Human Granulocytic Ehrlichiosis
Human Granulocytic Ehrlichiosis (HGE) is a rare infectious disease characterized by the following symptoms:
(HGE) may include; sudden high fever, headache, muscle aches, 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; abnormally low number of blood platelets (thrombocytopenia), a decrease in white blood cells (leukopenia), and an abnormal increase in certain liver enzymes (hepatic transaminases – ALT & AST). 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. The Ehrlichial bacteria is carried and transmitted by certain ticks, such as the deer tick and the American dog tick.
