Where is it most commonly found?

Cholera is mainly found in areas of poor hygiene and sanitation.

How are you likely to catch the disease?

Direct faecal-oral contamination or by consuming contaminated water or food.

Who needs to be vaccinated?

People at considerable risk; for example, if you’re working in humanitarian disaster and relief situations or if you’re travelling to an area that has a cholera epidemic (a widespread occurrence of an infectious disease in a community at a particular time).

How is the vaccination given?
