Ehrlichiosis and Anaplasmosis

Ehrlichiosis and Anaplasmosis are two distinct but related bacterial infections primarily transmitted to humans by tick bites. Both diseases can cause flu-like symptoms and are most common in areas where their specific tick vectors reside across the United States. Ehrlichiosis is caused by Ehrlichia species, and Anaplasmosis by Anaplasma phagocytophilum.
