Glossary Introduction Rocky Mountain spotted fever is the most severe and most frequently reported rickettsial illness in the United States. The disease is caused by Rickettsia rickettsii , a species of bacteria that is spread to humans by ixodid (hard) 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.

Rickettsial Diseases Topics [General] Epidemic Typhus Murine (Endemic) Typhus Scrub Typhus ... Bartonellosis Rocky Mountain Spotted Fever (Spotted Fever; Tick Fever; Tick Typhus) An acute febrile disease caused by Rickettsia rickettsii and transmitted by ixodid ticks, producing high fever, cough, and rash. Epidemiology and Pathology Hard-shelled ticks (family Ixodidae) harbor R. rickettsii, and infected females transmit the agent to their progeny. These ticks and some mammalian hosts are the natural reservoirs; animals provide blood nourishment. Dermacentor andersoni (the wood tick) is the principal vector in the western USA; D. variabilis (dog tick) is the vector in the eastern and southern USA. The organism is also maintained in rabbits and other small mammals. RMSF is probably not transmitted directly from person to person even via infectious particles produced by the cough. Small blood vessels are the sites of the characteristic pathologic lesion. Rickettsiae propagate within damaged endothelial cells, and vessels may become blocked by thrombi, producing vasculitis in the skin, subcutaneous tissues, CNS, lungs, heart, kidneys, liver, and spleen. Disseminated intravascular coagulation often occurs in severely ill patients (see Disseminated Intravascular Coagulation under Acquired Coagulation Disorders in Ch. 131).

Symptoms of rocky mountain spotted fever usually begin suddenly http://kidshealth.org/parent/infections/bacterial_viral/rocky.html

KidsHealth Parents Infections Signs and Symptoms: Rocky Mountain Spotted Fever (RMSF) is an infection that is transmitted by ticks. The signs and symptoms of RMSF may follow within 1-14 days of a tick bite. But in many cases, someone who develops the infection does not remember being bitten by a tick. Symptoms of Rocky Mountain Spotted Fever usually begin suddenly. There is a high fever - often 103F (39C) to 105F (40C) - with chills, muscle aches and a severe headache that may center around the forehead area. Eyes may become red, muscles may be tender to the touch, and there may be generalized body swelling. The rash that makes Rocky Mountain Spotted Fever a "spotted" fever may begin anytime between 1-10 days after the fever and headache start, but it most often appears on the third to fifth day. The rash looks like small red spots or blotches that begin on the wrists, ankles, palms and soles. It spreads up the arms and legs toward the trunk, but often spares the face. As the Rocky Mountain Spotted Fever infection progresses, the original red spots may change in appearance to look more like bruises or bloody patches under the skin. Rarely, Rocky Mountain Spotted Fever may cause either mild symptoms or no symptoms at all. But usually it causes a moderate to severe illness that can damage the liver, kidneys and lungs. Before antibiotic treatment was available, about 20-30 percent of people with the infection would die. But antibiotics have helped to decrease much of the suffering and danger resulting from the infection.

KidsHealth Teens Infections Jared loves to hike, so he spends most weekends in spring and summer exploring the foothills of the wooded mountains near his home. Just days after one of these hikes, he suddenly woke up with a high fever, aching muscles, chills, and a bad headache. He thought he was getting the flu. However, a few days later, he started getting a spotted red rash on his wrists and ankles. Jared - who's pretty savvy about the outdoors - wondered if his illness had anything to do with the ticks he'd seen in the thick grasses and bushes along the trails. A trip to the doctor confirmed his guess - Jared had Rocky Mountain spotted fever. What Is Rocky Mountain Spotted Fever? Rocky Mountain spotted fever (RMSF) is a disease caused by infection with Rickettsia rickettsii bacteria. This species of bacteria is usually carried by two kinds 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 bacteria that cause the infection are transmitted to humans by tick bites, so RMSF occurs most often when ticks are active. Over 90% of cases occur in the spring and summer months between April and early September. Less than 3% of ticks actually carry the

Other ticks transmit the infection in the southern U.S. and in Central and South America. Contrary to the name "Rocky Mountain," most recent cases have been reported in the eastern United States: North and South Carolina, Virginia, Maryland, Georgia, Tennessee, and Oklahoma. Most cases occur in the spring and summer with about 1,000 cases reported per year. Most of the reported cases have been in children. The risk factors include recent hiking or exposure to ticks in an area where the disease is known to occur.
