Ehrlichiosis, human, is the general concept for diseases caused by the bacterium Ehrlichia chaffeensis, E. ewingii, or E. muris eauclairensis. These bacteria are typically transmitted to humans by biting infected ticks such as the lone star tick (Amblyomma americanum) and the black-legged tick (Ixodes scapularis).
Muscle aches, chills, fever, headache, and sometimes an upset stomach are common symptoms of ehrlichiosis, human. Doxycycline is the preferred therapy for ehrlichiosis in adults and children of all ages.
Avoiding tick bites is the best approach to avoid these diseases. Tick repellents, thorough body checks after being outdoors, and effective tick removal are your best lines of protection against tick-borne infections.
