Making Germs Visible - Assessing the Impact of a School-Based, Low-Cost Intervention on Hand Hygiene Knowledge, Attitude and Practice of Children in Rural India.

Handwashing with soap at critical moments is one of the most important factors in controlling the spread of germs and preventing the spread of infection. The objective of this study was to determine the effectiveness of a low-cost, school-based intervention that simulated germs and their spread on hand hygiene knowledge, attitude and practice of primary school children. Five hundred and sixty-two students from 28 rural schools were enrolled in this pre-posttest study. Endline data was collected 4 weeks after conducting the intervention at baseline. The mean scores for knowledge, attitude and practice improved significantly after the intervention ( p  < .05). Significant positive gains were also observed in children's understanding of germs, the associated illness threat and washing hands with soap as a prevention mechanism. The present study suggests that entertainment-education-based interventions have the potential to improve hygiene behavior among children while being low-cost.
