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 8.333 days from discovery.
Good treatment can slow the disease to the point where it takes up to 20 days to kill.

It takes around 8.47 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.

Progression

When not immune, severity increases by 0.12 per day.
When immune, severity decreases by 0.176 per day.
Immunity increases by 0.11 per day when sick.
Treatment slows progression by a maximum of 0.07 per day.
- This means the disease will progress by 0.05 per day at this rate.

'Waking up' from Sleeping Sickness

Despite Sleeping Sickness' uniqueness in the respect that it's slower 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.

Unlike other diseases, treatment is administered once every 32 hours (as opposed to 12).

Normal people

Technically people with normal immunity do not need to be treated, as long as they are constantly rested, but this is not recommended.

For those with a base immunity gain rate of 92.7% or less, sleeping sickness cannot be survived without treatment, even if the pawn is constantly resting in a bed.

Version history

In 1.0 treatment above 53% quality used to be able to cause the disease to regress; if applied early enough, it could cause the disease to vanish entirely.

In 1.1, disease progression was significantly accelerated, and treatment no longer causes disease to regress. In addition, in a minor update of 1.1, immunity gain was boosted, such that colonists can survive without treatment as long as they remain in bed.
