The diet in ordinary cases of measles does not require special care beyond that described under the section on Diet in Fever in General. The appetite is usually wanting in the prodromal and eruptive stages, and milk with farinaceous gruels answers every requirement. Thirst is prominent, and cool water or lemonade may be offered, or orange juice or unfermented grape juice in Vichy. Alcoholic stimulation is only needed if the patient is very feeble, or if severe complications arise. The resumption of a solid diet must be gradual, but it may begin as soon as the fever and catarrhal symptoms disappear.
When nursing or hand-fed infants have measles they should be fed somewhat oftener than usual, and must be given less food at each feeding. A child of eight or ten months of age should be fed on diluted milk like one two or three months younger. In this manner any existing catarrh of the stomach is less likely to cause serious indigestion and vomiting. It is particularly necessary to give water, and half an ounce should be offered at least every two hours, or oftener, while the infant is awake.
For mumps no special diet is required beyond the necessity of giving fluids or soft food while the swelling of the parotid glands and fever last. The suggestions for the dietetic treatment of tonsillitis apply to this disease. Anaemia is apt to be extreme during convalescence, and meats should therefore be plentifully supplied. Cod-liver oil is very appropriate in protracted convalescence.
