Colonists sometimes contract diseases. Diseases most often occur through random events that vary by biome and difficulty. Infections have a random chance of developing from an injury regardless of biome.

Effects

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.

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 critical 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. Progression of the disease is slowed depending on how good the treatment was.

Immunity: Colonists will gradually develop immunity to potentially fatal diseases, such as wound 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 100% before immunity does, 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 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 chronic diseases.

Non-fatal

These diseases cannot kill the colonist but can hamper effectiveness.

Gut Worms

Main article: Gut worms

Parasitic worms in the gut. They cause vomiting. They also consume the victim's food, which increases hunger.

— Description

Gut worms are a parasitic disease that infects the stomach, causing pain and nausea and doubling the host's hunger rate.

Stages

General

• Hunger Rate Factor: +100%
• Pain: +20%
• Vomiting (MTB of 1 day)
• −5 Sick mood, stacking with any mood effect from the pain.

Progression

Gut Worms do not increase in severity over time, nor are they cured over time. Direct treatment is the primary way to cure it.

Treatment

Gut Worms will be cured when the treatments performed on it reach a cumulative tend quality of 300%, thus it is important to maximize the Medical Tend Quality of the Doctor performing the tending and the quality of the medicine used. It takes 48 ingame hours (2 days, or 120,000 ticks (33.33 mins)) between each treatment. For example, the disease can be treated with 3 treatments at 100% quality, or 5 at 60%, or 1 at 130% plus 2 at 85%.

Other treatments

• Administer healer mech serum - instantly treats the disease
• Install a bionic stomach (or other stomach replacements)
• Use the medic cycle of the Biosculpter pod
