The feeding of the malaria patient is important. Between the attacks of fever, or during the sweating stage, he should be given food in fluid form, such as chicken broth, eggs beaten up with milk, raisin tea, etc.; and as soon as his stomach will stand it, the diet should be increased. Tonics, such as iron and arsenic, are required during convalescence. In cases where there is acute malarial poisoning, with temperature 106° F., or even higher, do not wait to undress the patient or get a bath; but empty gallons of water over him, one boy keeping the head constantly soused; while this is being done a bath can be procured and the patient then undressed, or, better still, have his clothes cut off, because it is dangerous to lift such a patient about too much. Remember that when a patient is very ill and weak, he should not be allowed to stand or sit up suddenly, as he may faint. Delirium with high temperature, say 106° F. or over, is a certain sign that the fever is doing harm, and must be reduced. The temperature and pulse should be carefully watched when the cold water treatment is employed. _Malta Fever._ (See _Undulant Fever._) _Measles._ Incubation period, ten days. Rash occurs on the fourth day. _Rash._—Pink spots, round or irregular, slightly raised above the surface, tending to run together in patches over the body, leaving the unaffected skin between them clear. In the early stages often best marked on the face and behind the ears. _Symptoms._—Fever, catarrh, congested eyes, running from the nose, sickness and cough. _Treatment._—Similar to that of scarlet fever (_see_ p. 222). It is very important to guard against chill; to ensure plenty of fresh air. _Complications._—Measles may be followed by pneumonia. _Mumps._ This is an infectious disease, characterised by swelling of the salivary glands. Its chief importance to the traveller is that if once it makes its appearance it may spread rapidly through his native attendants, and that it is apt to be followed by inflammation of the testicle. _Symptoms._—The invasion is accompanied by fever, which is usually slight, but is sometimes severe. There is pain just below the ear on one side, followed by a swelling which gradually increases, causing great enlargement of the neck and side of the cheek. In a day or two the other side of the face is usually affected, and sometimes the condition spreads under the lower jaw. It persists from seven to ten days, then gradually subsides. Inflammation of the testicle may be troublesome. It is usually one-sided. _Treatment._—Rest in bed during the height of the disease. Get the bowels freely open and keep the patient on a light diet. No medicine is required unless the fever is high. Either cold or hot applications may be made to the swelling. If the testicle is involved it should be treated by rest and protection with cotton wool. _Myiasis._
