The Effect of Culture Media Visualization-Supported Hand Hygiene Education on Handwashing Behavior in Preschool Children

The hand hygiene educational intervention supported by culture medium visualization was found to be an effective practice in promoting proper handwashing behaviors and reducing hand microbial load in children aged 5-6 years. The educational intervention featuring culture plate demonstrations applied to the intervention group was determined to be highly effective in achieving hand hygiene and reducing hand bacterial load. In contrast, the control group received traditional education, which did not yield a statistically significant difference.
