Joseph R. Gay, Progress and Achievements of the Colored People
“ Scarlet fever is a noteworthy instance of a disease which constantly spreads by carelessness. Just as long as the scaling or shedding of the outer skin continues contagion may be carried, for it is these scales which bear it. It is nothing less than criminal, therefore, to permit the patient who is recovering to mix with other persons, except those who have been caring for him already. In the early stages of the disease the infection is chiefly in the breath, and in the secretion of the nostrils. ”
