261 – Anaplasmosis (aka Ehrlichiosis)
Excerpted from the ALDF.
Human granulocytic anaplasmosis (HGA), previously known as human granulocytic ehrlichiosis (HGE), is a tick-associated disease caused by a species of bacteria called Anaplasma phagocytophilum. HGA is transmistted to humans by the bite of the deer tick and western black-legged tick.
People exposed to the disease agent often have difficulty being diagnosed because of the non-specific nature of the symptoms. Most experience headaches, fever, chills, myalgia, and malaise that can be confused with other infectious and non-infectious diseases. Rashes are rarely reported by people exposed to HGA.
