Globally about 500,000 children die each year due to diarrheal infection, but many lives could be saved with better hand hygiene.
Now a primary school in Kerala, India has taken part in a trial using a robot to encourage children to spend more time washing their hands.
Pepe the robot offers hygiene advice from the World Health Organisation as part of a study by universities in Scotland and India.
The robot’s presence prompted a 40% increase in time spent at the sink. The machine’s creators believe the robot’s facial features are the reason for its success.
