HGE: Human Granulocytic Erlichiosis

HGE is similar to lyme disease both in symptoms, effects, and method of transmission. There are small differences, one being that HGE's vector is the North Star tick as well as the deer tick.
Signs and symptoms of HGE include fever, chills, headache, muscle aches, nausea, and vomiting. Laboratory findings often include elevated liver enzymes and a decrease in a patient's blood platelets and white blood cells. HGE typically lasts one to two weeks, and most patients who receive treatment recover without long-lasting complications. However, a small proportion of patients with HGE may suffer more severe symptoms, such as kidney failure, respiratory problems, or meningitis. The case-fatality rate for both diseases may be as high as 5 percent. Severe infections and death are most likely in older people, and in those who are not promptly treated. HGE is generally treated with a minimum seven-day course of tetracycline or doxycycline.
