Do you smell baking? According to a 1976 medical journal article, patients afflicted with typhoid fever "emit a smell comparable to freshly baked brown bread" [source: Liddell]. That may actually sound kind of pleasant, but rest assured that typhoid fever is anything but.
Patients with this disease usually develop a sustained fever as high as 103 to 104 degrees F (39 to 40 degrees C), and suffer stomach pains and headaches, as well as weakness. In some cases, they also experience a rash of flat, rose-colored spots. About 21.5 million people die from typhoid fever each year, mostly in developing countries. It's spread by eating food or drinking water handled by someone who already has the disease and is shedding the Salmonella Typhi bacteria [source: CDC].
