    Rocky Mountain spotted fever is the most lethal[1] and most frequently reported rickettsial illness in the United States. It has been diagnosed throughout the Americas. Some synonyms for Rocky Mountain spotted fever in other countries include “tick typhus,” “Tobia fever” (Colombia), “São Paulo fever” or “febre maculosa” (Brazil), and “fiebre manchada” (Mexico). It is distinct from the viral tick-borne infection, Colorado tick fever. The disease is caused by Rickettsia rickettsii, a species of bacterium that is spread to humans by Dermacentor ticks. Initial signs and symptoms of the disease include sudden onset of fever, headache, and muscle pain, followed by development of rash. The disease can be difficult to diagnose in the early stages, and without prompt and appropriate treatment it can be fatal.

    The name “Rocky Mountain spotted fever” is somewhat of a misnomer. Beginning in the 1930s, it became clear that this disease occurred in many areas of the United States other than the Rocky Mountain region. It is now recognized that this disease is broadly distributed throughout the continental United States, and occurs as far north as Canada and as far south as Central America and parts of South America. Between 1981 and 1996, this disease was reported from every U.S. state except Hawaii, Vermont, Maine, and Alaska.

    Rocky Mountain spotted fever remains a serious and potentially life-threatening infectious disease today. Despite the availability of effective treatment and advances in medical care, approximately 3% to 5% of individuals who become ill with Rocky Mountain spotted fever still die from the infection. However, effective antibiotic therapy has dramatically reduced the number of deaths caused by Rocky Mountain spotted fever; before the discovery of tetracycline and chloramphenicol in the late 1940s, as many as 30% of persons infected with R. rickettsii died.

    Rocky Mountain spotted fever can be very difficult to diagnose in its early stages, even among experienced physicians who are familiar with the disease.

    People infected with R. rickettsii usually notice symptoms following an incubation period of one to two weeks after a tick bite. The early clinical presentation of Rocky Mountain spotted fever is nonspecific and may resemble a variety of other infectious and non-infectious diseases.

    Initial symptoms include:




    Severe headache

    Muscle pain

    Lack of appetite

    Later signs and symptoms include:

    Maculopapular rash

    Petechial rash

    Abdominal pain

    Joint pain

    The classic triad of findings for this disease are fever, rash and history of tick bite. However, this combination is often not identified when the patient initially presents for care. The rash has a centripetal, or "inward" pattern of spread, meaning it begins at the extremities and courses towards the trunk.

    The rash first appears 2–5 days after the onset of fever and is often very subtle. Younger patients usually develop the rash earlier than older patients. Most often it begins as small, flat, pink, non-itchy spots (macules) on the wrists, forearms, and ankles. These spots turn pale when pressure is applied and eventually become raised on the skin. The characteristic red, spotted (petechial) rash of Rocky Mountain spotted fever is usually not seen until the sixth day or later after onset of symptoms, but this type of rash occurs in only 35% to 60% of patients with Rocky Mountain spotted fever. The rash involves the palms or soles in as many as 50% to 80% of patients; however, this distribution may not occur until later in the course of the disease. As many as 10% to 15% of patients may never develop a rash.

    Abnormal laboratory findings seen in patients with Rocky Mountain spotted fever may include thrombocytopenia, hyponatremia, or elevated liver enzyme levels.

    Rocky Mountain spotted fever can be a very severe illness and patients often require hospitalization. Because R. rickettsii infects the cells lining blood vessels throughout the body, severe manifestations of this disease may involve the respiratory system, central nervous system, gastrointestinal system, or renal system. Host factors associated with severe or fatal Rocky Mountain spotted fever include advanced age, male sex, African-American race, chronic alcohol abuse, and glucose-6-phosphate dehydrogenase (G6PD) deficiency. Deficiency of G6PD is a sex-linked genetic condition affecting approximately 12% of the U.S. African-American male population; deficiency of this enzyme is associated with a high proportion of severe cases of Rocky Mountain spotted fever. This is a rare clinical course that is often fatal within 5 days of onset of illness.

    Long-term health problems following acute Rocky Mountain spotted fever infection include partial paralysis of the lower extremities, gangrene requiring amputation of fingers, toes, or arms or legs, hearing loss, loss of bowel or bladder control, movement disorders and language disorders.

    Most people who develop Rocky Mountain spotted fever - RMSF - do so after being bitten by one of two types of ticks — the American dog tick in the eastern and central United States, and the Rocky Mountain wood tick in the Rocky Mountain states and southwestern Canada. The details are contained in the answer from “Rkanter”, above, and may be checked out in the freebase.com website. To answer your question, in severe cases, the blood vessels, liver, kidneys, intestines, lungs, or brain can all be affected by the illness and may become damaged. About a third of all people with the infection notice that their symptoms appear gradually. Symptoms include a flu-like feeling, such as fever, chills, fatigue, muscle aches, and severe headache. A person may also experience abdominal pain, nausea, vomiting, and diarrhoea and may not feel like eating. Some days later, some sufferers may develop a skin rash that looks like small pinkish-red or dark red spots or blotches. The rash often appears 2 to 5 days after other symptoms start. It typically begins on the wrists, ankles, palms, and soles of the feet and then spreads up the arms and legs toward the chest, belly, and back. As RMSF progresses, the original red spots may change in appearance to look more like bruises or bloody dots or patches under the skin. However, not everyone develops a rash.


    It is extremely important to obtain an accurate diagnosis before trying to find a cure. Many diseases and conditions share common symptoms.

    Yes. Parvo especially can be brought in on shoes. This is why when I had a litter, everybody coming to see my puppies were asked to remove their shoes, and wash their hands before touching my puppies. People will go from kennel to kennel, and I wasn't about to risk them bringing something in to my puppies! Add. Just to say that from around 5 weeks on, the immunity puppies will have taken from their mothers starts to drop off. This is why most vets follow the protocol of vaccinating at any time from 8 weeks on, by which time the level of immunity is probably at it's lowest. If puppies are vaccinated too soon, while they still have some immunity, chances are the vaccination won't take. However, as they are all different, the ONLY way to know for sure when is the right time to vaccinate, is to individually check the titre levels. However, this is costly, so this is why vets vaccinate when they do - the 'mean average'.
