Ehrlichiosis

Ehrlichiosis is a bacterial infection transmitted by tick bites.

Symptoms are similar to Rocky Mountain spotted fever and Lyme disease.

Onset of symptoms occurs 5-10 days after the tick bite with sudden fever, headache, chills, aches and nausea and vomiting.

A generalized rash occurs more often in affected children compared to adults.

Untreated meningitis, kidney and liver disease may occur, and rarely it is fatal.
Diagnosis is with blood tests, which may take some time.

Doxycycline is effective treatment (which will also cover Rocky Mountain Spotted Fever and Lyme disease), while waiting for confirmation of blood work.
