Brief Summary

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.

Study Arms (2)

Control Group

ACTIVE COMPARATOR

Participants in this group received standard hand hygiene education without culture media visualization using agar plates.

Behavioral: Standard Hand Hygiene Education

Intervention group

EXPERIMENTAL

Participants in this group received hand hygiene education supported by culture media visualization using agar plates. The agar plates were used to demonstrate bacterial colonies and visually reinforce the importance of effective handwashing.
