What should you know about cholera organism?

Vibrio cholerae can live in contaminated water or food and enter the body when swallowed. In the intestine, certain strains produce a toxin that drives the movement of water and salts into the bowel. This can lead to large-volume watery [Diarrhoea](/symptoms/diarrhoea/) and vomiting. The immediate medical concern is the resulting loss of fluid and electrolytes, not simply the presence of the bacterium.

Arrange prompt medical assessment and begin a suitable oral rehydration solution if the person can swallow safely. Continue offering frequent sips while seeking care. A clinician may assess hydration and arrange testing. [Oral Rehydration Therapy](/treatments/acute-and-urgent-care/oral-rehydration-therapy/) replaces water and salts; [IV Fluid Therapy](/treatments/acute-and-urgent-care/iv-fluid-therapy/) may be required when dehydration is severe or oral intake fails. Handwashing and safe food handling help reduce transmission.

Seek emergency care for fainting, confusion, profound weakness, repeated vomiting, very little urine, cold or clammy skin, or inability to drink. Rapid fluid loss can worsen before the person recognises thirst. Young children, older adults, pregnant people, and people with chronic conditions need a low threshold for urgent evaluation.

Ask whether testing is needed, how the infection may have been acquired, which fluids to use, whether close contacts need advice, and which changes require immediate return.
