Building Healthy Lives in Rural Yunnan

The children were amazed to see the purple glow that emerged from on their classmate’s hands under the black-light. The idea of invisible bacteria and contaminants is difficult for anyone to understand. As part of CWEF’s health education curriculum, students participate in a simulation activity in which they see the transfer of ‘bacteria’ from hand to hand contact. The ‘bacteria’ is a transparent powder that is easily spread through contact. The transmission path can be seen when a black-light exposes the invisible fluorescent powder.

In December 2019, CWEF Health Director Jenny Chu led 30 children from two primary schools in Wuding county in rural Yunnan province through a two-day health education “Training of Trainers” session as a part of the HEAL (Health Education Advocacy & Literacy) program. These students will serve as health advocates—providing instruction and modeling to their peers in the areas of good hygiene and health promotion. 



The World Health Organization promotes proper hand washing to prevent illness and reduce the spread of disease. Once rural areas have access to reliable and safe drinking water, additional health and hygiene practices need to be introduced. Through the HEAL training, children learn how to thoroughly wash their hands and gain knowledge about bacteria and contaminant transmission. Through reference books, hands-on training, the germ-glow black-light simulation, and a handwashing song, student health advocates learn knowledge and practice good habits. They are also equipped to teach their peers about the importance of handwashing and serve as models for this healthy habit.

In addition to handwashing, the program addresses oral hygiene and proper teeth brushing techniques, healthy diet and nutrition, and importance of keeping a sanitary environment. The training provides children with critical information for healthy living and opportunities for the health advocates to engage with their peers by sharing the information and leading activities. CWEF gathers baseline information regarding the knowledge and personal hygiene practices of the students in order to provide supplemental training and information.
