When the disease sets in with a severe rigor the fever frequently rises at once to 103 or 104 degrees F. In the lightest forms the fastigium may be almost absent; defervescence setting in upon the first day of the fastigium and in many cases defervescence occurs at the end of the second week and the temperature may fall rapidly, becoming normal in ten or twenty hours. This fall in the temperature may take place without any apparent cause or it may follow an intestinal hemorrhage. The temperature often falls many hours before the blood appears in the evacuations. The occurrence of peritonitis is also marked by a sudden fall in the temperature. =Hyperpyrexia= in typhoid fever is not very common except just before death. After the temperature has been normal for several days there may be a sudden rise of the temperature to 102 or 103 degrees F. This may persist for a couple of days and then return rapidly to the normal. These =recrudescences=, as they are called, are quite common and are caused most frequently by errors in the diet, constipation, excitement or mental emotion. These elevations in the temperature are found most frequently in children and persons of a nervous temperament. =Afebrile Typhoid= is of very rare occurrence. The patient has all the characteristic symptoms of typhoid fever with the exception of a fever. The =rash= is highly characteristic. It appears about the eighth or tenth day, usually upon the skin of the abdomen or chest, rarely found elsewhere on the body. It consists of a variable number of rose colored spots distinctly elevated, and disappear on pressure. These spots last three or four days and appear in successive crops. Vivid red erythematous eruptions upon the chest and abdomen are commonly seen during the first week of typhoid fever. Urticaria is rarely seen. Sweating characterizes some cases of typhoid fever, but generally the skin is dry. This may occur with or without chilly sensations or actual rigors. In some cases there may be recurring paroxysms of chills, fever, and sweats and they may be mistaken for intermittent fever. Edema of the skin may occur and is usually due to anemia or cachexia and sometimes to nephritis. Local edema may occur as the result of vascular obstruction, particularly thrombosis of the femoral vein. There is a peculiar musty odor exhaled from the skin in typhoid fever, particularly if the skin has been neglected. In all protracted cases =bed-sores= are likely to develop. The =hair= is apt to fall out but is generally renewed. The nails also suffer and ridges can usually be observed upon them.
