What should you know about cholera in pigs?

The word cholera can be used loosely for severe intestinal illness in animals, while several pig diseases can cause diarrhoea, fever, weakness, vomiting or sudden death. A veterinarian must distinguish infection, poisoning, feed problems and other causes. Some diseases spread rapidly through a herd and require official notification or movement controls.

Fluid loss is especially concerning when pigs stop drinking, become weak or remain apart from the group. Examination, samples and herd history help determine the safest response. Human cholera treatment should never be given to pigs without veterinary direction.

Separate affected pigs if this can be done safely, restrict movement between pens, and call a veterinarian or animal-health authority promptly. Record new illness, deaths, feed changes, water access and recent animal movements. Use dedicated boots and equipment, clean contaminated areas, and follow instructions for disposal of waste and carcasses.

Keep clean water available, but do not force fluids into a collapsed or struggling animal. A veterinarian may recommend oral or IV Fluid Therapy, testing, supportive care or a specific treatment. [IV Fluid Therapy](/treatments/acute-and-urgent-care/iv-fluid-therapy/) is performed under professional supervision, not improvised on a farm.

Seek immediate veterinary help for sudden deaths, multiple sick pigs, bloody diarrhoea, high fever, severe weakness, collapse, breathing difficulty or rapidly worsening illness. Do not transport affected animals or sell meat from a suspect group until the responsible veterinarian or authority gives instructions.

People handling sick pigs should wear suitable protective clothing, wash hands and avoid carrying contaminated tools between pens. Human [Diarrhoea](/symptoms/diarrhoea/) after contact with animals or waste needs medical advice and a clear exposure history.

Ask which diseases must be ruled out, whether samples are needed, how to isolate the group, what cleaning method is suitable, whether movement must stop, and how to provide water and feed safely.
