In October 2010, cholera broke out in the Centre Department of Haiti. The country had not seen a single case in over a century. This meant that when Haitians began vomiting and having diarrhea, most of the Haitians alive had never seen its symptoms before.
Four years on, the water-borne disease continues to plague Haiti, and has since spread to at least ten other countries, including the Mexico, Cuba, Germany and Venezuela.
Every summer, cholera treatment centers in Haiti are closed down as low rainfall means fewer cases of cholera. But as the monsoon season returns every October, cholera treatment centers fail to open in time to treat the sudden increase in patients and Haitians continue to die.
And though the mortality rate has fallen from almost 2.4 per cent to just 1.22 per cent, it remains above the "acceptable" rate of 1 per cent.
