    Rocky Mountain spotted fever (RMSF) is the most serious tick-borne disease in the United States and is caused by Rickettsia rickettsii, a type of bacteria known as rickettsia. These bacteria are transmitted to humans by the bite of certain hard ticks. The two most important species of ticks that can transmit R. rickettsii in the United States are Dermacentor variabilis (the American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick). A third species, Rhipicephalus sanguineus (brow...

    Although first recognized in the late 19th century in the Rocky Mountain region, by 1930s this disease was found to be present in the eastern portion of the country as well. The wood tick (Dermacentor andersoni), one of the main tick vectors is found in the Rocky Mountain states and southwestern Canada. The second major vector is the American dog tick (Dermacentor variabilis). This tick is distributed east of the Rocky Mountains and in some regions along the Pacific Coast. The cayenne tick (A...

    Symptoms of Rocky Mountain spotted fever usually appear 2 to 14 days (average of 7 days) after being bitten by the infected tick. Fever is often the first symptom experienced by patients.

Nausea, vomiting, severe headache, muscle pain and lack of appetite are also sometimes reported by patients in the early stage of disease. Other clinical symptoms include abnormal pla...

    Clinical diagnosis of RMSF is based on serological tests including detection of antibody titers via IFA, detection of the bacterial agent via culture or immunohistochemical staining of biopsies, and by detection of bacterial DNA in a clinical specimen via PCR. However, treatment decisions should not be delayed while waiting for confirmation with laboratory results. Patients with a relevant history and symptomology should be treated with the appropriate antibiotic regimen immediately. Since th...

    Upon suspicion of Rocky Mountain spotted fever, treatment should begin immediately. Delay of treatment has been associated with fatal outcomes. Treatment with tetracycline or chloramphenicol antibiotics can be used to treat RMSF. Doxycycline (a tetrycycline) antibiotic is the treatment of choice for both adults and children. However doxycycline is not recommended for use by pregnant women. Current recommendations from the Centers for Disease Control and Prevention (CDC) include doxycycline th...
