OXFAM – Hygiene promotion: determining what works, 2012. Humanitarian field studies | Cholera response in Haiti
When a massive earthquake struck Haiti in January 2010, followed by a cholera epidemic that broke out in October of that year, Oxfam rushed assistance—clean water, sanitation, and hygiene materials and information—to hard-hit areas to protect public health.
Hygiene promotion is arguably the most important intervention in a cholera epidemic: the route of cholera transmission is fecal-oral, and contaminated hands are often the principal vector. So Oxfam engages in a wide range of hygiene-promotion activities to encourage washing hands—specifically, washing hands with soap at key moments, such as before eating and after defecation.
But which of our interventions have been the most effective, and why? Is it more important to put resources into hygiene-themed theater productions or radio call-in shows? There is little hard evidence to suggest that—in Haiti or in emergencies anywhere—one hygiene-promotion activity works better than another. But lives, not to mention valuable resources, may depend on the answer, so in the spring of 2011, Oxfam engaged Eawag, the Swiss Federal Institute of Aquatic Science and Technology, to study the effectiveness of our hygiene-promotion activities in Haiti.
