Cholera vaccination protects against a bacterial infection that causes severe diarrhoea and dehydration. It is recommended for a small number of travellers visiting remote areas with limited access to medical care, or those working in disaster relief. A pre-travel consultation reviews your itinerary to confirm whether cholera vaccination is advised.
What Is Cholera?
Cholera is a bacterial infection usually spread through contaminated water or food, particularly in areas without a clean water supply. It causes severe watery diarrhoea and vomiting, which can lead to rapid dehydration if not treated promptly.
Who Should Consider Vaccination?
Most travellers do not need the cholera vaccine, as the overall risk is low. It is usually recommended only for those travelling to areas where cholera is common and who will be visiting remote places without access to medical care, or for aid and disaster relief workers heading to an area where a cholera outbreak is likely.
Vaccination Schedule
The cholera vaccine is given as an oral drink, usually as two doses taken one to six weeks apart for adults. Both doses should be completed at least a week before travel, and protection can last for up to two years.
Food and Water Precautions
Vaccination reduces but does not eliminate the risk of cholera. Following safe food and water practices, such as drinking only bottled or boiled water, avoiding ice and uncooked food, and washing hands regularly, remains essential even after vaccination.
