Colonists sometimes contract diseases. These can occur through random events that vary by biome and difficulty (except for infections, which have a random chance of developing from an injury).

Effects

Diseases cause infected colonists to suffer symptoms, which can vary from diseases to disease. Diseases progress through stages of intensity until either the colonist develops 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.

Treatment

At regular intervals, a resting colonist can be treated by a doctor. This slows the progression of symptoms, and for most diseases it is very important to treat the colonist as often as possible. You cannot give a new treatment until the last one has expired, 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 skill and the quality of medicine used.

Immunity: Colonists will gradually develop immunity to some diseases, such as infections or plague. When immunity reaches 100%, the symptoms will not immediately disappear, but the colonist is safe and no longer needs any treatment. If the disease symptoms progress past "extreme" before immunity reaches 100%, the colonist will 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 more 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 (eg. being untreated or gets worse).
  • Treatment - some illnesses are treatable with medicine, but not all diseases are treatable.

Flu

Main article: flu

Plague

General Symptoms:

  • Impaired consciousness
  • Impaired manipulation

Advanced Symptoms:

  • Impaired consciousness
  • Impaired manipulation
  • Impaired breathing
  • Loss of consciousness

Treatment:

  • Treated with medicine
  • Treatment duration: 30,000 ticks (8.33 mins)

Malaria

Easier to contract in the jungle.

General Symptoms:

  • Impaired consciousness
  • Impaired blood filtration

Advanced Symptoms:

  • Impaired consciousness
  • Loss of consciousness

Treatment:

  • Treated with medicine
  • Treatment duration: 30,000 ticks (8.33 mins)

Infection

Untreated wounds may get infected, causing a colonist to be mildly sick for a while. However, untreated infections can be fatal.

General Symptoms:

  • Pain

Advanced Symptoms:

  • Impaired consciousness
  • Impaired breathing
  • Unconsciousness

Treatment:

  • Treated with medicine
  • Treatment duration: 30,000 ticks (8.33 mins)
  • Can also be treated by amputating the affected body part

Sleeping Sickness

A parasitic disease carried by insects in the jungle biome.

It's notable that sleeping sickness takes a very long time to recover from.

General Symptoms:

  • Impaired consciousness
  • Impaired manipulation

Advanced Symptoms:

  • Loss of consciousness

Treatment:

  • Treated with medicine
  • Treatment duration: 80,000 ticks (22.22 mins)

Gut Worms

A parasitic disease which doubles that rate at which colonists become hungry.

Can be contracted in the following biomes: arid shrubland, desert, extreme desert, boreal forest, tundra, temperate forest, and tropical rainforest.

General Symptoms:

  • Increaser hunger rate (200% of base)
  • Increased vomit rate (to average once per day)

Advanced Symptoms:

  • None

Treatment:

  • Treated with medicine
  • Treatment duration: 120,000 ticks (33.33 mins)
  • Treatment count: 5

Muscle Parasites

A parasitic disease hampering the muscles.

General Symptoms:

  • Impaired manipulation (-30%)
  • Impaired movement speed (-30%)

Advanced Symptoms:

  • None

Treatment:

  • Treated with medicine
  • Treatment duration: 120,000 ticks (33.33 mins)
  • Treatment count: 5

Fibrous Mechanites

A Mechanoid disease which brings mild pain in early stages but boosts several attributes.

General Symptoms:

  • Tiredness (*170%)
  • Mild pain (+0.2)
  • Improved manipulation (+50%)
  • Improved movement speed (+50%)
  • Improved blood pumping (+50%)

Advanced Symptoms:

  • Intense pain (+0.6)
  • No additional stat boosts over early stages

Treatment:

  • Treated with or without medicine, though medicine speeds up recovery
  • Treatment duration: 120,000 ticks (33.33 mins)
  • Can disappear without treatment as early as 900,000 ticks (250 mins)
  • Can last without treatment as long as 1,800,000 ticks (500 mins)

Sensory Mechanites
