<onlyinclude>[[Colonist]]s sometimes contract diseases. Diseases most often occur through random [[events]] that vary by [[Biomes|biome]] and [[AI_Storytellers#Difficulty|difficulty]]. [[Disease#Infection|Infections]] have a random chance of developing from an [[injury]] regardless of biome.</onlyinclude>
+
'''Diseases''' are temporary and treatable ailments, that pass away after a certain amount of time or treatment.
  
* Note:  Infectious diseases are acquired from the world environment, not other "sick" pawns. In RimWorld, no disease is "contagious"; that is, just because a colonist becomes infected with a disease, they are not "carriers" who may make others sick. There are some diseases that are known to strike groups of colonists at the same time (e.g. [[gut worms]]), mimicking an outbreak, but pawns can be safely exposed to another pawn that has flu or plague or any ailment without fear of "catching the disease" from that source.
+
== Contract ==
 +
Most diseases are contracted as part of an [[event]]. Your colony's [[biome]] determines how common diseases are, as well as how common each disease is. However, some diseases happen situationally, regardless of biome:
 +
*[[Infection]] may occur after a bleeding [[injury]], burn, or frostbite is inflicted. Tending the injury in a clean room reduces the chance of infection.
 +
*[[Lung rot]] occurs randomly when inhaling enough [[rot stink]].
 +
*[[Blood rot]]{{RoyaltyIcon}} and [[paralytic abasia]]{{RoyaltyIcon}} are exclusively part of [[quest]]s, while [[infant illness]]{{BiotechIcon}} can only happen during [[Reproduction#Birth|birth]].
  
==Effects==
+
Note that diseases are '''not contagious''' in RimWorld. Disease does not ever spread between colonists, though disease events often simulate "outbreaks" by inflicting multiple colonists at the same time.
Diseases cause infected colonists to suffer symptoms, which can vary from disease to disease. Diseases progress through stages of intensity until either the colonist develops immunity or the disease runs its course, usually leading to death. Diseases progression generally follows a pattern of minor -> major -> extreme. The more severe the disease, the more dramatic the symptoms. Diseases are not contagious and do not spread between pawns.
 
  
==Treatment==
+
The drug [[penoxycyline]] protects against [[Malaria]], [[Plague]], and [[Sleeping sickness]]. The disease event still happens, but colonists will not be affected.
At regular intervals, a [[rest]]ing colonist can be treated by a [[Skills#Medicine|doctor]]. This slows the progression of symptoms and for most diseases it is critical to treat the colonist as often as possible.  You cannot give a new treatment until 3 hours before the expiry of the previous one, and you can see the remaining time by hovering over the disease in the colonist's '''Health''' tab. The treatment interval varies for each disease.
 
  
'''Treatment Quality''' is determined by a variety of factors, including the doctor's [[skills|skill]] and the quality of [[Doctoring|medicine]] used. Progression of the disease is slowed depending on how good the treatment was.
+
== Summary ==
 
+
Humans and animals can get diseases. Most diseases uses the ''severity'' mechanic. As a disease progresses, its symptoms progressively get worse. If a fatal disease's severity reaches 1.0 (100%), then [[death]] occurs. Most diseases go from minor -> major -> extreme. How fast a disease progresses depends on the disease itself.
'''Immunity:''' Colonists will gradually develop immunity to potentially fatal diseases, such as wound infections or [[Disease#plague|plague]]. When immunity reaches 100%, the symptoms will not immediately disappear, but will instead tick backwards towards zero with the colonist no longer needing any treatment. If the disease symptoms progress past 100% before immunity does, the colonist will [[Death|die]].  [[Immunity Gain Speed]] is affected by the colonist's food, rest, bed quality, age, and [[blood filtration]].
 
 
 
'''Blood Filtration''' is a major factor in getting better from diseases. Poor blood filtration may result in sicknesses developing faster than they would usually. Older colonists are more susceptible to sickness than younger ones.  Colonists with only one [[kidney]] have their blood filtration reduced by 50%.
 
 
 
==Diseases==
 
Most diseases have the following:
 
*General Symptoms - initial symptoms that develop in the first few days of being sick.
 
*Advanced Symptoms - symptoms that set in when the disease progresses for any reason (e.g. being untreated or gets worse).
 
