Haiti has been battling a cholera outbreak since 2010, and it’s still killing people. Why has no one been able to stop the spread of the disease?

In early February, when Jenniflore Abelard arrived at her parents’ house high in the hills of Port-au-Prince, Haiti, her father Johnson was home. (Some names have been changed to protect the privacy of patients and family members.) He was lying in the yard, under a tree, vomiting. When Jenniflore spoke to him, his responses, between retches, sounded strange: “nasal, like his voice was coming out of his nose.” He talked “like a zombie.” This is a powerful image to use in Haiti, where voodoo is practiced and where the supernatural doesn’t seem as far-fetched as it might elsewhere. Her father’s eyes were sunk back into his head. She was shocked, but she knew what this was, because she has lived through the past five years in Haiti. She has lived through the time of kolera.

On October 18, 2010, Cuban medical brigades working in the areas around the town of Mirebalais in Haiti reported a worrying increase in patients with acute, watery diarrhea and vomiting. There had been 61 cases the previous week, and on October 18 alone there were 28 new admissions and two deaths.
