Sennetsu Fever
Overview
A rare infectious disease caused by a bacteria called Ehrlichia sennetsu.
Symptoms
* Sudden high fever * Headache * Muscle ache * Nausea * Vomiting * Loss of appetite * Reduced white blood cell count * Increased liver enzyme level
Causes
Ehrlichiosis is caused by Ehrlichia organisms, specifically E. chaffeensis and granulocytic Ehrlichia. Known vectors include the lone star tick (Amblyomma americanum), the American dog tick (Dermacentor variabilis), and deer ticks (Ixodes dammini and Ixodes scapularis). In the United States, most cases of ehrlichiosis are reported in the south-central and southern Atlantic areas of the country, but it has also been reported in the upper midwest. Persons at highest risk include those who live in endemic and highly wooded areas, engage in activities in high grassy areas, and own a pet that may introduce a tick into the home.
Diagnosis
* Cold & Flu: Home Testing: * Home Fever Tests * Home Ear Infection Tests * Home Flu Tests
Treatment
Ehrlichiosis is treated with tetracycline or doxycycline, producing rapid improvement when used early in the disease's course. Death can occur if treatment is delayed. PEDIATRIC TIP Oral tetracycline usually isn’t prescribed for children until all permanent teeth have erupted because it can permanently discolor teeth that are still forming. Supportive therapy is provided to help relieve signs and symptoms.
