Cholera, which had not been documented in Haiti in almost 100 years prior to the 2010 outbreak (ten months after the earthquake), is an infection that causes severe diarrhea that can lead to dehydration and death if untreated. Despite an important decrease in the number of cholera cases, since the beginning of the outbreak there have been approximately 700,000 cases, of which 8,500 have died. This value exceeds the number of cases in Africa, a continent with over 100 times the population of Haiti. In 2013, cholera cases in Haiti amounted to almost 47% of worldwide cases.
