Q. What are the symptoms of Anaplasmosis or Ehrlichiosis?

A. Like Lyme disease, Anaplasmosis and Ehrlichiosis infections peak during May, June, and July and the symptoms typically appear from a week to a month after infection. The initial symptoms are flu-like and can include high fever, chills, headache, fatigue, and general achiness. Fewer than half of infected people report a rash. The rash is different from a Lyme disease rash; it is usually smaller and may have raised areas. The rash is more common in children than adults. Children may also suffer from swelling of the hands and feet. Other symptoms may develop later, including nausea, diarrhea or constipation, loss of appetite, cough, stiff neck, confusion, and weight loss. Untreated, the disease can sometimes be fatal in a few weeks, especially in children.

Q. How are Anaplasmosis and Ehrlichiosis diagnosed?

A. There are blood tests for Anaplasmosis and Ehrlichiosis, which vary in accuracy and reliability depending on when the test is performed and the lab performing the test. It is difficult to obtain an accurate test result during the first few weeks after infection.

Q. How are Anaplasmosis and Ehrlichiosis treated?

A. Anaplasmosis and Ehrlichiosis are usually treated with doxycycline. Most cases respond quickly when diagnosed and treated promptly. However, about 1-2% of these patients will die if treatment is not initiated right away. Like Lyme disease, you can get these diseases over and over again from new tick bites.
