		Rickettsia rickettsii is the organism responsible for RMSF.
		Seasonal outbreaks of RMSF parallel the activity of the tick; 90% of cases are reported from April 1 to September 30, with peaks in May and June.
		RMSF must be considered in any febrile patient in an endemic area, regardless of atypical presentation, lack of rash, or apparent lack of tick exposure.

	Rocky Mountain Spotted Fever
		RMSF occurs most often during months when ticks are active - usually in the spring and summer, between April and early September.
		Although RMSF is most common in the southeastern states (Virginia, Georgia, and the Carolinas), it occurs along the entire East Coast northward to Massachusetts, and also westward into Tennessee, Kentucky, Arkansas, and Oklahoma.
		The bacteria Rickettsia rickettsii that cause an RMSF infection are carried by the dog tick (Dermacentor variabilis) in the eastern United States and by the wood tick (Dermacentor andersoni) in the Rocky Mountain states.

	Rocky Mountain spotted fever (tick-borne typhus fever) : Bureau of Communicable Disease : NYC DOHMH
		RMSF is transmitted to humans and other animals by the bite of an infected tick.
		RMSF is characterized by the sudden onset of moderate to high fever (which can last from 2 to 3 weeks), severe headache, loss of appetite, fatigue, deep muscle pain, chills and rash.
		RMSF is diagnosed based on clinical presentation of symptoms or a positive antibody test to the Rickettsia ricketsii bacteria.

	Rocky Mountain Spotted Fever (Site not responding. Last check: 2007-09-10)
		Rocky Mountain spotted fever (RMSF) is a disease caused by a microorganism transmitted to humans by the bite of an infected American dog tick (Dermacentor variabilis) and by several other tick species.
		RMSF is spread by the bite of an infected tick (the American dog tick, the lone-star tick or the wood tick) or by contamination of the skin with the tick's body fluids or feces.
		RMSF is characterized by a sudden onset of moderate to high fever (which can last for two or three weeks), severe headache, fatigue, deep muscle pain, chills and rash.

	Rocky Mountain Spotted Fever
		In individuals with G6PD deficiency, fulminant RMSF is thought to be related to unknown secondary effects of acute hemolysis on the R. rickettsii infection.
		Some have speculated that the tissue and organ injury in RMSF may be due to the widespread development of obstructive blood clots (thromboses) within blood vessels, leading to a decreased supply of oxygenated blood to certain tissues (ischemia) and associated, localized areas of tissue death (necrosis).
		RMSF is most commonly seen in wooded areas or those with high grasses (i.e., within rural and suburban regions), although the disease has also been reported in urban areas.

		RMSF is characterized by fever, myalgias, headache, and a petechial rash.
		RMSF is a potentially fatal disease with a mortality rate as high as 30% in the preantibiotic era.
		Further, RMSF should be considered in family members and contacts who have febrile illness and share environmental exposures with the patient.

	Rocky Mountain Spotted Fever Information on Healthline
		Rocky Mountain spotted fever (RMSF) is a tick-borne illness caused by a bacteria, resulting in a high fever and a characteristic rash.
		The bacterial culprit in RMSF is Rickettsia rickettsii.
		Diagnosis of RMSF is almost always made on the basis of the characteristic symptoms, coupled with either a known tick bite (noted by about 60 to 70 percent of patients) or exposure to an area known to harbor ticks.

		RMSF may cause inflammation in the eyes resulting in squinting, excessive blinking, and signs that look similar to conjunctivitis.
		This disease is distinguished from RMSF on the basis of cerebrospinal fluid analysis and a positive RMSF titer.
		Most pets with RMSF require hospitalization for initial treatment although length of hospitalization depends on the severity of infection and clinical symptoms and may vary from 24 hours to several days.

		The bacteria that cause RMSF are transmitted from a tick to a person while the tick is attached to the person's skin.
		For many people, symptoms of RMSF begin suddenly, although this isn't always the case: About a third of all people with the infection notice that their symptoms appear gradually.
		As RMSF progresses, the original red spots may change in appearance to look more like bruises or bloody dots or patches under the skin.

		RMSF is a tick borne febrile illness most commonly characterized by acute onset and usually accompanied by malaise, myalgia, headache, nausea, and petechial rash.
		This rash is present in 2/3 of cases and appears as small red spots or blotches that begin on the wrist, ankles, palms, and soles.
		Various wildlife species serve as hosts of the RMSF rickettsial organism and the ticks themselves: deer, fox, wolf, badger, opossum, rabbit, raccoon, skunk, squirrel, deer mice, and chipmunks.

		Treatment for RMSF with antibiotics (usually doxycycline) is very effective at reducing the severity of the disease.
		Laboratory testing for RMSF typically consists of blood samples taken in the early stages of the illness (acute) and follow up (convalescent) specimens taken at least four weeks after the first specimen.
		The frequency of reported RMSF cases is generally highest among males and among Native American and Caucasians races.

		Diagnosis of RMSF is almost always made on the basis of the characteristic symptoms, coupled with either a known tick bite (noted by about 60-70% of patients) or exposure to an area known to harbor ticks.
		Although the death rate from RMSF has improved greatly with an understanding of the importance of early use of antibiotics, there is still a 5% death rate.

		Rocky Mountain spotted fever (RMSF) is an infectious rickettsial disease of dogs, that is characterized by severe vascular damage.
		Distribution of the disease is related to the distribution of the vector ticks Dermacentor variabilis, the American dog tick found in the eastern United States, and Dermacentor andersoni, the wood tick, which is the principal vector in the western United States.
		For this reason, canine RMSF is a disease that presents in the spring and summer (April to September).

		From 1996 through 2000, 13 cases of RMSF were reported in our state, including one fatality.
		Risk factors for fatal RMSF include age >40, nonwhite race, male gender, absence of headache, lack of history of tick attachment, delay in treatment, gastrointestinal symptoms, and no treatment by the fifth day of illness.
		The American Academy of Pediatrics lists doxycycline as an option for children under age eight because staining of the teeth is dose-related, is less than with tetracycline, and tetracycline is active against both RMSF and erlichiosis whereas chloramphenicol is not.

	OCC-ENV-MED-L archives -- October 2000 (#37)
		Patients with Rocky Mountain spotted fever (RMSF), a tickborne infection caused by Rickettsia rickettsii, respond quickly to tetracycline-class antibiotics (e.g., doxycycline) when therapy is started within the first few days of illness; however, untreated RMSF may result in severe illness and death.
		In its early stages, RMSF may resemble other infectious and noninfectious conditions and can be difficult to diagnose even for physicians familiar with the disease (4,5).
		Because only 3%--18% of patients present with rash, fever, and a history of tick exposure on their first visit (4--6), physicians should consider RMSF in infants and children even when one feature is lacking.
