Overview

Ehrlichiosis and anaplasmosis are similar tick-borne illnesses that cause flu-like symptoms, including fever, muscle aches and headache. Signs and symptoms of ehrlichiosis and anaplasmosis usually appear within 14 days after a tick bite.

If treated quickly with appropriate antibiotics, you'll likely recover within a few days. Untreated ehrlichiosis and anaplasmosis can result in serious or life-threatening complications.

The best way to prevent these infections is to avoid tick bites. Tick repellents, thorough body checks after being outside and proper removal of ticks are your best defenses against these tick-borne diseases.
