Symptoms

Signs and symptoms of ehrlichiosis and anaplasmosis are generally the same, although they usually are more severe in ehrlichiosis. Symptoms of ehrlichiosis and anaplasmosis, which vary widely from person to person, include:

• Moderate fever
• Chills
• Headache
• Muscles aches or pains
• General feeling of being unwell
• Joint pain
• Nausea
• Vomiting
• Diarrhea
• Loss of appetite

Additional signs and symptoms associated with ehrlichiosis but rarely with anaplasmosis include:

• Confusion or changes in mental state
• Rash

Some people may be infected and not develop symptoms.

When to see a doctor

The time from getting a bite to showing signs and symptoms is usually five to 14 days. If you develop any of the signs or symptoms after a tick bite or after a possible exposure to ticks, see your doctor.
