Cholera-affected countries worldwide

Estimates of the World Health Organisation (W.H.O.) report 3 to 5 million people affected by cholera and 100 000 to 200 000 deaths each year worldwide.

Cholera epidemics are reemerging worldwide since the last decade, mainly due to:

Rapid urbanization of many cities in developing countries, where water and sanitation infrastructure are not financed by governments;
Profound environmental changes such as global warming, which play a role in the proliferation of the cholera bacteria in the environment (Source: Cholera and Climate change : a demonstrated relationship, Constantin de Magny G., Colwell R., 2009).
