Haiti's cholera outbreak

In October 2010, Haiti was hit by an outbreak of cholera, the first in recent history of the impoverished Caribbean nation. Nepalese peacekeepers belonging to the international MINUSTAH mission were blamed for introducing the deadly disease, but for many years the UN refused to accept any responsability. More than 10,000 Haitians have died from cholera, and thousands more were infected. The UN finally apologised to the Haitian people in December 2016.
