Human Monocytotropic Ehrlichiosis is a tick-borne disease caused by the bacterium Ehrlichia chaffeensis. This disease is primarily transmitted to humans by the Lone Star tick (Amblyomma americanum).
Symptoms[edit]
The symptoms of Human Monocytotropic Ehrlichiosis typically appear within 1-2 weeks following the bite of an infected tick. Symptoms can include:
- Fever
- Headache
- Muscle aches
- Chills
- Nausea
- Confusion
- Rash (occurs in approximately 30% of adults and up to 60% of children)
