    Apr 15, 2020 · Rocky Mountain spotted fever (RMSF) is not contagious from person to person. The disease requires, in most instances, transfer of bacteria from the tick bite to the individual. Infrequently, some people can become infected with the bacteria if they contact tick droppings or crushed dead ticks.

    Anaplasmosis, ehrlichiosis, and spotted fever group rickettsioses are treated with doxycycline. Clinical suspicion of any of these diseases is sufficient to begin treatment. Delay in treatment may result in severe illness and even death. The regimens listed below are guidelines only and may need to be adjusted depending on a patient’s age, medical history, underlying health conditions, pregnancy status, or allergies. Consult an infectious disease specialist in cases of pregnancy or life-threatening allergy to doxycycline. NOTE:Use doxycycline as the first-line treatment for suspected RMSF in patients of all ages. The use of doxycycline to treat suspected RMSF in children is recommended by both the CDC and the American Academy of Pediatrics Committee on Infectious Diseases. Use of antibiotics other than doxycycline increases the risk of patient death. At the recommended dose and duration needed to treat RMSF, no evidence has been shown to cause staining of permanent teeth, even when...

    After an infected tick bites a human, the bacteria are released into the bloodstream. There they attack cells that line the blood vessels and smooth muscles that control the constriction of the blood vessel. They set off an immune reaction in the blood vessel causing the vessel to swell and become leaky. This process can occur in any organ system in the body causing a wide variety of symptoms.

    The incubation period is 2 to 14 days after the tick bite. The average incubation period is 7 days. The most common symptoms of Rocky Mountain spotted fever are the abrupt onset of fever, severe headache, muscle aches, and vomiting. Other symptoms that are less common are abdominal pain, swollen lymph nodes, cough, stiff neck, confusion, and coma.

    The rash associated with Rocky Mountain spotted fever usually starts around 4 days into the illness. It looks like small, red, flat spots starting most often on the ankles and wrists, and then moving to the palms, soles, and trunk. As the rash progresses, it becomes bumpier. Approximately 10% of those infected never get a rash.

    Overall, Rocky Mountain spotted fever is fatal in 3% to 7% of cases. However, it is fatal in over 30% of those who are not treated. The mortality is higher in people over 40 years of age. Death usually results from shock and kidney failure.

    Rocky Mountain spotted fever is diagnosed mainly based on symptoms. There are no reliable laboratory tests to diagnose Rocky Mountain spotted fever while the patient has the disease. Most laboratory tests that are specific for the bacteria involve obtaining one blood test while the patient is sick and another in 4 weeks to see if the immune system has built up antibodies to the bacteria. Obviously, waiting for this second test to return before making a diagnosis is fruitless and only useful in retrospect. Other lab tests that may indicate Rocky Mountain spotted fever are a low white blood cell count, low platelet count, or elevated liver function tests. The rash is usually the key to diagnosis since not many rashes affect the palms and soles.

    Rocky Mountain spotted fever is treated with antibioticssuch as doxycycline, tetracycline, or chloramphenicol. Most providers will prescribe one of these antibiotics on the assumption that the disease is Rocky Mountain spotted fever and confirm the diagnosis with another blood test in 4 weeks. Pregnant women should not take doxycycline or tetracycline. Since chloramphenicol is available in the US only in IV form, pregnant women should be admitted to the hospital.

    Preventing Rocky Mountain spotted fever involves preventing tick bites. Children and adults who are outside in tick-infested areas should wear long clothing and tuck the end of the pants into the socks. Insect repellant should be applied to shoes and socks. Permethrin products are more effective against ticks than DEET products. Check for ticks attached to the skin every 2-3 hours while outside, then check thoroughly once a day. Favorite hiding places for ticks are in the hair so check the scalp, neck, armpits, and groin.

    care provider? - The incubation period in humans is 2 to 14 days, with an average of seven days. In the early stages, RMSF fever can be difficult to diagnose. A classic triad of fever, pin-point rash and tick exposure is suggestive; however, the rash appears several days after the other symptoms, and the tick may not have been noticed.
