UN peacekeepers brought cholera to Haiti
In October 2010, months after the earthquake, cholera appeared in Haiti, where it had not been recorded in living memory. It was traced to a UN peacekeeping base near Mirebalais, where Nepalese troops' sewage leaked into a tributary of the Artibonite River. The outbreak killed thousands, and the UN spent years denying responsibility, so a foreign stabilization force became the source of a new national epidemic.
