- Anaplasmosis is one of several tickborne
diseases in Minnesota.
- Anaplasmosis is a bacterial disease transmitted to humans by Ixodes scapularis
(blacklegged tick or deer tick), the same tick that transmits Lyme disease. The tick must be attached at least 12-24 hours to transmit the bacteria that cause anaplasmosis. Not all ticks carry these bacteria.
Signs and symptoms
The signs and symptoms of anaplasmosis may include:
- Severe headache
- Muscle aches
- Chills and shaking
- Less frequent symptoms of anaplasmosis include nausea, vomiting,
loss of appetite, weight loss, abdominal pain, cough, diarrhea, aching
joints and change in mental status.
- Although people of any age can get anaplasmosis, it tends to be most severe in the aging or immune-compromised. Severe complications can include respiratory failure, renal failure and secondary infections.
- If anaplasmosis is suspected, see your doctor immediately.
- Early diagnosis and treatment can reduce the time a person is ill
and the severity of the disease.
- Anaplasmosis is treated with antibiotics.
- Anaplasmosis was first recognized during 1993
in several patients from Minnesota and western Wisconsin; the disease
was known as human granulocytic ehrlichiosis (HGE) at that time. It was renamed anaplasmosis in 2003.
- A related form of ehrlichiosis caused by Ehrlichia chaffeensis
is found throughout much of southeastern and south-central United States
but is not a common disease in Minnesota at this time, although a small number of cases have been reported.
Ehrlichiosis due to E. chaffeensis is carried by a different species of tick, the Lone Star tick, which is most common in southern states.
- Another related form of ehrlichiosis caused by Ehrlichia muris-like agent was identified in Minnesota and Wisconsin patients in 2009. Since then, low numbers of cases have been reported in both states. Ixodes scapularis (blacklegged tick or deer tick) may carry this disease agent and transmit it to people.
