217. What constitutes the principal danger in Scarlet Fever?

The affection of the throat, the administration of opening medicine during the first ten days, and a peculiar disease of the kidneys ending in anasarca (dropsy), on which account, the medical man ought, when practicable, to be sent for at the onset, that no time may be lost in applying proper remedies.

218. How would you distinguish between Scarlet Fever and Measles?

Measles commences with symptoms of a common cold; scarlet fever does not. Measles has a peculiar hoarse cough; scarlet fever has not. The eruption of measles is in patches of a half-moon shape, and is slightly raised above the skin; the eruption of scarlet fever is not raised above the skin at all, and is one continued mass. The color of the eruption is much more vivid in scarlet fever than in measles. The chest is the part principally affected in measles, and the throat in scarlet fever.

There is an excellent method of determining, for a certainty, whether the eruption be that of scarlatina or otherwise. I myself have, in several instances, ascertained the truth of it: “For several years M. Bouchut has remarked in the eruption of scarlatina a curious phenomenon, which serves to distinguish this eruption from that of measles, erythema, erysipelas, etc., a phenomenon essentially vital, and which is connected with the excessive contractability of the capillaries. The phenomenon in question is a white line, which can be produced at pleasure by drawing the back of the nail along the skin where the eruption is situated. On drawing the nail, or the extremity of a hard body (such as a pen-holder), along the eruption, the skin is observed to grow pale, and to present a white trace, which remains for one or two minutes, or longer, and then disappears. In this way the diagnosis of the disease may be very distinctly written on the skin; the word ‘Scarlatina’ disappears as the eruption regains its uniform tint.”[[230]]

219. Is it of so much importance, then, to distinguish between Scarlet Fever and Measles?

It is of great importance, as in measles the patient ought to be kept moderately warm, and the drinks should be given with the chill off; while in scarlet fever the patient ought to be kept cool—indeed, for the first few days, cold; and the beverages, such as spring water, toast and water, etc., should be administered quite cold.

220. What is the treatment of Scarlet Fever?[[231]]

What to do.—Pray pay particular attention to my rules, and carry out my directions to the very letter—as I can then promise you that if the scarlet fever be not malignant, the plan I am about to recommend will, with God’s blessing, be generally successful.

What is the first thing to be done? Send the child to bed; throw open the windows, be it winter or summer, and have a thorough ventilation; for the bedroom must be kept cool, I may say cold. Do not be afraid of fresh air, for fresh air, for the first few days, is essential to recovery. Fresh air, and plenty of it, in scarlet fever, is the best doctor a child can have: let these words be written legibly on your mind.[[232]]