*Treatment - some illnesses are treatable with medicine, but not all diseases are treatable, especially [[ailments|chronic diseases]].
 
  
 +
== Diseases ==
 +
'''Note:''' Base values of severity and immunity gain speed used in the table.<br>Treatment's reduction of severity depends on tend quality. 50% tend quality equals half the reduction.

==Fatal diseases==
+
== Treatment ==
<!-- This is not strictly "alphabetical"; Infection is first, as it is the most common and not technically a "disease" per se; Scaria is last, as it only affects animals.-->
+
Most diseases can be tended to, just like an [[injury]] or [[ailment]], by a [[Doctoring|Doctor]] pawn and when the afflicted pawn is assigned to [[Work|Patient]] themselves. Tend Quality is determined by a variety of factors, including the doctor's [[skill]] and the quality of [[Medicine]] used. Generally, higher quality tends reduce the total time until recovery, though mechanics vary. How often a disease can be tended depends on the disease itself.
 
 
Though not all are technically "diseases", the ailments below all have the potential to kill if not treated adequately.
 
 
 
===Infection===
 
{{Main|Infection}}
 
  
Not to be confused with "infectious diseases", in RimWorld an "infection" is a specific ailment which can occur in open wounds, frostbite, and burns which have either been left untreated or were treated in unsanitary environments. Progresses and kills rapidly if poorly treated.
+
There are 3 types of diseases to tend to:
 +
* The disease will progress over time, and treatment slows down progression. Immunity is gained over time, dependent on [[Immunity Gain Speed]] and independent of tend quality. Once immune, the disease will slowly fade and the colonist will stop being a patient. This applies to most fatal diseases, including the [[flu]], [[infection]], and [[plague]].
 +
* The disease does not progress. Treatment must reach a ''total tend quality'' (300%) before the disease is cured. For example, 4 tends at 80% quality would equal 320% total tend quality. Applies to [[gut worms]] and [[muscle parasites]].
 +
* The disease progresses over time, and treatment slows and even prevents progression. The disease fades only after a certain time. Applies to [[lung rot]], [[fibrous mechanites]], [[sensory mechanites]], and [[blood rot]].{{RoyaltyIcon}}
  
General Symptoms:
+
Certain diseases have specialized cures. For example, [[infection]] in a non-vital part can be cured by amputating or [[Artificial body part|replacing]] a limb, [[blood rot]] can be instantly cured with [[glitterworld medicine]], and [[gut worms]] can be treated by replacing the stomach. In addition, a [[healer mech serum]] immediately cures any disease.
*Mild pain
 
*Reduced Consciousness
 
  
Advanced Symptoms:
+
=== Immunity gain ===
*Loss of Consciousness
+
{{Main|Immunity Gain Speed}}
*Excruciating Pain
+
Some diseases are a race between the increasing severity of the disease and the increasing immunity to it. This immunity gain is controlled by several factors:
*Breathing difficulties
+
* Base immunity gain speed for the particular disease.
 +
* InfectionLuck, an uncontrollable generated value that adds randomness to the diseases progression. Each disease has a variance in Immunity gain speed of 20% up or down.
 +
* The [[Immunity Gain Speed]] stat of the patient
  
Treatment:
+
Immunity Gain Speed is affected by the following:
*Medicine
+
* '''[[Food]]''': Pawns above 12.5% [[Saturation]] do not have any penalties to immunity.
*Amputating the affected part
+
* '''[[Rest]]''': Actively resting gives a bonus to speed. Resting in any [[bedroll]] or [[bed]] increases the stat, a [[hospital bed]] increases it further, and a hospital bed with an attached [[vitals monitor]] increases it the most.
 +
* '''Age''': As a pawn gets closer to and past their species' life expectancy, immunity gain speed decreases.
 +
** For baseline humans, immunity gain speed is gradually lost after age 54. [[Genes]]{{BiotechIcon}} like [[Genes#Mild cell instability|cell instability]] can affect the pawns lifespan and, in turn, affect this progression.{{Check Tag|Verify|Verify and also confirm on Immunity Gain Speed page}}
 +
* '''[[Blood Filtration]]''': Mostly increased via [[luciferium]]. Reduced with [[kidney]] or [[liver]] damage, slightly improved with a [[detoxifier kidney]]{{BiotechIcon}}.
 +
* '''Direct boosts''': The [[Super-immune]] trait, [[Immunoenhancer]]{{RoyaltyIcon}}, and [[gene]]s{{BiotechIcon}} can increase immunity speed.
  
