What should you know about cholera today?

The main danger is loss of water and salts rather than the bowel symptoms alone. Dehydration may cause a dry mouth, reduced urination, dizziness, unusual sleepiness, a fast heartbeat, or difficulty staying alert. Cholera can occur without fever, so the absence of fever does not rule it out. A clinician may assess symptoms, hydration, travel or outbreak exposure, and may arrange testing.

Start an oral rehydration solution if diarrhoea or vomiting is present, using the product instructions and small frequent sips. Continue breastfeeding when relevant and use safe drinking water. Do not delay medical assessment while trying home fluids. Severe dehydration may require IV fluid therapy, and a clinician may prescribe other treatment according to the illness and local guidance. Wash hands with soap and water after using the toilet and before preparing food.

Seek urgent medical care for repeated watery stools, inability to drink, persistent vomiting, faintness, confusion, very little urine, marked weakness, or signs of dehydration. Get help promptly after possible exposure if symptoms begin, even when the illness seems mild. Tell the healthcare team about recent travel, unsafe water or food exposure, and anyone else who is ill.

Ask which rehydration fluid is suitable, how to monitor urine and alertness, whether testing is needed, and which foods or medicines to avoid. If travel is planned, ask about destination-specific prevention advice and whether vaccination is appropriate for your itinerary.
