Sleeping sickness

Sleeping sickness is a parasitic disease that can only be caught in the tropics, either Rainforests or Swamps. Sleeping Sickness takes a very long time to develop and also gain immunity to. Those affected by Sleeping Sickness will be in bed for a long time.

General symptoms include slightly impaired consciousness and manipulation, a small amount of pain, and eventually occasional vomiting. Advanced symptoms include a small to moderate amount of pain, more adversely affected consciousness and manipulation, more frequent vomiting, eventually a loss of consciousness, and finally, death.

If Sleeping Sickness is left untreated, it will kill the affected colonist in around 17.035 days from discovery.
Good treatment can slow the disease to the point where it begins to regress; if treated at the very beginning, the disease will vanish quickly.

It takes around 18.52 days to develop immunity to sleeping sickness, assuming the patient is rested in an ordinary bed for the whole time and under the age of 40.

Stages

Minor (Initial) - Severity: 0 - 0.4374

  • +2% Pain
  • -2% Consciousness
  • -2% Manipulation

Minor (Advanced) - Severity: 0.4375 - 0.624

  • +3% Pain
  • -4% Consciousness
  • -4% Manipulation

Major - Severity: 0.625 - 0.874

  • Vomiting every 3.5 days (84 hours) on average
  • +5% Pain
  • -15% Consciousness
  • -6% Manipulation

Extreme (Initial) - Severity: 0.875 - 0.9374

  • Vomiting every 1.75 days (42 hours) on average
  • +10% Pain
  • -20% Consciousness
  • -20% Manipulation

Extreme (Advanced) - Severity: 0.9375 - 1

  • Vomiting every day (24 hours) on average
  • Maximum 10% Consciousness
  • +15% Pain
  • -20% Manipulation
  • Death

Progression

  • When not immune, severity increases by 0.0587 per day.
  • When immune, severity decreases by 0.176 per day.
  • Immunity increases by 0.0449 per day when sick.
  • Treatment slows progression by a maximum of 0.1125 per day.
    • This means the disease will regress by 0.0538 per day at this rate.

'Waking up' from Sleeping Sickness

Despite Sleeping Sickness' uniqueness in the respect that it's very slow to progress and conquer, it's not as difficult to successfully treat compared to other diseases such as malaria and the plague. However, you should still follow standard protocols and ensure that patients of Sleeping Sickness are rested at all times, well-fed, and promptly treated when they need to be treated.

Like Malaria and the Plague, Sleeping Sickness can be prevented, but not treated, by Penoxycyline.

Normal people

You will need at least 10% average treatment quality in order to sufficiently slow down Sleeping Sickness' progress to the point where it doesn't kill the patient.

Disease regression

Above 53% treatment quality, the disease begins to regress. This means that even pawns with non-functioning immune systems can survive the illness, as long as you administer good enough treatment.
