What should you know about infection of cholera?

Cholera is an intestinal infection that can produce frequent, very watery stools and vomiting. The main danger is dehydration: thirst, dry mouth, dizziness, reduced urination, weakness, drowsiness, and a fast heartbeat may develop as fluid leaves the body. The stool may look pale and cloudy, but appearance alone cannot confirm cholera. Testing and clinical assessment help distinguish it from other causes of [Diarrhoea](/symptoms/diarrhoea/).

Start an appropriate oral rehydration solution as soon as possible, taking frequent sips and continuing after each loose stool if able. Keep drinking even if vomiting occurs, using small amounts repeatedly. Seek medical care promptly for testing, monitoring, and treatment. Severe dehydration may require [IV Fluid Therapy](/treatments/acute-and-urgent-care/iv-fluid-therapy/), while [Oral Rehydration Therapy](/treatments/acute-and-urgent-care/oral-rehydration-therapy/) can replace water and salts when drinking is possible. Wash hands carefully and avoid preparing food for others while unwell.

Seek emergency care for fainting, confusion, severe weakness, inability to drink, very little urine, cold or clammy skin, or repeated vomiting. Urgent assessment is also needed when watery diarrhoea is frequent, symptoms follow unsafe water or food exposure, or a young child, older adult, or medically fragile person is affected.

Ask which rehydration solution to use, how to monitor urine and alertness, whether testing is needed, and which hygiene steps protect people sharing your home.
