What should you know about cholera and diarrhea?

Cholera is an intestinal bacterial infection, while diarrhoea is a symptom involving frequent loose or watery stools. Cholera can cause especially rapid loss of water and salts, sometimes with vomiting. However, diarrhoea can also result from other infections, food irritation, medicines, or longer-term bowel problems. The symptom alone cannot identify cholera. Exposure to unsafe water or food, sudden onset, the amount of fluid lost, and the person’s general condition help guide medical assessment.

Use Oral Rehydration Therapy when the person is alert and able to drink. Offer small, frequent sips and continue safe fluids; restart gently after vomiting settles. Keep food simple and tolerated, and wash hands thoroughly after toileting and before meals. Do not share towels or prepare food for others while unwell. Avoid taking anti-diarrhoeal medicine or antibiotics without advice, particularly when there is blood, fever, or severe pain. IV Fluid Therapy may be needed when drinking cannot replace losses.

Seek urgent care when diarrhoea is accompanied by fainting, confusion, severe weakness, very little urine, repeated vomiting, or inability to drink. Prompt assessment is also needed for blood in stool, severe abdominal pain, or rapidly worsening symptoms. Children, older adults, pregnant people, and those with chronic illness can become dehydrated sooner. Call emergency services for collapse, difficulty waking, or a major change in alertness.

Ask what cause is most plausible, whether testing is needed, how to measure hydration at home, and which symptoms should prompt hospital care. Describe stool changes, vomiting, fluid intake, urination, travel, and possible food or water exposure.
