Let every room be _lime-washed_ and then be whitewashed; if the contagion has been virulent, let every bed-room be freshly papered (the walls having been previously stripped of the old paper and then lime-washed); let the bed, the bolsters, the pillows, and the mattresses be cleansed and purified; let the blankets and coverlids be thoroughly washed, and then let them be exposed to the open air—if taken into a field so much the better; let the rooms be well scoured; let the windows, top and bottom, be thrown wide open; let the drains be carefully examined; let the pump water be scrutinized, to see that it be not contaminated by fecal matter, either from the water-closet or from the privy; let privies be emptied of their contents—_remember this is most important advice_—then put into the empty places lime and powdered charcoal, for it is a well-ascertained fact that it is frequently impossible to rid a house of the infection of scarlet fever without adopting such a course. “It would be well if we were to use whitewash in many cases where great cleanliness of surface cannot be obtained. We remove in this way, by an easy method, much of the dullness and still more of the unwholesomeness of dirt.”—Dr. Angus Smith. “In St. George’s, Southwark, the medical officer reports that scarlatina ‘has raged fatally, almost exclusively where privy or drain smells are to be perceived in the houses.’” Let the children who have not had, or who do not appear to be sickening for scarlet fever, be sent away from home—if to a farm-house so much the better. Indeed, leave no stone unturned, no means untried, to exterminate the disease from the house and from the neighborhood. 223. _Will you describe the symptoms of Chicken-pox?_ It is occasionally, but not always, ushered in with a slight shivering fit; the eruption shows itself in about twenty-four hours from the child first appearing poorly. It is a vesicular disease. _Vesicles._ Small elevations of the cuticle, covering a fluid which is generally clear and colorless at first, but becomes afterward whitish and opaque, or pearly.—_Watson._ The eruption comes out in the form of small pimples, and principally attacks the scalp, the neck, the back, the chest, and the shoulders, but rarely the face; while in small-pox the face is generally the part most affected. The next day these pimples fill with water, and thus become vesicles; on the third day they are at maturity. The vesicles are quite separate and distinct from each other. There is a slight redness around each of them. Fresh ones, while the others are dying away, make their appearance. Chicken-pox is usually attended with a slight itching of the skin; when the vesicles are scratched the fluid escapes, and leaves hard pearl-like substances; which, in a few days, disappear. Chicken-pox never leaves pit-marks behind. It is a child’s complaint; adults scarcely, if ever, have it. 224. _Is there any danger in Chicken-pox; and what treatment do you advise?_
