Sennetsu Fever is a rare infectious disease belonging to a group of diseases known as the Human Ehrlichioses. These diseases are caused by bacteria belonging to the "Ehrlichia" family. Several forms of Human Ehrlichial infection have been identified including Sennetsu Fever, Human Monocytic Ehrlichiosis (HME), and Human Granulocytic Ehrlichiosis (HGE). Though caused by different strains of Ehrlichia bacteria, the disorders are all characterized by similar symptoms.
The symptoms of Sennetsu Fever may include a sudden high fever, headache, and muscle aches (myalgia) within a few weeks after initial infection. In some cases, affected individuals may also experience nausea, vomiting, and/or loss of appetite (anorexia). In addition, in many cases, abnormal laboratory findings may include a decrease in white blood cells (leukopenia) and/or an abnormal increase in the level of certain liver enzymes (hepatic transaminases). Sennetsu Fever is caused by the bacterium Ehrlichia sennetsu. The vector (or carrier) for this bacterium has not yet been determined; however, some researchers believe that infection may result from the ingestion of raw fish.
