The rarest and most unstudied type of the disease is endemic. It barely happens in the wealthy regions of the world. Usually, the carriers of these bacteria can be noticed in the places with a low level of hygiene. In addition, the environment must be cold to let the carriers live and reproduce. Many people know this disease more as the ‘jail fever’ as mostly prisoners suffer from this problem due to the poor hygiene and pretty low temperatures. Except for the tiny parasites, the rats and mice also may pass this sort of typhus to people.
Let’s say, the infected flea or rat bite someone. The signs of endemic typhus progress within 1-2 weeks. The infection starts evolving in the body immediately, but such thing as fever can be noticed in a week only. The temperature of the body is usually extra high. The patients may feel extreme headaches. They feel like vomiting all the time. They lose their appetite as well as a lot of water, which can be explained by the facts of diarrhea. In addition to these symptoms, malaise takes place. The visual effect is the reddish spots that form a rash (develops in a week or less). The attacked regions are the chest and abdomen. It may be followed by a cough. Only two percent of patients used to die.
