What should you know about cholera type?

Cholera is caused by certain strains of Vibrio cholerae, usually acquired through contaminated water or food. The bacteria produce a toxin that makes the intestine release large amounts of water and salts. Some infected people have mild symptoms or none, while others develop abrupt, frequent watery stools and vomiting. The infection is not identified by stool appearance alone; a clinician may decide whether testing and public-health advice are needed.

If cholera is possible, start oral rehydration solution as directed and arrange prompt medical assessment. Take small sips often if nausea is present. Use safe water for drinking, cooking, brushing teeth, and preparing rehydration solution. Wash hands thoroughly after toilet use and before handling food, clean shared surfaces, and avoid preparing meals for other people while ill. Do not take leftover antibiotics or anti-diarrhoeal medicine without professional advice.

Urgent help is needed for fainting, confusion, unusual sleepiness, severe thirst, a dry mouth, little or no urine, cold skin, persistent vomiting, or diarrhoea that is too frequent to replace by drinking. Seek early advice for a young child, older adult, pregnancy, or a person with kidney, heart, or other long-term disease. A person can become dehydrated even when there is no fever.

Ask how cholera is confirmed, how to protect household members, which fluids are appropriate, and what symptoms should trigger immediate transfer to hospital.