 +
Note that these only apply to diseases with immunity mechanics. For example, you don't need to give a pawn with [[gut worms]] bedrest.
  
===Blood rot===
+
== Disease frequency ==
{{Main|Blood rot}}
 
  
A bacterial disease that has little effect on host at first, but kills quickly if left untreated. Reduces blood filtration.

*Frequent Vomiting
 
 
Treatment:
 
*Medicine
 
*Surgery; requiring 10 glitterworld medicine and a doctor of medical skill 5 or above
 
 
 
===Flu===

Diseases are temporary and treatable ailments, that pass away after a certain amount of time or treatment.

Contract[edit]

Most diseases are contracted as part of an event. Your colony's biome determines how common diseases are, as well as how common each disease is. However, some diseases happen situationally, regardless of biome:

Note that diseases are not contagious in RimWorld. Disease does not ever spread between colonists, though disease events often simulate "outbreaks" by inflicting multiple colonists at the same time.

The drug penoxycyline protects against Malaria, Plague, and Sleeping sickness. The disease event still happens, but colonists will not be affected.

Summary[edit]

Humans and animals can get diseases. Most diseases uses the severity mechanic. As a disease progresses, its symptoms progressively get worse. If a fatal disease's severity reaches 1.0 (100%), then death occurs. Most diseases go from minor -> major -> extreme. How fast a disease progresses depends on the disease itself.

Diseases[edit]

Note: Base values of severity and immunity gain speed used in the table.
Treatment's reduction of severity depends on tend quality. 50% tend quality equals half the reduction.

    • Medicine and bed rest
  • Treatment[edit]

    Most diseases can be tended to, just like an injury or ailment, by a Doctor pawn and when the afflicted pawn is assigned to Patient themselves. Tend Quality is determined by a variety of factors, including the doctor's skill and the quality of Medicine used. Generally, higher quality tends reduce the total time until recovery, though mechanics vary. How often a disease can be tended depends on the disease itself.

    There are 3 types of diseases to tend to:

    • The disease will progress over time, and treatment slows down progression. Immunity is gained over time, dependent on Immunity Gain Speed and independent of tend quality. Once immune, the disease will slowly fade and the colonist will stop being a patient. This applies to most fatal diseases, including the flu, infection, and plague.
    • The disease does not progress. Treatment must reach a total tend quality (300%) before the disease is cured. For example, 4 tends at 80% quality would equal 320% total tend quality. Applies to gut worms and muscle parasites.
    • The disease progresses over time, and treatment slows and even prevents progression. The disease fades only after a certain time. Applies to lung rot, fibrous mechanites, sensory mechanites, and blood rot.Content added by the Royalty DLC

    Certain diseases have specialized cures. For example, infection in a non-vital part can be cured by amputating or replacing a limb, blood rot can be instantly cured with glitterworld medicine, and gut worms can be treated by replacing the stomach. In addition, a healer mech serum immediately cures any disease.

    Immunity gain[edit]

    Some diseases are a race between the increasing severity of the disease and the increasing immunity to it. This immunity gain is controlled by several factors:

    • Base immunity gain speed for the particular disease.
    • InfectionLuck, an uncontrollable generated value that adds randomness to the diseases progression. Each disease has a variance in Immunity gain speed of 20% up or down.
    • The Immunity Gain Speed stat of the patient

    Immunity Gain Speed is affected by the following:

    Note that these only apply to diseases with immunity mechanics. For example, you don't need to give a pawn with gut worms bedrest.

    Disease frequency[edit]

    Disease frequency by AI storyteller[edit]

    Disease frequency is controlled directly by the Disease frequency AI storyteller setting.

    This value can be changed in custom storyteller settings, but has the following default values by difficulty:

    Difficulty Disease interval multiplier
    Peaceful 3
    Community builder 2.5
    Adventure story 1.3
    Strive to survive 1.0
    Blood and dust 0.95
    Losing is fun 0.9
