Acute HME Syndrome

Acute HME Syndrome, also known as Human Monocytic Ehrlichiosis (HME), is a tick-borne disease caused by the bacterium Ehrlichia chaffeensis. This disease is primarily transmitted to humans through the bite of an infected lone star tick (Amblyomma americanum).

Symptoms[edit | edit source]

The symptoms of Acute HME Syndrome typically appear within 1-2 weeks following a tick bite and may include fever, headache, muscle aches, and fatigue. Some patients may also develop a rash. If left untreated, the disease can progress to a more severe form, leading to complications such as meningitis, respiratory distress syndrome, and kidney failure.

Diagnosis[edit | edit source]

Diagnosis of Acute HME Syndrome is typically based on clinical symptoms, history of tick exposure, and laboratory testing. Blood tests are used to detect antibodies to Ehrlichia chaffeensis and to identify the bacterium in the blood.

Treatment[edit | edit source]

Treatment for Acute HME Syndrome typically involves the use of antibiotics, such as doxycycline, which is most effective when started early in the course of the disease. In severe cases, hospitalization may be required.

Prevention[edit | edit source]

Prevention of Acute HME Syndrome primarily involves avoiding tick bites through the use of insect repellent, wearing long sleeves and pants, and checking for ticks after spending time in wooded or grassy areas.
