Human Granulocytic Ehrlichiosis (HGE) is a rare infectious disease that belongs to a group of diseases known as the Human Ehrlichioses. The Ehrlichioses are infectious diseases caused by bacteria in the "Ehrlichia" family. Several forms of Human Ehrlichial infection have been identified including Human Granulocytic Ehrlichiosis (HGE), Sennetsu Fever, and Human Monocytic Ehrlichiosis (HME). Though caused by different strains of Ehrlichia bacteria, the disorders are all characterized by similar symptoms.
The symptoms of Human Granulocytic Ehrlichiosis (HGE) may include a sudden high fever, headache, muscle aches (myalgia), chills, and a general feeling of weakness and fatigue (malaise) within a week or so after initial infection. In most cases, abnormal laboratory findings may occur including an abnormally low number of circulating blood platelets (thrombocytopenia), a decrease in white blood cells (leukopenia), and an abnormal increase in the level of certain liver enzymes (hepatic transaminases). In some cases, symptoms may progress to include nausea, vomiting, cough, diarrhea, loss of appetite (anorexia), and/or confusion. If Human Granulocytic Ehrlichiosis is left untreated, life-threatening symptoms, such as kidney failure and/or respiratory problems, may develop in some cases. Human Granulocytic Ehrlichiosis is caused by a bacterium of the Ehrlichiosis family that has not yet been named. The Ehrlichial bacterium is carried and transmitted by certain ticks (vectors), such as the deer tick (Ixodes scapularis) and the American dog tick (Dermacentor variabilis).
