    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. The classic triad of fever, rash and tick bite is present among many but not all cases at the initial visit to the physician. 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...

    Colorado tick fever (CTF), also known as Mountain tick fever or American mountain fever, is a viral disease caused by infection with the Colorado tick fever virus (CTFV), a member of the Coltivirus genera. CTF is transmitted to humans most commonly by the bite of an infected adult wood tick, and while there is no evidence of natural person-to-person transmission, rare cases of transmission by blood transfusion have been reported. The diagnosis of persons with CTF is complicated by non-specifi...

    Colorado tick fever occurs primarily in the Rocky Mountain region of the western United States as well as the Canadian provinces of British Columbia and Alberta. More than 90% of all CTF cases in the United States are reported from Colorado, Utah and Montana. The disease is most prevalent during the summer months between April and August, and is usually limited to mountainous elevations between 1,200 and 3,000 meters. Patients with CTF are most often campers and young men, who have been expos...

    Clinical manifestations of CTF can range from mild to life-threatening depending on the patient’s age and general health. The first symptoms of CTF usually occur 3-7 days after a tick bite, although the incubation period can be as long as 20 days. The initial symptoms of the disease often include fever, chills, headache, muscular and skeletal pain, and malaise. Other symptoms may include nausea, vomiting, stomach pain, light sensitivity and sore throat. About half of all patients experience a...

    An initial diagnosis is based on the patient’s signs and symptoms and confirmation depends on laboratory testing. The appearance of a saddleback fever and the absence of a hemorrhagic rash common to Rocky Mountain spotted fever are clinical indicators of CTF. Leukopenia, a decrease in the number of circulating white blood cells, is the most common laboratory finding in CTF. The immunoflourescent staining of blood smears may be used to identify CTFV antigens, however a confirmed diagnosis can...

    No specific treatment for CTF is available. Management of CTF includes treatment of fever and pain with analgesics and acetaminophen, along with standard infection control procedures. Patients infected with CTF should advise blood collection agencies of their illness prior to donation, due to the risk of transmitting CTF through blood transfusion.
