    • 2010- 2.5 cases per million persons [1]

Endemic Regions

  • The lone star tick (Amblyomma americanum) is the primary vector of both Ehrlichia chaffeensis and Ehrlichia ewingii in the United States.
    • E. chaffeensis is most common in the south central and southeastern states.
    • E. ewingii is most common in the south central and southeastern states.
    • A. phagocytophilium is endemic to New England and the north central and Pacific regions of the United States.
