Third cholera pandemic

Cholera is an intestinal infection that can spread when food or water is contaminated with the bacterium that causes it. The illness may produce sudden watery diarrhoea and vomiting. The main immediate danger is loss of water and salts, which can lead to dehydration, shock, and death without prompt treatment. Historical cholera pandemics exposed the connection between sanitation, safe water, waste disposal, and community health.

For suspected cholera today, begin oral rehydration solution if the person is awake and able to drink, following the product instructions. Continue offering small, frequent amounts and seek medical care promptly. Severe dehydration may require IV fluid therapy. Handwashing with soap, safe drinking water, cooked food, and careful disposal of stools reduce spread. Do not rely on plain water alone when diarrhoea is substantial because lost salts also need replacement.

Seek urgent medical help for profuse watery diarrhoea, repeated vomiting, very little urine, extreme thirst, dizziness, confusion, unusual sleepiness, a fast heartbeat, or cold hands and feet. Young children, older adults, pregnant people, and anyone with another serious illness can deteriorate quickly. Keep drinking oral rehydration solution while arranging care if swallowing is safe, and tell clinicians about travel, unsafe water, or other affected household members.

Could this diarrhoea require testing or treatment? How should oral rehydration solution be prepared and given? What signs of dehydration should my household watch for, and should close contacts receive public-health advice?
