By Mayo Clinic staffEhrlichiosis is a bacterial illness transmitted by ticks. Ehrlichiosis causes flu-like symptoms. Another tick-borne infection — anaplasmosis — is closely related to ehrlichiosis. But the two have distinct differences and are caused by different microorganisms.
The signs and symptoms of ehrlichiosis range from mild body aches to severe fever and usually appear within a week or two of a tick bite. If treated quickly with antibiotics, ehrlichiosis generally improves within a few days.
Ehrlichiosis is most common in spring and summer, when ticks are active and you're more likely to be outdoors.
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 give you the best chance of avoiding ehrlichiosis.
