Treatment.--Cases of influenza should be isolated. Children should be put in a room by themselves and the other children of the family should not be permitted to see them. The rooms should be disinfected after the case is over. As complications are the dangerous element in grippe, we should try to prevent them. This can be best done by promptly putting the child in bed, making him comfortable, opening his bowels by castor oil or calomel. He should be made to drink hot lemonade. He should be kept on a light diet from which meat and vegetables are excluded. The above treatment will usually suffice in the ordinary uncomplicated grippe. If complications arise they must be treated according to the conditions. It is well to remember that the degree of prostration following a rather severe attack of grippe is out of all proportion to the extent of the disease. These little patients sometimes suffer considerably and do not regain their strength promptly. Experience has taught us that the best thing to do is to send them away. A change of climate will do wonders for them, more quickly and more thoroughly than all the medicine we can give them at home. The seashore is particularly good for them. DIPHTHERIA Diphtheria is an acute, specific, infectious, communicable disease. It affects the tonsils, throat, nose, or larynx. It is most frequently seen in children between the ages of two and five years, though it may appear at any time during life. The two sexes are equally liable to it. The same person may have the disease twice or more times at different ages. Children suffering from disease of the nose or throat are more likely to get it than are others. Such diseases are cold in the head with running nose, catarrh of the nose and throat, inflammation of the mucous membranes of the nose or throat.
