On 19 October 2010, ten months after a devastating earthquake hit Haiti, the Haitian Ministry of Public Health and Population (MSPP) was notified of a sudden surge in patients suffering from watery diarrhea and dehydration. Two days later, the Haiti National Public Health Laboratory identified the culprit: Vibrio cholerae. On 22 October, officials announced the first cholera outbreak in Haiti in more than a century.
