"This film was made to promote the public's awareness about hygiene. It is a rare film composed only of animation, with no live-action. At the time, the Ministry of Education released science films made using microscopic cinematography, such as Infectious Bacteria (傳染病の病原體, 1925), The Life of a Mosquito and the Spread of Disease (蚊の一生と疾病の傳播, 1925) and Flies and Diseases (蠅とその害毒, 1926). This work is an animation film made based on the achievements of these science films."
