INFECTIOUS DISEASES.
INFECTION AND CONTAGION.—These words are often used in such a way that a wrong impression is made. A disease may be infectious but not contagious. Malaria is an instance. Infection means an ability to enter the body from any source, wind, water, food or other persons and produce a characteristic disease. The agency doing this is known as a germ. Contagion is properly a poisoning of one individual from contact with a diseased individual in some way known or unknown. It may be conveyed indirectly through clothes, etc., or other person; but always comes from some person sick with the same disease. Diseases may be both infectious and contagious. Nearly all the epidemic diseases of infancy are both infectious and contagious and accompanied by fever. In nursing children, suffering from infectious diseases the mother or nurse should avoid their breath and handle them as little as possible. All secretion from bowels and kidneys should fall in a vessel containing a disinfecting solution of Copperas, bichloride of mercury, etc., and should be emptied into the sewer or buried. Following are the solutions as made. Copperas:—Put a lump as big as a walnut in the chamber with one-half pint of water, to receive feces, urine, sputum and vomited matter from infectious and contagious patients.
2. Solution of chlorinated soda, four fluid ounces; water ten ounces, useful for hands and dishes, not silverware. Dissolve eight corrosive sublimate tablets, also called bichloride, in a gallon of water. This is used to disinfect floors, woodwork, rubber, and leather, but not metal parts. Great care must be taken to have the hands washed after handling such a patient, so as not to infect the food, eyes, mouth, or any small skin sores.

Diet in Infectious Diseases.—Foods that can be used: Milk, milk-water, milk and lime-water, Mellin's food, malted milk, imperial granum, albumin water, rice water, oatmeal water, barley water, egg (white part), and barley water, arrowroot water, whey, whey and cream mixture, cream and rice mixture, beef tea, beef extract, mutton broth, beef juice. Chewing broiled steak and only swallowing the juice, dry toast and soft boiled eggs, milk toast, dried beef broth, soups, rice, cornstarch, tapioca, etc. The diet must not consist of solid food in any severe case of fever. Small quantities of cold drinks can be given, frequently repeated if there is no vomiting. Frequent washing with tepid water or cool water lessens the fever and produces sleep. The bowels should be kept open at least once a day, and castor oil or salts usually can be given. (See Nursing and Dietetics department.)

SCARLET FEVER. Definition.—Scarlet fever is an acute infectious disease, with a characteristic eruption.
Modes of Conveying.—The nearer a person is to a patient the more likely one is to take or convey the disease. Clothing, bedding, etc., may retain the poison for months. Scales from the skin of a patient, dried secretions, the urine if inflammation of the kidneys (nephritis) exists, the discharges (feces) from the bowels, are all means of infection. The longer a person remains near the patient the more likely he is to convey the disease. Foods handled by those sick of the disease, or by those who may have been near patients may convey the disease. This is especially true of milk. Epidemics of scarlet fever have been started by dairy-men who had scarlet fever in their family. I once attended a family where the only known cause for it in that family was a long-haired dog of a neighbor who had scarlet fever in the family. The dog was in the room with the sick ones, and visited the neighbor's family and played with the children who afterwards came down with the fever. Discharges from the ear, caused by scarlet fever, are said to be capable of giving it.

Remains in the Room, how long?—It may remain for months in a room, and extend over two years as recorded by Murchison. We do not yet know how the poison obtains entrance to the body. Hence, the need for thorough disinfection.
