Class C, aliens who present a defect or disease of still lesser seriousness, not affecting ability to earn a living, but which none the less must be certified for the information of the immigration inspectors.

Under class A, the excluded, are listed idiots, imbeciles, the feebleminded, the epileptics, the insane, persons afflicted with tuberculosis of the respiratory, intestinal or genito-urinary tracts, and loathsome or dangerous contagious diseases. By contagious the law means communicable.

Loathsome contagious diseases include those whose presence excites abhorrence in others, and which are essentially chronic, such as favus, ringworm of the scalp, parasitic fungus diseases, Madura foot, leprosy and venereal disease.
