2010 Haiti Cholera Epidemic: Mortality and Lessons Learned

The 2010 Haiti cholera outbreak, introduced by UN peacekeepers from Nepal, caused 820,000+ cases and 9,792 confirmed deaths (WHO, 2018 final report; estimates up to 10,000+).

Epidemiology

  • Index case: October 2010, Artibonite River contamination.
  • Rapid spread via inadequate sanitation, lack of clean water, displaced populations post-earthquake.
  • Peak incidence: 2011; endemic transmission continued for years.

Response & Legacy

  • Oral cholera vaccine (Shanchol/Euvichol) deployed in targeted campaigns from 2013.
  • Water, sanitation, hygiene (WASH) infrastructure investment remains incomplete.
  • UN acknowledged role in 2016; $400M cholera elimination plan launched.

Key Lesson

Cholera control requires safe water + sanitation + vaccination + surveillance—not just treatment.
