Emotional demonstrations (emo-demos) are used in behaviour-centred design to trigger behaviour changes, such as handwashing with soap, by creating disgust and shame. This eight-page case study presents the emo-demo for triggering behaviour changes at vaccination centres, which were found to be ideal places to raise awareness of the importance of washing hands with soap among pregnant women, mothers and caregivers.

Diarrhoeal disease is the second leading cause of death in children under five years old. Handwashing with soap can reduce the risk of diarrhoeal disease by up to 48% but knowledge of its importance for disease prevention is not always reflected in practice. Oxfam, Unilever's Lifebuoy soap and Unilever's Chief Sustainability Office have developed Mum's Magic Hands, an interactive approach based on storytelling which uses field tested, emotional and health motivators to promote effective hand washing in communities affected by emergencies.

Poor nutrition and exposure to faecal contamination are associated with diarrhoea and growth faltering, both of which have long-term consequences for child health. This trial aimed to assess whether water, sanitation, handwashing, and nutrition interventions reduced diarrhoea or growth faltering.
