The rash often makes its appearance within twenty-four hours after the commencement of the illness, at latest in the course of the second day. It usually shows itself first on the neck, breast, and face, whence it extends in twenty-four hours to the body and limbs, and is then not seldom specially vivid on the inside of the thighs. Its colour is a very bright red, due in part to a general flush of the skin, in part to the presence of innumerable red dots or spots, which do not communicate any sense of roughness to the hand, though now and then extremely minute red pimples are interspersed. For three days the rash usually continues to become of a deeper colour, and more generally diffused over the whole surface; it then slowly declines, but does not wholly disappear until the seventh or eighth day of the disease. As the rash subsides the skin is left rough, and by degrees scales off, often in large flakes from the hands and feet, but elsewhere in a sort of branny scales. Sometimes this process is over in five or six days, while in other cases the skin peels and is reproduced several times in succession, so that it is protracted for three or four weeks or even longer. The degree of this peeling also varies as well as its duration. It is usually most considerable where the rash has been most abundant, while where the rash has been scanty, it is sometimes scarcely apparent except at the tips of the fingers and toes and just around the insertion of the nails.

Besides the rash there are commonly other symptoms not less characteristic of scarlatina, and among them the sore-throat is one of the most invariable. Even in mild cases, it is very rarely absent, and if not present at the beginning, it comes on on the second or third day. The palate and tonsils, in these circumstances are red, and the latter are usually more or less swollen, while swallowing is attended with pain, or at any rate with discomfort. The redness of the palate, which extends also to the back of the throat, is a finely spotted redness closely resembling the rash on the surface. The tongue is coated with a thick white or yellowish coating, through which project numerous bright red points, papillæ as they are called, and this appearance of the tongue is as distinctive of scarlatina as the rash itself. Later, as the rash begins to fade, the coating separates from the tongue, which is left of a bright red colour, looking raw and shining, with the little raised red points projecting beyond its surface, and constituting what has been called in medical language, the strawberry tongue.

When all these symptoms are present, no one can doubt but that the case is one of scarlatina. But the decision is far less easy in mild cases, for in them the rash is sometimes extremely evanescent, the general disturbance of health very slight, and the fever and accompanying rise of temperature small. The risk in such circumstances of the disease being altogether overlooked is even greater than that of its being confounded with some other eruptive fever. The rash of measles cannot be confounded with that of scarlatina, and the distinctly spotty character of the rash of German measles ought, apart even from other differences, to render mistake impossible.

Perhaps the best rule that can be laid down is that every diffused red rash, not obviously formed by distinct spots, even though it be not uniform but appears in patches on the neck, breast, back, or inside of the thighs, and persists for more than twelve hours, is scarlatinal. Further, that in any instance in which even very slight feverishness, or very slight sore-throat, have preceded or accompanied the rash, the nature of the ailment is stamped beyond the possibility of doubt. Mistakes are made from want of careful observation, much more than from any insuperable difficulty in distinguishing one disease from the other. When the least hesitation is felt as to the nature of any rash which may appear on a child, with, or without previous illness, the question should be at once referred to a medical man. People are too apt in these circumstances to wait for a few days, and then to appeal to the doctor when all traces of rash have disappeared, and when the grounds no longer exist on which he could base a positive opinion.

I need not describe the symptoms of severe and dangerous scarlatina, for long before symptoms become really formidable, the patients will have been placed under medical care. It may suffice to say that the danger is almost always in proportion to the severity of the throat-affection and swelling of the glands, and not at all in proportion to the abundance of the rash. Though severe cases usually set in with severe symptoms, yet this is not invariably the case, and medical watching is all the more necessary from the very commencement, since until the end of the first week it is impossible to calculate on the subsequent course of the disease. In malignant scarlatina happily of infrequent occurrence, the child is struck down, as though its blood were poisoned, from the very first; and death takes place often within forty-eight hours, the rash appearing just sufficiently to stamp the nature of the pestilence which has proved so deadly.

It may form a useful conclusion to all that has been said in this little book about the diseases of children, if I endeavour to point out in what consist the duties of parents in cases of scarlatina, or of any disease which resembles it.

1. To watch carefully the commencement of every slight feverish attack in which a diffused red rash appears, even though this should be only in patches, and to bear in mind the possibility of its being due to scarlatina.

2. To remove the child immediately from the others, so long as there is any doubt concerning the nature of the case, and to remove with him his bed, bedding, and all clothes worn by him at the time when the illness began, or the rash appeared.

3. To place the child if possible in a room at the top of the house, so that the other children may not pass by his door.

4. Inasmuch as scarlatina often proves fatal to grown persons who have not already had the disease, to obtain at once the attendance of a skilled nurse, in order to avoid the risk of the disease spreading through the household.
