NPCs can face in Outer Colony.

Summary

  • Humans can contract diseases from a variety of sources. Diseases can spread through proximity to other diseased people, or from exposure to unburied, rotting corpses.
  • Diseases sap the physical and mental strength of afflicted people.
  • When untreated, particularly severe diseases can kill people.
  • Diseases affect people of different age states differently. The very young and very old are much more likely to die from infections.
  • Diseases progress through stages, with their effects waxing and waning throughout their lifecycles.
    • When a person first contracts a diseases, it begins an incubation period. The person exhibits no symptoms, but the disease can spread to others during this phase. This makes the incubation extremely dangerous to the health of your colony, as an affected person who enters a densely packed socialization area could cause serious problems.
    • After the incubation period, symptoms will begin, damaging the infected person’s physical and personality values.
    • If the disease doesn’t kill the person, it will eventually dissipate on its own.
  • After a person has survived a disease, they will develop an immunity to it.
  • When a human realizes that it’s diseased, the human will go to an open hospital bed, if one is available, and will wait for treatment.
  • If a disease cure is available, a doctor on his work shift will treat the patient.

Understanding Disease Information

Diseases in Outer Colony have many properties, and different NPCs are affected in different ways. When considering the effects of a particular disease, keep the following factors in mind:

  • Each disease type has a set of physical traits and personality traits that it affects. Normal effect values for these traits are reported in the disease’s entry in the encyclopedia dialog.
  • Each disease type has a lethality rating. This describes how likely it is to kill a normal, healthy adult at the peak of the infection’s lifecycle. A higher rating means more likelihood to cause death.
  • A disease type has an “Onset of Symptoms” rating. This describes the length of the disease’s incubation period. The higher the rating here, the longer the incubation period.
  • Disease can have cures. The item needed to cure a disease is reported in the encyclopedia dialog.
  • Diseases also have standard durations. This is a measurement of how long the disease typically lasts, if allowed to run its course naturally.

Bear in mind that the young and old are usually impacted more severely by diseases than normal adults.

If your colony has a strong medical infrastructure with many hospital beds, well trained doctors, and large numbers of disease cure items, it can weather a disease outbreak well. If you have none of these things, it’s likely that an outbreak of plague will doom your settlement.
