How common is diarrhoea in cholera?

Cholera is an infection that can cause sudden, frequent watery stools. The main immediate concern is fluid loss: the body can lose water and salts quickly, which may lead to thirst, dry mouth, weakness, dizziness, reduced urination, or fainting. Vomiting and abdominal cramps can occur too. Many other infections, foods, medicines, and digestive conditions can also cause loose stools, so the symptom alone cannot confirm cholera.

Begin replacing fluids as soon as possible. Take frequent small sips of safe water or an oral rehydration solution if available; this is especially useful if nausea makes larger drinks difficult. Continue feeding babies and children as usual where possible. Wash hands carefully after using the toilet and before preparing food, and avoid preparing food for others while unwell.

Seek urgent medical care for signs of dehydration, repeated vomiting that prevents drinking, confusion, fainting, marked weakness, or very little urine. Young children, older adults, pregnant people, and anyone with a long-term medical condition may become unwell more quickly. Get prompt advice if severe watery diarrhoea follows travel, exposure to unsafe water, or contact with someone known to have cholera.

Tell the clinician when the diarrhoea began, how often it is happening, whether there is vomiting or fever, recent travel, water and food exposures, medicines, and whether anyone close to you is unwell. Ask whether you need testing, specific treatment, or advice about preventing spread at home.
