Quick answer
Pond, stream and lake water can carry the pathogen.
Quick answer
First job: stop repeating the exposure. Pond, stream and lake water can carry the pathogen, and freshly spawned bottles and canteens can already contain contaminated water.
The strongest pattern is unsafe-water exposure followed by Fever and forehead wiping, blur, rapid dehydration and vomiting when too much is consumed at once.
Cholera sharply reduces effective stomach capacity, so use very small sips and bites, pause, let the stomach clear, then repeat.
One Tetracycline effect lasts about five minutes; taking duplicate doses at the same moment does not make the medicine stronger.
The sickness icon can disappear early: watch the medication effect and symptoms instead of returning to the suspect food or water.
Guide details
Typical sources: unsafe water, contaminated found bottles, food or drink touched by an infected survivor, blood transfusion from a sick survivor
Treatment routes: Tetracycline, or Multivitamins as a supported route — several sequential treatment windows may be needed
Chlorine Tablets are prevention for questionable ordinary water, not the treatment for an established infection
Reinfection prevention: clean or replace contaminated containers and food, and do not share partly consumed items with a sick teammate
Cholera is a water-route problem before it is a pill problem
The strongest Cholera pattern is unsafe-water exposure followed by Fever/forehead wiping, blur, rapid dehydration and vomiting when the survivor tries to consume too much at once. Vomiting by itself is not enough; Salmonellosis, Food Poisoning, gas exposure and simple stomach overfilling can also cause it.
Why large drinks make the problem look worse
Cholera sharply reduces effective stomach capacity. That is why a sick survivor can vomit after a drink that would be harmless when healthy. Each vomiting episode throws away Water and Energy you are trying to restore. The field rule is simple: use very small sips and bites, pause, let the stomach clear, then repeat.
Treatment: Tetracycline, Multivitamins and stability
• Stop using the suspected water/food item and move to a clean source.
• Take one Tetracycline dose or use Multivitamins as a supported treatment route. The same medicine does not become stronger by taking duplicate doses simultaneously.
• Keep Heat Comfort safe and restore Water/Energy using tiny controlled amounts.
• When the current medication effect expires, reassess symptoms before using the next needed dose.
• Clean or replace contaminated containers/food so the recovered survivor does not immediately reinfect themself.
The current treatment effect lasts a Tetracycline effect duration of about five minutes. Cholera may require several sequential treatment windows depending on progression. Exact pill counts vary with how advanced the disease is; use the symptoms and medication effect rather than assuming one tablet must always be enough.
The sickness icon can disappear early
Current Cholera documentation warns that the sickness icon may vanish before the infection is fully cleared. That is a reason to watch the medication effect and symptoms instead of immediately returning to the suspect food or water. Do not use the disappearance of one HUD icon as permission to repeat the original exposure.
Prevent reinfection: the container matters
Common Cholera mistakes
• Drinking a full container quickly because the Water icon is red.
• Taking Charcoal because “vomiting means food poisoning.”
• Using Tetracycline but continuing to drink from the same contaminated bottle.
• Treating Chlorine Tablets as medicine for an infection already inside the character.
• Sharing partly consumed water/food with a sick teammate and creating a reinfection loop.
• Assuming one disappearing sickness icon proves every pathogen has cleared.
Situation | Safe response
Water Pump / clean Water Spring | Drink or refill normally; wash bloody hands before direct drinking.
Found bottle/canteen with existing water | Safest: empty and refill at a clean source; otherwise purify correctly.
Pond / stream / lake | Treat before routine drinking: chlorine or a valid boiling setup.
Food/water partly consumed by a sick survivor | Do not share it; replace or purify water as appropriate.
Recovered survivor still carrying the suspect drink | Remove the contamination before using it again; reinfection is possible.
FAQ
Does vomiting alone prove Cholera?
No. Vomiting by itself is not enough: Salmonellosis, Food Poisoning, gas exposure and simple stomach overfilling can also cause it. Judge the exposure history together with the symptom pattern.
Why does drinking more make it worse?
Cholera sharply reduces effective stomach capacity, so a drink that would be harmless when healthy can trigger vomiting — and each episode throws away Water and Energy you are trying to restore. Small sips and bites, with pauses, are easier to keep down.
Can Chlorine Tablets cure Cholera?
No. Chlorine Tablets are prevention for questionable ordinary water, not medicine for an infection already inside the character. Use Tetracycline or Multivitamins as the treatment route instead.
I feel better — can I drink the old water again?
No. The sickness icon can vanish before the infection is fully cleared, and a recovered survivor carrying the suspect drink can reinfect themself. Clean or replace the contaminated container and food first.
