What should you know about cholera sickness?

The infection is linked to swallowing Vibrio cholerae bacteria, usually through contaminated water or food. Some people have mild illness or no noticeable symptoms, while others develop frequent, watery stools and vomiting. The main danger is the speed at which the body loses water and electrolytes. Thirst, dry mouth, weakness, dizziness, reduced urination, sunken eyes, or unusual sleepiness can signal dehydration. Read more about [Diarrhoea](/symptoms/diarrhoea/) and tell a clinician about recent travel, unsafe water exposure, or other unwell household members.

Start an oral rehydration solution as soon as possible, taking frequent small sips, especially after each loose stool or episode of vomiting. Follow the product instructions for mixing; do not dilute it with extra water or replace it with very sugary drinks. Continue breastfeeding and offer suitable food when tolerated. A clinician may assess stool symptoms, hydration, kidney function, and the need for prescribed treatment. Severe dehydration may require [IV Fluid Therapy](/treatments/acute-and-urgent-care/iv-fluid-therapy/), while milder fluid loss may be managed with [Oral Rehydration Therapy](/treatments/acute-and-urgent-care/oral-rehydration-therapy/). Wash hands with soap and water and keep food preparation separate from toileting.

Seek urgent medical help for repeated watery stools, persistent vomiting, faintness, confusion, very little urine, inability to drink, marked weakness, or a cold and clammy appearance. A child, older adult, pregnant person, or someone with kidney, heart, or other serious illness can become dehydrated quickly. Contact a healthcare service promptly if cholera is suspected after exposure or travel, even if symptoms seem manageable, because fluid needs can change rapidly.

Could this illness be cholera or another cause of watery diarrhoea? How much oral rehydration solution should I take? Which dehydration signs mean I should return immediately? Do household members need assessment or specific hygiene advice?
