Cholera

Untreated water from lakes, ponds and rivers, a contaminated found bottle, or sharing a drink with someone who has it.

Shows up

~20–30 min

After drinking contaminated water.

Heals by itself

Practically never

Only with an immune system above ~95 %.

Cure

Tetracycline

1 pill early on, ~4 at its peak.

Kills by

Thirst & hunger

Every vomit costs 450 water and 310 food.

Cholera germs come from untreated natural water. The game counts them in your body as agents, up to 1000: they multiply slowly (0.15 per second) unless your immune system is above ~95 % or multivitamins are working. You get sick from 250 agents, ~20–30 min after drinking — and the longer you wait, the more pills it takes.

Stages

How the disease runs in the game, stage by stage: when it starts, what it does, and whether it still heals.

  1. Incubation

    only with medicine

    1–249 agents

    Nothing you can notice yet; the agents grow by 0.15 per second.

    Your body kills them (0.45 per second) only with an immune system above ~95 % or with multivitamins. Tetracycline already works now.

    ~28 min after a tiny dose, ~22 min after 50 agents.

  2. Cholera

    only with medicine

    from 250 agents (of 1000); ends at 50

    Symptoms

    • Vomiting
    • Getting thirsty unusually fast
    • Feeling hot
    • Blurry vision
    • Thermometer shows 38.5 °C or more
    • Sick icon in the status bar

    You vomit once when it starts, then often whenever there is food or water in your stomach. Every vomit costs 450 water and 310 food, empties 65 % of your stomach and leaves your stamina weak for 30 s. On top: thirst, fever (an extra 0.2 water per second, blurred vision, 38.5–39 °C on a thermometer) and the sick icon.

    Not by itself: your body kills cholera only with an immune system above ~95 % or with multivitamins. Otherwise it keeps growing until it peaks, ~83 min after it started.

    Deadly: Indirectly, through thirst and hunger — no fixed time.

How to get rid of it

Take tetracycline and keep taking a pill whenever the last one has worn off, until the vomiting stops (up to three or four pills). Multivitamins help. Drink clean water.

How to avoid it

Drink from wells and pumps; boil or chlorinate all other water, found bottles included.

Good to know

  • Filling a bottle at a pond, lake or river gives it cholera one time in ten.
  • Boiling, chlorine tablets or chelating tablets make water safe from cholera.

Not sure it is this?

The doctor asks what you notice on your character and names the disease and its stage.
