What should you know about cholera morbus?

Historical medical writing used “cholera morbus” for an acute gastrointestinal illness, and the wording may still appear in older records or searches. It is not a modern treatment plan and does not, by itself, tell you whether the illness is caused by Vibrio cholerae, another infection, contaminated food, or a non-infectious problem.

The practical issue is the pattern and severity of symptoms. Sudden watery diarrhoea and vomiting can drain water and electrolytes quickly, so the person’s hydration and general condition need attention. Use [Diarrhoea](/symptoms/diarrhoea/) for related symptom information.

Use a correctly prepared oral rehydration solution and offer frequent small sips when the person is able to drink. Keep food and drinking water hygienic, wash hands carefully, and avoid sharing towels or preparing food for others while infectious diarrhoea is possible. Medical advice is needed to clarify the cause and treatment.

If vomiting prevents drinking or dehydration is advanced, a healthcare team may use [IV Fluid Therapy](/treatments/acute-and-urgent-care/iv-fluid-therapy/). For someone who can drink, [Oral Rehydration Therapy](/treatments/acute-and-urgent-care/oral-rehydration-therapy/) can replace water and salts.

Seek emergency help for fainting, confusion, unusual drowsiness, severe dizziness, very little urine, inability to drink, or persistent vomiting. Arrange prompt assessment for repeated watery diarrhoea, worsening weakness, blood in stool, or illness in a baby, older adult, pregnant person, or someone with a chronic condition.

Ask whether the historical term matches your current symptoms, whether a stool assessment is needed, how much rehydration to give, and what changes mean you should return urgently.
