Treatment for cholera infection

Cholera can cause sudden, large-volume watery diarrhoea and vomiting. The main danger is rapid loss of fluid and electrolytes, which can lead to intense thirst, dry mouth, reduced urination, weakness, dizziness, confusion or collapse. A person can become seriously dehydrated while still having frequent diarrhoea, so waiting for symptoms to settle is unsafe.

Seek medical care promptly and begin oral rehydration therapy if you can drink and have been advised how to use it. Take frequent small sips, including after each loose stool, and mix the solution exactly as directed. Severe dehydration, ongoing vomiting or inability to drink may require IV fluid therapy in a healthcare setting. Clinicians may test the illness, monitor urine and vital signs, and prescribe an antibiotic in selected cases. Avoid relying on plain water alone or taking anti-diarrhoeal medicines without advice.

Go to urgent care for fainting, confusion, extreme weakness, very little urine, cold or clammy skin, persistent vomiting, blood in stool, or inability to drink. Children, older adults, pregnant people and anyone with another serious illness may deteriorate quickly and should be assessed early.

Ask how much oral rehydration solution to take, which signs show worsening dehydration, whether testing or antibiotics are needed, and how to reduce spread to household contacts.
