Cholera scientific name

Vibrio cholerae is a bacterium that can make a toxin affecting the intestine. This can lead to sudden, watery diarrhoea and vomiting, with rapid loss of fluid and electrolytes. The scientific term identifies the organism; it does not describe how severe a particular person’s illness is. Severity is judged from hydration, circulation, alertness, urine output and the ability to drink.

Tell a healthcare professional about the frequency and appearance of [Diarrhoea](/symptoms/diarrhoea/), vomiting and any change in alertness. These details guide the urgency of care more directly than the terminology alone.

Use [Oral Rehydration Therapy](/treatments/acute-and-urgent-care/oral-rehydration-therapy/) as directed, taking small frequent sips when nausea is present. Prepare it with safe water and do not dilute it differently from the instructions. If drinking is impossible or dehydration is advanced, clinicians may give [IV Fluid Therapy](/treatments/acute-and-urgent-care/iv-fluid-therapy/). Avoid delaying assessment to search for a different home remedy.

Seek urgent care for severe thirst, faintness, confusion, very little urine, a rapid heartbeat, cold or clammy skin, persistent vomiting, or inability to drink. Watery diarrhoea with worsening weakness deserves prompt assessment even before all warning signs appear. Young children, older adults, pregnant people and those with chronic disease can need help sooner.

Ask whether the illness needs testing, how to monitor hydration at home, when to switch from oral to intravenous fluids, and what steps reduce spread through contaminated hands, food or water.
