The Road of Health (1938)

The lecturer shows a microcinematographic sequence of spirochaetes and drawings of the gonoccus (the bacteria responsible for syphilis and gonorrhea). He then turns to an easel and begins to draw 'the road of health'; the cartoon takes this up in magic drawing, in a style that is highly reminiscent of the 'Giro the Germ' series made for the Health and Cleanliness Council a few years before.

Unfortunately the movie The Road of Health is not yet available on Disney Plus.
