Cholera is a diarrhoeal disease caused by a bacterium called Vibrio cholerae. It is able to cause large outbreaks and epidemics. It causes gastro symptoms, mostly diarrhoea and vomiting which can lead to death in severe cases if not treated in time. Cholera can range from asymptomatic, to mild, moderate and severe cases.
Cholera outbreaks usually occur in the developing world and are associated with poor water, sanitation and hygiene infrastructures.
