Human Granulocytic Anaplasmosis

From Wikipedia, the free encyclopedia

Human Granulocytic Anaplasmosis (HA) is the recent term for what up until 2003 was known as human granulocytic ehrlichiosis (HGE).

Human anaplasmosis is an infectious disease caused by a bacteria which can be transmitted to humans by Ixodes scapularis, also known as the deer tick or the black-legged tick. This is the same tick that can transmit Lyme disease. Fortunately early treatment with antibiotics is oftern successful.

Syptoms are often confused with generalized flu symptoms such as a fever, severe headache, muscle aches and chills and shaking.
