Cholera is an infectious disease in DayZ Standalone. It is a bacterial infection spread through drinking unsafe and unclean water


Invasiveness Average How quickly a disease grows and spreads in an infected host.
Infectiousness Very Low The ease at which a disease can spread from one Survivor to another.
Resistance None A disease's resistance to antibiotics.
Potency Average A disease's resistance and ability to fight the host's immune system.


Survivors in DayZ Standalone can become infected with the bacteria Vibrio cholerae by:

  1. Drinking from unclean or un-purified water sources such as Ponds, Streams and Lakes.
  2. Drinking from freshly spawned Plastic Bottles and Canteens which have an initial 50/50 chance of carrying the pathogen.

The Immune System mechanic provides a passive resistance to being initially infected but if the survivor's is weak enough when engaging in any of the above activities; this can result in infection anyway.


Vomiting is the most common symptom of Cholera. This can lead to severe hunger and dehydration quickly without medication.

Even when not vomiting initially: the player's hydration level will also deplete quicker with slower running causing up to 3 arrows depletion when sprinting when healthy and 2 arrows depletion whilst standing still.

The player's running speed is also slowed eventually with audible groaning when Hydration levels reach Yellow and vomiting becomes more frequent.

Note: The disease is not automatically a death sentence if controlled until medication can be found or the Immune System defeats it; but a move speed penalty coupled with uncontrollable, disabling bouts of vomiting depleting a player's Hydration and Food levels can quickly burn through food and water resources or make the player visible and vulnerable to other players, hostile animals and the environment at inopportune times.


Purifying water taken in containers from non-Water Pump sources with Chlorine Tablets or boiling it in a Cooking Pot before consumption.


  • In the event of infection: taking Tetracycline Pills will help a survivor fight off the infection. The survivor can also fight off the infection naturally through the Immune System mechanic but this process will take longer.
    • In either case: it is recommended that an afflicted survivor consume food and water to offset the energy loss from vomiting, but only in small amounts at a time.
      • If a survivor with Cholera eats or drinks too much at one time; they will begin vomiting again immediately.
