Through the cinematographic representation of the rural teacher, the social worker and the malaria sprayer man, whom I called sanitarians intermediaries, the recreation of the malaria eradication campaign of 1957 and tuberculosis prevention campaign of 1960, this article analyze in four époque films the presence of a visual and oral discourse full of nationalistic symbols that overdo the Mexican state labor in public health activities. I confirm that Mexican health films of the ending fifties used as education health tools, functioned as mass media propaganda for health authorities in order to create an image of a Modern and healthy Mexico.
