According to World Health Organisation, Cholera is an acute diarrhoeal disease that can kill within hours if left untreated.
It is a disease affecting people with inadequate access to safe water and basic sanitation.
Conflict, unplanned urbanization and climate change all increase the risk of cholera.
Researchers have estimated that each year, there are 1.3 to 4.0 million cases of cholera, and 21 000 to 143 000 deaths worldwide due to cholera.
Most of those infected have no or mild symptoms and can be successfully treated with oral rehydration solution.
