What is Cholera?

An acute intestinal infection caused by bacteria that is found in contaminated water or food. The onset is sudden with vomiting and as much as 10 litres of severe, painless diarrhoea a day. The danger lies in the risk of dehydration and shock. In the Netherlands, there is a cholera vaccine that is administered in liquid form and also provides protection against the E.coli (ETEC) bacteria. This is the most common type of bacteria that causes traveller's diarrhoea. Certain countries in Africa and Asia require proof of vaccination against cholera. This is a stamp that reads "cholera medically not indicated" and is valid for six months. Subsequently, a new stamp must be obtained when travelling to a country for which this is a requirement.
