Reference
Ehrlichiosis and anaplasmosis are two closely related tick-borne diseases, caused by different germs. Although both diseases concentrate east of the Rocky Mountains, they usually occur in different areas. Ehrlichiosis, or human monocytic ehrlichiosis (HME), is found mainly in the mid-Atlantic, southeastern, and south central states. Anaplasmosis (formerly called human granulocytic ehrlichiosis, or HGE) occurs more often in the Northeast and upper Midwest.
