Ehrlichiosis is a broad term used for infections caused by Ehrlichia bacterial species. The symptoms commonly seen with these infections include fever, headache, chills, malaise, muscle pain, nausea, vomiting, diarrhea, confusion, rash, and conjunctival injection. Symptoms will vary for individuals.

 

Ehrlichiosis can be a very serious disease if not treated correctly. Individuals who are immunocompromised are more likely to have severe disease.

 

Arizona will typically see 1 to 4 cases of ehrlichiosis reported each year.

 

Arizona 5 year median: 2 cases
